headers w/HF cats and L99 muffters delete ?
 

thinking about mufflers delete , i know it's sound better than stock mufflers but didn't found any video with headers w/HF cats for L99 ? most clip for LS3 and some without HF cats !!

any clip ?

sub zero,
I search land and hard on this one, headers, h/f cats and res-delete and keep your mufflers. Add x-pipe in place of stock res = fairly wicked when you step into it, and very normal and no drone on cruise. If there is a negative at all, it barks hard on first start up in the am.

Hope this helps

thanks , it's not necessary to do xpipe with only headers and CAI , i feel little raspy with stock mufflers after install headers , so i wanna do mufflers delete to get a little deep tone but i don't want it to be too load.
