AMS Truth in Results: Full AMS Exhaust Test
Even in the event it was just from the downpipe that is even more reason to run an AMS widemouth Downpipe

These results look about right.
There is nothing odd about these results.
As one of the largest users of AMS parts I can tell you the parts work even better when used in combination.
Sometimes using them with outside parts doesn't provide the desired result. :-)

I don't think I've ever seen a true 3" inner diameter exahust. They're pretty much all 3" with a 0.05" wall thickness, which I assume is because that's what the tube stock is typically available in. Most of the systems I see just quote the 3" outer diameter and make no mention of wall thickness, and I was surprised to see AMS went into that much detail on their specs.
In any case, it is 3" all the way through, according to their page.

I am also running the AMS widemouth downpipe and I love it.
same dyno both times? Yes all 3 times - DynoJet
Was boost altered at all? I will find out
wast the car tuned following those parts being installed?
Yes in the following order:
Stage 1 - 309AWHP292AWTQ with HKS-Drop-In only
Stage 2 - 318AWHP/303AWTQ with HKS Drop-In/AMS FMIC/AMS TP/Buschur Cross Flow CBE
Stage 3 - 312AHWP/295AWTQ with HKS Drop-In/AMS FMIC/AMS TP/Buschur Cross Flow CBE/AMS Intake/AMS UICP/MXP Downpipe
Stage 4 - 330AWHP/334AWTQ with AEM CAI/ETS FMIC/ETS UICP/ETS LICP/ETS HFC w/ CEL Fix/ETS Downpipe/Buschur Cross Flow CBE
Thanks Sean for your input.

Once you factor in the difficulty of installation, the test pipe is the obvious choice. I've decided to hire a shop to install the DP after reading the install threads on here (4 hr install without a lift & a few people break bolts off in the turbo requiring removal of the turbo to fix it).

just a quick question. i am a big ams fan, but i had a friend that had is car tuned, then later did a stroker kit. ams you guys tuned his car and he recieved 1hp to the wheels. he later had many problems, and people at ams said that it is his problem not theirs. i want to know whats up with that, because im a little nervous dealing with ams after hearing this. pm me if you want or reply here, but i would like to know, and i think others would to.

Generally speaking we see a mild HP gain when going to a 2.3. Several factors can affect how much or little that is ie: Compression, Cam selection, climate etc. The major benefit of going with a stroker motor to improve spool time and thusly torque as well. You mentioned it was only a 1hp difference….was that a comparison of peak numbers? The reason I ask is if the turbo was close to its limit before the 2.3 then the 2.3 is really not going to allow it to make more HP. The more pertinent comparison would be the entire graph itself, mid range, spool up etc. Peak numbers are just that…peak. The entire curve it what is more important. I would be interested in seeing that.
First and foremost I am sorry that he was having problems with the car afterwards. What where these problems? I assure you whomever he talked had no intention of coming across how he did. Sometimes in times of haste here at the shop we can sound a bit rushed and preoccupied due to the number of calls we get. If he felt he was not treated fairly I would kindly ask that you please give us a chance to redeem ourselves and show you why we value our customer service so highly. We would love to talk your friend through any problems he might have or had. Thank you and again we do apologize for coming off as anything other than helpful.
Dan, thanks for replying. Well of course i am still a big fan of AMS, and plan on doing business with you all. I dont remember exactly what problems he is having, but i know the car is parked in his garage caues it isnt running properly. So he is riding around in his girlfriends evo. I will let him know that AMS sends apologies and would like to speak with him. Again thanks for replying. Robert

Conclusion:
my friends car had a problem that i don't know any details about but i thought i would derail this thread to complain about my friends (hearsay) experience. Tell your friend to pick up a phone next time or start his own thread.
talk about sgt petty....

Well i was explaining that issue for me. The purpose of the question was for me so that i understand what was going on so that i am comfortable with ams when it comes to my car. Next time understand what you are reading before you talk about derailing a thread. I think this one went over your head.
Those gains sound about right for test pipe and down pipe. It would have been nice to compare just the catbacks instead of changing that up as well. There wasn't a constant in the equation because that was changed.
