Whats a good reliable test pipe and where should i order it from? i have stock headers and a comptech exhaust how much louder is the car and does it trigger a CEL?

 

There are many TP's out there that work just fine. Berk and T1r seems to be the most popular. Then there is Megan and Invidia. There are more then that but the more "JDM" you get, the higher the price will be just for a small pipe.

The Berk pipe comes with a built in CEL fix. The others you can just buy 2 spark plug Anti-foulers and use that for a CEL fix (use a search to see how).

I've never had an aftermarket exhaust without a test pipe so I don't know if it makes it louder or not. I've got to imagine it would add a little volume. I have an HKS system and it sounds great and isn't really loud at all (compared to the Invidia or a single)... oh, and I have an Invidia TP.

edit....before everyone flames you, there is a TON of info on the site on TP's already. If you do a search, you'll find more information then you really need. search is your friend

 

its not to bad with the comptech thats the setup Im running right now....compared to when I had my spugen catback on its 10x quieter

 

:lol:the t1r's are cool, they have tabs that allows you to reattach the stock cat cover so the po po cant pull you over for not having a cat and its for this reason that i like the t1r

 

Maybe the 63mm T1R TP does, but the 70mm does not.

then evasive is lying in this listing. 70mm test pipe, the pic shows tabs.

 

does it matter what mm tp i get and how hard is it to get rid of the cel light with a tp

 

theres a DIY CEL fix in the UTH section using spark plug anti foulers, but i cant speak to how well this works as i have no tp. i'm still shopping for one.

 

The spark plug anti foulers work great. I've had my TP on for 2 years with no CEL....They come in a pack of 2 so you only need 1 pack. I don't remember exactly how much they cost but it's under $5

 

Don't know what to tell you. My 70mm TP does not have the tabs and has two O2 bungs.
