Take a look at SLP Loudmouth. Also a straight through design no restrictions.

I have B&B Bullets with stock everything else, and absolutely love them. Have had others, including NPP, love the B&B Bullets the best by far ...and they look the best too.

Highway speeds, which are almost always is great too, not too loud at all, but punch it and it does sound fabulous.

Just the catback and it sounds just like the Corsa video I posted. Plus the fit is awesome! All four tips are almost perfectly spaced and centered which covers the exhaust area on the Vette nicely. I went with the black diamond finish just like the one in the video.

Round tips. No sound clips, but girlfriend loves them. Install is the same as any. On a lift is best, but if not, lift the rear of the car. Drop the rear sway bar, and wiggle the old ones off, and wiggle the new ones on. The tips are 4" and look great.

I have ridden in a C6 with this exhaust that had headers with cats and I can tell you it was much louder. With my stock exhaust manifolds and stock cats it sounds just right to me. Quiet enough on the highway, not too loud, driving through the gears sounds great, nice and aggressive, but punch and it roars really nicely.

Axle back, not cat back...Bullets and Xtreme are probably the loudest and look best. SLP and Borla are a little behind but both tips are hideous.

SLP Loudmouth 1 and B&B Bullets are the loudest by far.

I went with B&B PRT axle back mufflers with 4" Black Oval. Love the sound and this is the third Vette I have had with them. Had Corsas on one of my Vettes and while nice, not as nice IMO as the PRT.

Biggest sound dampers on the C6 is the stock cat's/OEM manofolds. Changing out to long tube heads, and high flow cats makes the most tone difference in any muffler system down line.

From there, it becomes a matter of tone that is coming out of the pipes.

Yes, you can straight pipe, but lets face it, your vet is going to sound like a trash truck going down the street.

For me since I am a huge V10/V12 sound guy, the Corsa systems has the perfect note of that type of rasp/tone, without any droning.

From there, you get into Borla system, that have that more glass pack sound of American muscle cars of the past without droning (the new models), but it is verging on sounding like boarder line track truck/straight piped truck.

Then you have the rest of the systems, and let face it, it no so much a matter of tone (not longer in the tech rasp kind of tone), but just how bad the system is going to do drone instead.

If you are looking for a BB or Flowmaster system, then should be able to pick one up on the cheap that someone just ripped off there car almost brand new, since they could no longer live with the amount of droning they produce.

To be blunt, if all you want is loud, then either straight pipe the system, or just drill and pull the fiberglass packing out the stock mufflers. If on the other hand, if it the perfect tone, then know know why the preferences are either Corsa or Borla, since neither of these will drone.

This is my experience that SLP Loudmouth is beyond the shadow of a doubt the loudest God D@mn exhaust system offered. It is not a muffler system but a "LOUDENER" system I swear.

Ya, by loudest I didn't mean the absolute loudest possible, this is dumb and i dont want to **** everyone off. I want a clean, Corvette-like loud sound. Because I hear so many Corvette here who are very quiet (mine included) and I hate it. We have a 6.0L beast that only want to scream and all we hear is nothing. This is the essence of my question.

Looks like the BB Bullet is still ahead, but is the BB Bullet loud only because there is no mufflers attached to it ? Or is it also because of the shape and the material used in the pipes ?




VS those Corsas who still have mufflers :




Is this why the BB Bullet is just louder, beacuse of the lack of mufflers ?

Thanks again.

Oh wow, I just saw that the SLP Loudmouth (650$) are almost half price of the BB Bullet (1200$).


SLP Loudmouth has the lead right now, I love the sound aswell.
