Have you looked into the moroso spiral flows? I am running them on my dumped x-pipe and gives the car a very deep roar. Not sure how it would sound off the headers - I would image awesome!

I have a dumped moroso on mine and i HATE it. I will be putting an xr1 on mine when i fix it or a borla or corsa catback.

My friend had Moroso spiral flows on his 383 car. Sounded loud as hell but sounded like **** if you ask me.

I have heard them on many cammed LS1s. They sound great, I don't think you will be dissapointed.

I think they are some of the best sounding mufflers out there.

I've got a 3.5" XR1 in my garage I'll be putting in my i-pipe along with longtubes. They're pretty much hollow minus two louvered baffles that run parallel to the muffler body... I can get a pic if you want

I like Schoenfeld race mufflers. They are called mufflers so they meet requirements for "must be muffled" race cars but, they do absolutely no muffling IMO and they are only about $15 a piece.

One of the Texas guys, (blue SS) had them on his(i think)..He's been at the Shootout the past couple years..kinda looks like Taner's car..I can think of his SN. Sounds pretty good though.

I did a bunch of research on mufflers and I chose Borla Pro XS. They have the absolute best balance of power, sound and flow.

They make within 2hp of the wide open mufflers that make your ears bleed, have an awesome LOW evil throaty tone. In fact they made more AVERAGE HP (which we all know wins races) than any other muffler they were compared against.

The spiral flows sound amazing on some combos, but they are a huge restriction. There is a thread on here about a guy losing 70hp through spiral flows...

So, I vote Borla Pro XS. They outperform the XR 1's and sound better / deeper.
