I got my replacement set of megan racing test pipes because of a resonator problem in the first ones. Well they stank of oil when i opened the package, so i figured they would for sure be smoking/stinking for a few days until it all burns off like my first set. well its been about 2 weeks, and they continue to billow smoke when i give it good throttle or when i pop the clutch comming to a stop a big cloud will appear in my rearview, what could be causing this? i checked my engine oil, and it appears fine, so it doesnt seem to be related to the engine. My coupe is a daily driver too, so its had many miles since the new swap. any ideas?

 

i dont think their is anything wrong with your car. test pipes make your car smell like a snowblower and kill the ozone layer. its their job to spit out fumes. not sure why you see a cloud though, i dont think the smoke should be that thick. maybe it was just steam.

 

you should definitely have it checked out
