Has anyone had or have these mufflers on a LS1 or anything. I am very interested in these but would like some input.
How do they sound, are they worth the money, anything at all .

 

Do you have a link to them on the net cuz i have never heard of them.

The only place I have found to buy them is LS1 speed inc. Just type in ATR in YAHOO and you will get ATR'S website but I couldn't find mufflers only just cat backs.

Here is a sound clip I found all it Say's is 350 with slp headers ,I don't know what kind of car it is or even if it is a LS1 or what. If I knew is was LS1 I would most likely buy these mufflers.

If I had to guess I would say this is a IMPALA SS LT1



Let me know what you think.

 

I believe a lot of Grand National owners like them.

They are great mufflers, kind of a best kept secret that not to many F-body guys know about. I currently have their catback on my Turbo Z28 and also had it on my old nitrous long tube combo. Sounded great with either one, refined at Idle and a beast wide open.

 

I just put a set of ATR mufflers on my car, they might be Pit Bulls, I put 3" duals on the car with a 3" x pipe. I used to have a louder setup but it got old.

 

Sounded pretty good on the clip .
