Borla XR1 Muffler

[Jason in DLH]

If anyone is doing research on mufflers I love the Borla XR1. My wife says it’s too loud, but have had compliments from car enthusiasts. It’s a straight through design with perforations that allow the noise to enter a larger cylinder at cruising speed for a great sound. The great thing about it is that when you mash the gas the outer cylinder “fills up” and actually increases exhaust velocity as the exhaust simply cannot enter the outer cylinder anymore.

It is a bright stainless steel... I’ve just never cleaned it.

Do you get fumes inside if you're sitting still while running?

Nope...no issue.

they'd probably be happier with you starting truck up.... rather than dragging a floor jack down the street though

100% my favourite muffler to date, XR-1's should be on every LS based vehicle in my opinion!

I have the XR1 on my yukon this is what it sounds like from inside, it's not all that loud in my opinion

I think it sounds good.

I like it much better than the flowmaster I had on there, at WOT the flowmaster sounded like shit

I think I want to quiet mine down some.

 

[Doubeleive]

did you remove the cats? I have cat's and no headers only thing that was removed is the last resonator, just has the borla and k&n blackhawk

 

[gat0r]

they both sound good

I listened to countless youtube videos of other 6.2l. I'm a big borla fan. Had a borla catback on my ram. No drone. Sounded pissed off when you started it up. Seems that some borlas sound good and others not so much. Could be the quality. Hard to judge an exhaust on youtube. There are not many videos around, but a muffler I really liked what.i heard was a gibson muffler.

What kind of flowmaster did you have ? Reason i'm asking is because i have a super 10 sounded ok until i put headers on recently . Now I have a bad case of the ****** sounding exhaust clap!

I Believe it was a 40 series 2 chamber single in 2 out, sounded ok driving normal but if you floored it then it sounded like crap, like a blown out balloon letting air out

That is exactly my problem. Well i just purchased the borla xr-1 . I hope it lives up to all the hype.
