Best size test pipe to fit on OEM exhaust
Hi
Did some search but couldnt find any info regarding the question, what is the best test pipe to fit on oem exhaust/headers? 63.5mm or 70mm?
When I say best I mean, for air flow and power.
Thanks

70mm invidia test pipe will work. I just installed mine with no problems. FYI, they have a version with the "CEL Fix"... it doesn't work, so just get the regular version and get a o2 sensor spacer to keep the check engine light off.

look for a thread started by Gernby, he's done lots of tests on this and a 70mm won't be as good for a stock exhaust.
