i am soon to be in the market for a test pipe and i was looking around and found a t1r CEL fix. one is straight and one is an elbow shape. i have heard back and forth that the berk TP has it already and no CEL, but some do for some reason. do you think that the elbow shape will work better than just the spark plug anti foulers? here is a link to it T1R CEL fix lmk what you guys think



also i have been debating on which size to get the 60mm or the 70mm. will both fit stock systems?

 

I've had my TP on for almost 3 years with the spark plug anti-foulers with no Cel. I'd say $5 bucks and 5 mins of your time is far better then $40 plus shipping cost. Just my .02

 

which TP did you buy?

 

Go with Berk's Testpipe. It has a built in CEL fix. It's 63mm (2.5") and works with your stock exhaust setup.

 

i was going to then i found the invidia for 79 so i thought about that its 60mm

 

let me know what you decide and what works for you, i'm very interested in knowing.

 

My Invidia 70mm TP (bought from Evasive) came with a CEL fix Ive never seen my S's CEL come on

 

does having a test pipe turn your exhaust tip and bumper black?
