Hey guys I just installed my Christmas present to myself (it came early ) a slightly used (S2Fire of AJ-R) T1R 70EM Titanium exhaust and test pipe. He provided me with all gaskets and what not.

After installed the exhaust, I obviously decide to take it for a spin. The first 1st-2nd @ 9k shift I hear what sounds like a whoosh, or rush of air. This ONLY happened at high RPM shifts, more pronounced 1-2 though. This also happens while OFF the throttle, and immediately goes away upon applying throttle in second gear.

I don't believe it is an exhaust (air) leak seeing as I only hear it at high rpms, off the throttle.

Any help of ideas would be appreciated!


MERRY CHRISTMAS!!!

 

is this your first non-oem exhaust?

 

 

lol funny... but no.

this is my second pricey exhaust on an s2k. my previous was a 60rs on my ap2.

 

Is it still happening? And, how long was the exhaust off the other car? The only thing I could think of is the first few runs, there might have been dust and debris in there?

 

ok. i was asking not to insult, but because the lack of sound from an oem exhaust can sometimes cover bad shifting/gas habits...for example, pressing in the clutch and not letting off the gas fast enough, causing the rpms to jump a little before dropping and causing that woosh noise.

 

I had a little backfire-esque "whooshing" on my T1R 70 v3 single with test pipe. I though it sounded pretty sweet.

 

We'll i've only driven the car once. I posted this because I have never had this happen before. I do not know how long the exhaust was off the other car, couldn't be too long since they havent been making this exhaust for that long and he had it for 4 months.

 

no insult taken. no bad shifting here. The sound comes when im entirely off the throttle for a split second while changing gears. and its not an "exhaust" sound.

thanks for the ideas. keep them coming.

ill report back after a few more drives

Listen to the ARC Exhaust in the video. It's around 2:00 minutes. Does it sound like that?
