Just go with a Megan racing one. They are cheaper, have a resonator built in and you can just buy a cel fix for like under $10 bucks and your done. A pipe is a pipe as long as the welds are good quality and flanges are correct no one will give more power or anything. Same size that is of course.

 

...assuming yes that the pipe is of good quality and has good welds, which isn't always the case. I have both a Berk 63mm and a T1R 70mm, and they are both well made TP's.

 

were can i pick up a cell fix or a fouler if i go with one not built in

 

ok i bought a berk test pipe and love it... it sounds a little different higher RPMs and NO CEL i have had it for about a week now and going strong doesnt smoke doesnt look like carbon is on bumper but i also keep it pretty clean... i rarely smell exhaust when the top is down hint the top is down guaranteed to smell someones car but berk test pipe is a great buy 2 thumbs up! you wont regret the purchase.

 

Here is one. All it has to do is hnold the o2 sensor further away so it won't realize that there is no cat.

Heres one ready to go if you want it plain and easy from ebay.

CEL fix.

It just screws in right where the o2 sensor normally does and then you screw your o2 sensor into the cel fix.

 

Pretty much any auto parts store.
