I had my exhaust replaced some time ago for a stainless 2.5" HKS system with Cobra straight through back boxes. Sounded Well.

Decatted it - sounded better.

Now I have had the middle boxes removed so its straight through to the back boxes (which again are straight through).

Sounds extremely well, deep, throaty and LOUD.

However I have noticed now the right exhaust rattles, not the exhaust but it sounds like something in the engine making a noise?

The only other thing I have noticed is a little black smoke from both exhausts.

 

Any ideas?

I can probably record the sound as an mp3.

Is it like a flappy type of sound mate?

Jay, could be that starter heatshield rattling off the exhaust?

Is the smoking constant on tickover etc ? or is it just when you de-cellerate ????

Thanks guys, Im really not sure as Ive nbot been spending much time with the car now lately. Ill look into it and post results. But yes, I think it was a flapping type noise. Sounded like the induction kit coming out the exhaust. I may try and record it for you.

 

Thanks again
