I just got my Berk Test Pipes installed. My first impression driving with them was this I was afraid the nice deep exotic type of tone the RSR had would go away. However it was only magnified. The performance factor is what really amazed me. For those that say most bolt ons don't do much they need to give test pipes a try. From 1-3K RPM it feels a little more free in the revs. After 3K RPM and up, WOW it flies. Its like the car was restricted big time with the cats. So far the welded 02 fix that the Berk pipes have has worked great. Here are some before and after videos. Sorry for the KS wind, I waited a couple days and it wouldn't stop blowing so I just took some vids anyway.

Before: RSR Exmag GTII, Motordyne 5/16 iso plenum spacer, UR underdrive pulley and JWT popcharger.

one of the best sounding exhaust to me i just cant stand the looks of it. Sounds good though man.

 

1st after vid is Vid was removed bc it SUCKED hahah

 

+1

The exhaust sounds great but it's a major eyesore..

 

Thanks for the comments I can agree, they do stand out but the sound is what sold me. Sorry about the bad link streetfire is having issues I will try and upload again tomorrow.

 

I've heard that exhaust before with test pipes and its SO LOUD!!!!!! still sounds good though

i dont know how you'll be able to bear with it hahaha

 

Haha, really though 55mph and under it isn't too bad. No drone or anything like that. 65mph on up there is a slight drone, but its def. still quieter than my old S2000. I have some videos of that on streetfire too. That was really annoying!

I couldn't be happier with how it all turned out.
