I shall pick up the torch brother!!!


Newbies beware.

 

The Greddy Ti is very light, I'm fairly it's one of the lightest. Do be aware that there are two types. The Power Extreme Ti and the Power Extreme Ti-R. The Ti is slightly narrower bore (70mm) while the Ti-R is larger at 80mm.

The funny thing is that for the Ti, the IX uses a different code from the other models (10132602) and it is specific to the IX.

The Ti-R on the other hand, uses the same code 10131051 for both.

The difference between the two is that the Ti (which is what I have) has a thin cylindrical silencer between the cat and the rear muffler, where as the Ti-R is a straight pipe all the way hence it is louder. I guess this silencer is what doesn't fit on the IX.

 

Another make you should look at if you want the ultimate in lightness is Kakimoto. I don't know if you can get their product in the US.

They don't show weights on their site http://www.kakimotoracing.co.jp but their Full Titanium system for the IX basically has nothing more than a pipe and a cylindrical end can. I don't think you can get much lighter than that, unless you go for a smaller bore of course. And it will be loud as bastard5.

 

I'm far from a noob, and I've had Greddy Ti's on my past couple of Evo's. If you don't appreciate or cannot afford high quality parts why denigrate those that can? I highly recomend the Greddy piece, and given the purpose-biult nature of the Evo I think it complements it perfectly.

 

If you are going to keep the stock DP and Cat then go Works or Buscher Muffler Delete Pipe. Light weight, inexpensive and actually not too loud if you keep the stock DP and Cat.

I sold my EVO and have a slightly used Greddy Ti system for sale here:

Its a work of art.

 

My point exactly. I want to let the engine breathe a bit better but at the same time, I'd like to cut some weight off the car as well. I'm not doing a turbo back exhaust because it will void my warranty. I've already had discussions with the service dept where I bought my car and the general idea is, cat back is fine and an intake is fine. Everything else that you can't see (ie ECU flash would be ok) because they'd honestly not have any reason to look at it. If I were to do a turbo back exhaust and have drivetrain problems, it the turbo back could be used as grounds to void my powertrain and engine warranty. Perhaps in your area the dealerships are more reasonable, but that's what I have to deal with here. So I plan on keeping the stock downpipe and cat. If I can pick up another 10 - 15 whp from the Greddy cat back while at the same time saving some weight, why not. I'm not out to build a 500whp monster. I just want to do choice mods to the car to pick up a bit more power while at the same time keeping it totally streetable.

I'm not sure where Warrtalon gets off calling me a "n00b" just because I asked about a Titanium exhaust. I'm not new to modifying cars. I'm not some 16 year old who's daddy just bought him an evo and wants the "mad JDM tyte" parts. I spent alot of money on the car and I'd like to use the highest quality components on it when making modifications. I'm not knocking the other exhaust products that you mentioned, but they don't offer the weight savings that I would get from titanium. At any rate, I thank all the other users who offered their advice and experience. It's given me food for thought when making my decision.

 

cat-back....blah!

 

I can really see your point, if you had a first gen talon and you were building it you would probably put the cheaper brand products on it but having a 30 thousand dollar car you dont want to disgrace it a ruin the car with some cheap exhaust when you could just wait for another two or three weeks and have a really nice exhaust to compliment the evo.

 

Exactly. Not that the other products that were mentioned aren't quality pieces, it's just that they don't give me the weight savings that I'm after.

 

if your that worried about weight savings why stress about 2-3lbs on your exhaust???? my evo's at 2950lbs w/ a little over a quarter tank of gas....and a "jic stainless steel exhaust"!!! so if it's that big of a deal, worry about your big weight savings elsewhere.....

 

I'm actually thinking of adding a Ti exhaust as well. I dont think there is anything wrong with spending a few hundred more for losing 10 lbs. However some Ti kits are absolutely outrageous ... Amuse, ARC, etc cost way more than the Helix or the Greddy kit. I'm just pissed about the way the Greddy fits or I'd have one buy now. Whats $800 when you car is $35k?

 

Yea, I see it as taking a ton of weight off of the rear to middle of the car. Same as spending $170 on a Braille battery - to lose 20lbs from the front of the car.

I'm just thinking of how to make an adapter plate to make the Greddy Ti stick out an inch more. I like the exhaust because it uses flanges over clamps (JIC, Buschur, etc.) Back on topic it would be cool to see some actual weights from other SS exhausts.

 

Two of my friends that have Evo's have the Greddy Titanium, one of them has the titanium cat back on his Evo 9 MR and no fitmet issues.

Get you feedback from people that actually has them. PM Edwin, he has one and no problems fitting it. Edwin will direct you to his friend who also has the Titanioum Greddy cat back on the Evo 9 without fitment issues.

Lets not speculate..

 

The thread originator already has his mods and went with a used HKS hi-power cat-back. He is at 340whp with the proper combination of mods and did not get a titanium exhaust.
