Absolutely beautiful job. Congratulations

How did those new seats fit?

Installed some J-pipes. They help with exhaust drone significantly!

Please explain the j pipes, are they capped ?or have some special end?

They're capped. What happens is sound waves come into the pipe, then are bounced back in an inverse pattern - which cancels out the noise. Reduces drone considerably. There is a formula to determine what length your j-pipes should be, based on what hertz range you're getting the loudest noise. An easier approach is to order these adjustable ones from Solo Performance. Then it was a little trial and error - loosen the clamps, slide them out 1/2", test drive, repeat.

Very nice, i had just read about that method the other day. looking good!

I was about to mention Solo - but you already did.

My buddy has those on his 2010 Camaro and they sound damn good.
