      That does sound good, but not smart.

      A local club member just put an SLP Loudmouth on his GT. It completely eliminates the mufflers behind the bumper with straight pipe & a set of tips. It sounded good as there are the cats & 2 sets of resonators in the mid pipe that kept the sound level reasonable.

      He is installing headers this weekend though, i am curious to see if that will be overkill.

      Still the stock system for the rest? Ie cats, and resonators? That'd sound pretty interesting...

      This is mine with just a twin 3" exhaust and also the stock HSV 4-1 short headers.

      Did your exhaust replace the entire mid pipe? Were the rear mufflers replaced as well? I think yours sounds good.

      In our club we have a the G8 which sounds good so far. My buddy has a GTO that is just obnoxious (headers & spintech mufflers). Then there is the 4th gen that trumps them all (headers & dynomax race bullets).

      I was surprised as well, the midpipe is completely untouched. The only drawback is the Loudmouth is expensive. Like $300+ for just a couple bent pipes and tips.

      Ill have to see if we can get some vid after the header install.

      Shane,

      Mine is a complete replacement from the OE cats back. So it goes from the cats to twin 3" into a cross over pipe and then two resonators and into two mufflers as it exits.

      Not sure how the G8's are but the HSV has headers rather than a cast exhaust manifold, so that does help to open up the sound a bit

      Cheers
      Brett
