So I put on my hks hi power and when I floor it I was told it shoots greyish smoke. Is that just the carbon. And at idol it smells soo bad. Which what I was thinking it's normal for a turbo car to shoot smoke and smell bad?

 

Is it catless? have you had it tuned? Do you know if you're running rich?

 

You are breaking the exhaust in. When you first install an exhaust, you will blow smoke at full throttle, and it will smell like a burning smell. You are fine buddy. No worries.

 

New exhaust will smell like its burning. dont worry

 

The exhaust is used. But it running rich. I was just told it was Normal by ams so no worries.
