H-pipe question - droaning concerns
 

Hey all, just a quick question.
I have BBK LT's, BBK Shorty H with hollowed cats, and a Mac cat back. It's hella loud, really droning, and getting rather annoying when driving.
My question is, if I replace the H that's on the car now, with one that has good cats...will it quiet it down noticeably?

or an X pipe maybe????

Yes the cats will aid in the noise level to a certain degree.
If you still had the stock exhaust manifolds,then the factory 4 catted h pipe will definitley help you out even more LOL!
If the catted mid pipe doesn't help,then you will need to look at a different cat back set up sine the MAC are chambred mufflers,and chambred mufflers like to drone.

Cats will quiet it down some but you may need to look at some different mufflers.
