How do i determine what size test pipe to go with? I already have a magnaflow exhaust which i think is 2.5" pipe. Would i benefit going with a 70mm or 63mm? I also want it to have the cel fix. Any opinions?

 

With the diameter of your exhaust I would stick with a 63mm TP. Any brand will do so just go with whats cheaper. You will just need two spark plug defoulers from Autozone for the O2 sensor fix. Just drill one of them out to fit the sensor in and then screw them together and you are good to go

 

I have one when you're ready to buy.. w/ the CEL fix too.. Mine's never came on w/ it in use..

 

the same diameter as your exhaust

 

i have a BERK 63.5 mm if you want it, also with CEL fix. PM me for info.

I only had it on my car for like 400-500 miles, then i went with a 70mm Exhaust and switched to a 70mm TP.

 

 

The same, or smaller. However do NOT go larger.

 

I agree get one that is the same size as your exhaust.

 

I would go with a 63mm TP for a better flow.

 

Stick with the 60 or 63mm test pipe with that exhaust.
