AMS Twin Tip Review
 

Well after spending countless months researching different exhausts, i finally settled on the AMS Twin Tip. I ordered their catback and testpipe to accompany my AMS Short ram intake that was already on the car. All Three products have been top notch quality. I received the exhaust in a couple days and everything was packaged very securely and wrapped carefully. They forgot to send out the silencer plates with the exhaust but i notified them of it and they immediately had them shipped out to me. +1 for customer service.

Sound
Since i still havent gotten around to installing any of the plates this exhaust is very loud. I actually like the tone of the exhaust but with most of the exhaust traveling out the unmuffled tip, it screams. It crackles rather nicely on downshifts and i can hear some backfires as well. I have not yet tried any of the silencer plates but im sure that this will be a good alternative for people who want a milder exhaust note.

Performance
The butt dyno seems to think that i picked up a decent amount of power with the combination of the catback and test pipe. I feel just as much if not more of an increase than i did with the intake, so i would assume ive picked up 20-30hp. I cant wait to get tuned and see what numbers i can put down with the stock cat and exhaust restrictions removed.

Quality
The welds on both exhaust and test pipe were beautiful and it appeared to be made of high quality materials. Perfect fitment and no rattles/rubbing anywhere. I tried to install myself but couldnt get the catbolts off so i ended up bringing it up to a friends shop and having him throw it on his lift to do it for me. He actually commented on the fitment of the exhaust and said how well designed it was. My favorite thing is the versatility of this system. While i enjoy the sound, i know i can always quiet things down if i desire.

and the video. Sound seems slightly off to me. Can never truly capture the sound well through a pos camera. The camera's memory filled up right as i started to get on it.

This video is actually on a camera phone but is a much truer representation of the sound imo. This is a more accurate recording. http://www.youtube.com/watch?v=eIPxu...e=channel_page

{thumbup} to the Sabres license plate and frame....where do you live?

albany ny. I love the sabres! My whole family is from batavia.

sick, too bad im not baller enough to afford one haha.

get tuned at DG motors

I hate that exhaust, not that it looks bad at all. To gimicky, different plates:crap: I like to see balance

hows the car running / idling without the tune? Im getting ready to pull the trigger on the AMS intake / test pipe / twin tip myself , just a little concerned about running around un-tuned

Im really considering it. Still looking at CBRD as well. I have full confidence that either place will be great.

No issues for me. Great combo imo cant wait to get tuned though.

While the plates are a funny idea. The option to change sound is nice, knowing that you can quiet it if need be. There is confidence is knowing your not gonna be stuck with an exhaust that is annoying and loud, you can change it to suit your taste.

After going a week with no silencer plate, I installed the one that still allowed the most flow to the passenger side tip. No noticeable power loss, and it definitely quieted the exhaust down a bit. I actually think it sounds better with the plate installed.

The best option is that you can pull off the muffler section to run straight-through and shed some weight for track days, all by flipping off a little v-clamp that takes 60 seconds.

wow, that thing is loud as hell! I hope the the plates quite things up a lot, if not, I guess I'll scratch this exhaust off my list.

well chad at CBRD and charlie at DG, tune the same so it doesnt really matter who you get tuned by.

i hope it's just your recorder, because it sounds like :crap:

is it just me or is there a dent on the muffler

I'm sorry but I'm not a fan of the idle exhaust sound...

i also think i may have a small exhaust leak because i currently have no plate installed at the vband joint. and right now its bascially unmuffled, i think with a plate and some of the exhaust travelling through the muffler it will both quiet it down and mellow the tone down.

i think it definitely sounds better in person but as i said earlier this is with no plate what so ever. traveling through the muffler will probably change the tone down and make it not as raspy. IMO, it sounds much better not through my sisters pos camera. I am probably going to try out some of the plates and see how i like it. I have heard several people say they like the tone better with a plate in it. (minimal performance loss according to edmunds too {thumbup})

there is a small indentation. I believe it happened during install. It really is barely noticeable but the way the light it the exhaust, it really made it stick out.

This video is actually on a camera phone but is a much truer representation of the sound imo. This is a more accurate recording. http://www.youtube.com/watch?v=eIPxu...e=channel_page

Cant see the youtube one and the other one makes it sound bad. Im sure it doesnt though

sounds good, wish I waited.

it really does. Some people are saying they don't like it after listening to the first video, but it doesnt do it justice. I would recommend it. This is one of the several sounds/tones that can be achieved with this exhaust just by changing the plates.

Looks/sounds pretty good.

Could you post another with it 50/50 and 100% muffler?

Thanks for the video review! There are barely any online to watch! I can't wait to get this exhaust.{thumbup}

I haven't tried the fully-open passenger side case, but I can confirm the exhaust sounds nothing like that first video with the small diameter plate installed. It's just a bit louder than stock with a nice idle rumble and a great rev'd-up roar that's not raspy or harsh.

I think I have a bit of an install problem on mine somewhere since I'm getting a weird high-frequency noise (I have a post on the AMS forum asking for help), so I'm going to assume it's not normal for now. Assuming that, if you ignore the weird chirping from this video I made it seems to get the sound down a little better:

Edit: I just realized bwagner is using a test pipe, and mine's bolted to the stock cat, so that will change things pretty significantly.

i can try to get some videos of the different plates when i put them in.

I'd be curious if you hear the same high-frequency noise mine makes with the smallest diameter plate installed.

Thanks! Oh and great exhaust! I'm going to order one very soon.{thumbup}

Bump for new videos!:D

i still wanna throw in a disc and try that out. im getting an o2 dump. wanna have the exhaust sound mellow cruising around and then scream when the wastegate opens.

looks nice!!

Love the exhaust, hate the tips. Stealth or not oval tips are.:thumbdown I'll be in the market soon and this would be at the top of my list if it wasn't for the tips.

I just got my twin tip put on last week. Love it! run it wide open. The guys over at AMS do a great job. The sound is great. It is great living so close to AMS. Thanks Dan

+1, I'm pretty sure I'm gonna go with HKS

I replaced my T1R twin tip on my MR with this exhaust the other day. The T1R was too quite, almost stock. I don't like the engine tone, so wanted something with a bit more growl. The AMS exhaust was the ticket. Wide open, the noise is a little too much inside the cabin, but with the plate with the largest hole, the exhaust tone is now perfect. I wanted something I could adjust and not be stuck with another exhaust I did not like. The T1R tips also were a bit too recessed for me.
However, my passenger side exhaust tip sits lower than the driver's side and sticks out just a tad more as well. Anyone else with this?

I had that same issue. Took it back to AMS the next day and they took care of me right away. There was an issue with the tip being a tad longer. They took it off and trimmed it down. All fixed looks and sounds great.

i installed this 2 weeks ago and also got tuned, i notice backfire or popping sound when decelerating around 2000 rpm or less. is this normal?

i get the popping on decel too. sounds great. Right now im running the pass tip fully closed off, not too loud but has a nice tone. when my wastegate dump opens it screams.

another vid coming soon possibly

Mine pops quite a bit, and appears to be at least partially dependant on what plate you have installed. I'm temporarily running wide open on the passenger side, and the amount of popping has increased dramatically over even the plate with the largest diameter.

I have a couple videos up if anyone's interested. Not of the popping, but the sound of the general idle and low RPM revs:

Passenger side wide open
Largest diameter plate

One other thing to note. If you're not running wide open on the passenger side, do NOT allow your tuner to use an exhaust tip wideband on the passenger side. It really hoses the readings at low RPM, and you'll freak out thinking you've been running in the 14s. This is from experience ;)

absolutely agree with you.

One thing I noticed in your videos was how awkward the passenger tip looks with the V-band clamp behind it.

It could be because I washed the clamp when I was messing with it and everything else was filthy. In any case, you're not often looking at the car from below ground level, so under normal conditions you can't really see it.

You can fix that very easily... Just loosen the t-bolt clamp that attached the muffler side to the right side. You can adjust the height up and down quite easily. As soon as you have it in the desirable position just retighten the t-bolt clamp and it will stay.

(NOTE: it tends to move while tightening so be sure to hold the left tip tightly in place while retightening the bolt)

I like this exhaust a whole lot, great gains, sound, looks, quality and fitment. I had the same setup running WITH the cat and it sounded fantastic! I just bolted up a test pipe last night and it got to a point where I was embarrased to drive down the street because of how loud it was! It is essentially a straight pipe now on the right side.

I took it for one drive (on city streets & highway) and decided to put in the largest diameter disc. It sounds like the cat is back on. I can NOT feel any noticeable power loss, but the disc is visible in there and looks kind of odd. I'm sure once the tar from the exhaust covers it it won't be so noticeable.

UPDATE: I can't see the disc in there anymore... It just took about 2 days worth of driving for it to be engulfed in black.

Done: much better. The passenger tip still extends slightly longer than the driver's side, but now that they are both level, it is barely noticeable.
