I was wondering if htey had anything to do with sound. I am gonna be getting hte zz409 cam, LT headers, no cats and the hooker catback, I like the stcok tips better but would that have an effect on the sound?
how will that setup sound anyway?

 

Believe it or not, they do. I really can't explain how, but after I installed mine last dec. I left the tips off for a while since I just polished them and wanted it to cure. I took it out for a spin with just the pipes, noticed(and enjoyed) the sound, and came back. Later I put the tips on, did a second run through town (the cops here hate me, BTW ), and the tone did change noticeably. It sounded great. But I'm going for these tips here this summer:

Scroll down to the SS Camaro tip (center inlet). The twin tips look ok, but the factory flare tips have always looked the best, IMO.

 

did it sound better with or without the y-tips
