Default Anyone have or heard the ATR Cat-back Exhaust???

I've seen this system for sale at through a few different places but no one seems to have it. Anyone here ever heard it or know why no one is buying it?

I haven't seen one in person for the f-body, but I had one of their systems on my GN- absolute top quality. The muffler on the GN syste was a straight through design.

My brother had it on his SS, no cats w/Hooker LTs, probably one of the best sounding mufflers I have heard. Not obnoxious but a nice, controlled roar at WOT.

ATR products are very high quality and well engineered. I cannot speak for their exhaust, but I had a bunch of their parts on my Syclone.

I have one with Hooker LT and ORY. Nice sound and the mufffler is a straight through design. It is about as nonrestrictive as they come. The quality of the systems is great. I have had it for 3 years now and not had any issues. The install was very easy and all the needed parts were included.

I would recommend this cat back to anyone.

Steve, how does it sound at idle? I want something pretty loud but I plan on adding headers this winter and don't want the dreaded rasp (which is why I'm probably not going to go with the loudmouth).

If anybody needs their number it is 803 972 3800.

This is from an old catalog I have for GN's.

I had one of their catbacks on my GN years ago. Top knotch system.

It is not that loud at idle. It sounds a little louder than stock at idle. Now when you get on it is a different story. It is very loud at WOT or over ~3500.

This was pointed out by a cop one night.

All in all I like the way it sounds. My wife thinks it is a little too luod.

I have one on my SS. Very free flowing, they have run 9's thru this exh. It is very quiet at low rpm but opens up after 3000. it is all 3 in int pipe, tailpipe and muffler.
the exh flow straight thru the muffler and out the dr side tailpipe. the pass tailpipe does very little as the exh has to go thru the baffles of the muffler to get to it. It needed a bit of trimming to fit with my headers as all cat backs would. now I love it.
