SLP Loudmouth FTW!!!
The looks (dual/dual slash tips or single 3.5 in slash tip on either side)
The sound (very deep rumble and LOUD)
The gains (yes...with an added y-pipe, you can feel the gain)
Price (does not cost you what Magnaflow or Borla will run)
IMO, there's nothing better...just my .02
And Mindz, I had the Loudmouth on my 02 Z28. It's just the SLP dual dual on my current SS now. Sux...and I'd spend the money in a jif for the old set up I had, but I'm saving it for the next SS.
