I installed the HKS Hi-Power today; then went for a sprinted 30min drive, the car sounds great, but the car smells like crap, smells like it has no cat. Is this smell normal? Or is this caused because of an exhaust leak? I checked and made sure everything was tight. How can I know if it is an exhaust leak?

Thanks.

 

Do not worry it is normal. You would hear and exhaust leak and plus an exhaust leak wont cause a smell. Drive the 8 and have fun the smell will go away

 

Probably just "new exhaust" smell as everything burns in. Last week I had some piping and a magnaflow muffler welded up to my stock catback pipe and it stunk for a day or two; no problems now.

 

Yeah that's normal it's just the oil and stuff buring off from manufacturing just drive it about a week and my smell was gone!!!
