I have had a few motor guy friends, tell me that they have seen clogged cats from mods is causing some piston and rear main seal problems....a
My cats seem to be rattling a bit, and temp reading appear to show a problem..but no codes related to the cats are being thrown...
My rear main also blew while passing traffic, on a grade...
I am going to look into high flow cats and some motor work, and a good catch can vent system..
Lilbean1982, How much louder is it without the cats?..I already have the Borla attack, and it is loud enough (sez the wife..lol)
