I dynoed 348.5 on a dyno jet with T1R testpipe (63mm) and Spugen 2.5 inch Titanium Exhaust with the Vortech SC

 

This is my dyno of before and after the T1R testpipe. Don't mind the VAFC tuning thing, I went there for that but decided not to and they never changed the name of the dyno run.

 

So you picked up 16hp with JUST a test pipe aka no cat.?

That is some HP gain IMO. Usually it takes some major mods on other cars to see that kinda jump. Im still new to the S2K game and jus tryin to learn about it all and the mods and power that can be achieved.

 

Correct


A testpipe usually nets some nice gains with a more free flowing aftermarket exhaust system.

 

thanks for the responses, where did you purchase your test pipe from spec.
what website and how much?
and how long b4 you got it?

 

aj-racing.com and its around $145 shipped when all said and done, also take a week and half to get it since its comming from canada....

 

Assuming they're both really test pipes and not some sort of resonator cat replacement, they should be identical. In many places, a local exhaust shop will make a test pipe for you for around $50...
