It was a 14 whp gain with the T1R test pipe.

 

Actually, I take that back... It was a 14 whp gain with just the exhaust, and about a 20-21 whp gain with the test pipe.

 

HKS FTW

 

 

i have an ap1 with a comptech exhaust like cory and terry said. i cant imagine there being much sound difference between ap1 and 2, i also have a t1r 63mm test pipe. honestly i love it. awesome sound and looks stock. no drone either. if you dont mind coming to the peninsula i'll let you drive the car.

 

^^^ Heard this car at WOT a couple weekends ago... It does sound great!!

 

I have the 63mm TIR sparrow and the T1R-EM dual is much quieter based on the videos I watched.

Here are some clips of the T1R 63mm sparrow on my car. Not too quiet but these are both with the T1R test pipe as well. The cat quiets it down a little bit.

If you are interested in the 63mm dual I have, I am looking to swap for a stock exhaust +cash on the buyers end. But it might be a little to loud for what you are looking for.

Thanks everyone for the responses. I've talked to Jack in the Box and I might meet up with him sometime. The T1R 70EM dual does sound nice on video, but the looks are kind of? for me. I like the oem style, look, and location of a muffler. The T1R 70EM dual might be an option down the line but I have a BB S2000 and seeing the exhaust below the rear bumper "stainless steel shine" does not look good to me. I might have it powder coated black so the shiney part would go away. The Comptech is also stainlees steel but is more tucked up into the original muffler location so it is not as noticable. Any more info would be great.

 

are u serious? almost 15whp with just the exhaust? sounds almost too good to be true!

 

That's what I said. Click on that link I posted a few posts up.
