i have a 96 a4 [v6]
my cat is messed up and my car is making annoying rattling noises.
whats the cheapest way to fix the problem? would it just be to remove the cat and get a test pipe? would throwing on a random cat from anywhere/any car work if i was worried about getting pulled over? i don't care if my car throws a cel i just want to fix the annoying noise asap for cheap

just gut it then. It won't be a s good as a test pipe though. Test pipes are pretty cheap on the other hand. About 170 shipped. Much cheaper then a cat.

well since he is V6 i don't know(at least i haven't seen any) if there are testpipes for him..

my buddy rocky gutted his cats.. his car runs great, faster too..

the only problem is that he throws a CEL all the time(but im sure the antifouler mod would work for you) and emissions

gut the cats or get HFCs

you don't want to gut the cats on a v6. they have up and down stream O2 sensors...

no cat=bad O2 signal....

bad O2 signal=poor performance and POOPIE fuel economy.

your choice tho...
