was wondering if anyone was running a test pipe on a 2200? does it throw a code? can a o2 sensor spacer resolve the problem?
Yes, It will probally set a code. you should run a high-flow cat though. It is a federal offense to put a test pipe in place of a cat and the low HP gain isn't worth it.
Did I mention I drive a 2000 Lumina now?-----wigm-tuners.org member
I went from a 2.25" test pip to a 2.5" highflow cat and 2.5" reasonator and the butt dyno says there is a lot more power there...
