New SLP catbacks?
were to be shipping in the first week of July, but just want to see if
anyone got theirs and what do you think of the sound and performance.
One SLP's site it sounds louder than Magnaflow's catback. I like the quad tips
personally...If Magnaflow would just make smaller tips it would be even better.

I wonder if they have a 'no tip' option so I can re-use my corsa knock offs.

I like it, but wonder how well it flows and how it sounds compared to a magnaflow setup.

The Best V8 Stories One Small Block at Time
It sounds truly awesome compared to my old dual-dual setup. Real musclecar sound with no rasp at all and no drone either
The sound is much more louder and deeper than the dual-dual.The only downside was to fit it correctly. Everything was OK, except for the tail pipe on the right side. It was not centered, lower than the left one, and it exited at an angle of 15 degrees toward the exterior

We tried during over an hour to fit it right but there was nothing to do
At the end, we had no choices left, but to cut the pipe at four places and reweld everything to the right angles. A real PITA I can assure you 
But once everything was done, and we crancked the engine, all of this was a thing of the past. The sound of that catback is really awesome ! ! ! ! Now I have an LS1 that sounds like a true V8 should do

The system is installed on a Formula Firehawk. At first, I feared that the mufflers will stick out too much from behind (since my car don't have rear skirt like the Trans AM do) but it's OK. They are not really visibles with the dual-dual tips.
Overall, I'm really happy with my exhaust swap. Sorry, I don't have pictures or soundclips yet, but I will try to have some in the near future.
Eric.
half the air goes thru the muffler then out the driver side pipe. But the baffle also splits the air and directs it to the passenger side pipe. I'm sure it's not a big deal but, the SLP system has two staight thru mufflers. The flow doesn't have to make any turns or anything. It cost alittle more, but i just hate how the magnaflow tips look...yuck!! I like the dual-dual tips on the SLP system. But either system is awesome. I like what Blue Hawk posted about the sound

That's great that it gives the LS1 a deeper tone.
this new powerflo system looks kinda gay. i just don't like goofy looking mufflers on the tailpipes. it will look stupid seeing them hang down like that IMO. might look better on the ta because the bumper will hide it

the muffler. Mustangs for instance have their tips hooked up to the muffler and as much as i hate mustangs i never gave their mufflers one thought. Cobalts, G6's, and probably the new Camaro will show some muffler. Besides the further back the muffler is the less it restricts flow. Plus the tips themselves will hind most of the mufflers especially since it seems like SLP have them tucked up pretty good. But Brien is right...pics would help on both f-bodies.

But it looks like the muffler is 5 inches tall. so the only part you might see
is just the bottom of the muffler, but if you can see it from the side that would definately look like ***. Hopefully there will be more pics of camaros
with the catback so we can all get a better idea.
Actually, you can see a part of the left muffler because it's closer to the tip than the right one. The right muffler is almost invisible.
Pictures 3, 7 and 9 have been shot with the cell phone being only a few inches above the ground.
Edit: This is a Formula Firehawk, not a Trans Am. So it should look exactly like this on a Camaro, and the lower skirt of the Trans Am would probably hide everything from every angles.
