I don't know what kind of car this is on or what year,all it Say's is 350 slp headers.this is what I'm looking for.

If I had to guess I would say it is an Impala SS lt1.

what do you think?

For what it's worth- I had the ATR's on my GN. Top quality, straight through design. Hard to compare sound between a turbo 6 and a n/a V8 though.

I have the pitbull on my car, I love the sound. it is quiet at idle, but roars at 3k and over. The fit was a bit off but the muffler shop that did the install fixed it in 2 mins. way better sound then the loudmouth with the slp lt's and cats

The exhaust is done but I don't have a sound clip since we are doing other things. I'll ask one of their guys to maybe post some impressions.
