Mine seems to have cured all the sudden. Maybe it was packing oil from the exhaust but man if so it took a long time to burn off compared to other cars i have owned.
I have noticed this morning a bit of white smoke out the left pipe(mind you this is a kooks muffler delete, res delete system so both sides should see it i would think. Just noticed it following getting all the hardware on the car. It could be condensation but it was following a drive long...
yea i got mine installed fine just a lot of lube and pushing and twisting. Just would have been nice if Kooks did not use the one size fits all approach lol. However a good quality system with great clamps etc for a really good price and made in the USA.
