I want to know which ones give the best performance and the deepest sound, and is droning a problem? between BASSANI & BORLA catbacks, between HOOKER, KOOKS, and SLP longtubes.

If you have suggestions of better exhausts, do tell.

 

For headers, you can't go wrong w/ any you listed. However, if I had to do it again, I would do Kooks and use locking header bolts.

As for cat-backs, I can't comment since I haven't heard what our cars sound like w/ the ones you listed.

 

Can't comment on the catbacks either as I have little experience with them. All those headers companies a great to choose from so nothing wrong with those. I do hope your car is a manual.
