ran one on my car for some testing...

It sounded very sweet! Very deepend note, but much quieter than the dynomax bullet that it replaced.

If I ever put a muffler on mine thats what I will be getting.

I was considering getting dynomax mufflers for my dual exhaust project. Are the Borla's that much quiter say in a 3 version?

I have used the same borla XR-1 3" in 3" out on my car with the twin turbos and now with the stock manifolds and no cats and it keeps that car quiet and sounds great with no rasp!

I'll try to remember and ask for sure, next time I'm up at MTI.

I have true duals, 3", with Dynomax bullets, and it's too damn loud with my 422ci.

I have been looking into a set of Borla XR1 mufflers, these ones:

http://www.borla.com/xr1.sportsman.oval.mufflers/

I know a local guy selling two used ones off a race car, center inlet/outlet 3". The mufflers have a lot less height than traditional muffler.

Is that what you tried PaiN?

I'm running the 3" in/out 5" round XR1 in place of the "resonator" on a Loudmouth. I think it has a pretty good tone to it. For those with duals a pair of the oval XR1s would probably clearance better and have a good sound.

I would run two of them into dumps. I hope it's quieter than the Dynomax bullets.

Did it kill the rasp?

I was thinking of using one in the I-pipe to kill the rasp of my grot ORP.

PSJ, let me know if you try this. I wasn't wild about dynomax mufflers when I used them in the Y-Pipe of my MAC ORP.

another alternative to the XR-1 is still in the dynomax crowd except it is the welded ROUND muffler and not the bullet

that muffler actually MUFFLES....lol compared to the bullet and its only $60 compared to the stainless borla which is about double

Ragtop, the XR1's that I am getting look like regular mufflers... Just smaller and different internal design. I don't think you would want to put them in a ORP.

The LS1 Motorsports turbo car ran an XR1 for a while. At "CyberBrawl" it sounded awesome during Tech. Car has changed a bit since then, don't know what it's currently running. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Ok big question for you all, I have the new Grot 1 7/8 headers with ORP, with a Loudmouth Exhaust, I was thinking of putting the XR-1 in place of the resonator, do you still think this setup would be too loud?? I'm majorly torn between doing that and just swapping out the whole system for a Hooker. Thanks all.

It will still be loud, although the 16" long bullet should make it noticably quieter than the loud mouth.

It would be too loud for me, but I like a quiet exhaust.

Thanks for the reply Ragtop, I'm actually going to weld a Sportmans XR-1 muffler in the rear of the exhaust and swap out the resonator with a straight through pipe. I think this setup will be tolerable.
