I just got my new off road headers (SLP) with the random tech y-pipe and the loudmouth exhaust. It is really loud.......Now I thought that the cats would quiet the sound....but it did'nt. But it still is great it sounds ready to kill

 

Any soundclips?

 

I had a similar set up (jet hot long tubes, custom catted y-pipe, and loudmouth), but personally I think it sounded like garbage. Didn't even sound mean, just obnoxiously loud.

 

no sound clips for now........I also have a cam so it sounds nice....I could see on a stock internal car how it could be like crap.....Nothin like a cammed LS1

 

I have the same setup too. I like the way it sounds..except when the engine is still warming up and your in the 2200-2500 rpm range. You get that "Wap" "Wap" Wap" sound. Once the engine is at operating temp..its painfully good to the ears. I'm interested in a new exhaust, but can't decide on what to get....ahhhh!!!
