I've just put on My Loudmouth and I love the way it sounds, but come header time I hear it will be fugly sounding. I hear an Xr-1 is the way to go, but I'm a poor college student so a $122 muffler isn't all that appealing . I was thinking about a 1 chamber flow or possibly these new Outlaw Race mufflers by Flowmaster. http://www.jegs.com/cgi-bin/ncommerc...16&prmenbr=361 What do you guys think? Will it kill the rasp?

 

The only muffler that has really been proven to get rid of rasp is the Borla XR-1. You could try those Flowmasters, but at $80 a pop.. what's another $40.

 

As long as you don't have LT/ORP, a bullet will make it sound decent, and they start at $19.99 or so.

 

OK you poor college student; if you can afford a Loudmouth and plan on getting headers, you can afford the extra coin for an XR-1.

you'll love the XR-1 ...trust me.

there's a good link for you http://www.javagator.com/z28/images/borlaslp/

 

yea there's not much baffling in the flow mufflers, seen them at the Super Chevy show. My buddy just put a XR-1 on his Camaro and he has Mac's with ORY and it sounds bad ***, he had a bullet on it and it was raspy as hell. I'd go with the XR-1.

You're gonna have to go back to stock ride height to get enough clearance to quit scraping. Springs in the back will help, but you'll still have problems in the front and potentially scrape your headers. My friend's 79Z28 has 2.5" true duals with flowmaster 40's and H pipe. The car has somewhere over 300k total miles and has been in the air and still has the original springs. It definitely sits pretty low and he had scraping problems pretty bad. He did get different offset pipes that tucked the mufflers up into the tunnel areas better, but he'll still scrape with speedbumps and large dips on the highway every once and a while with passengers in the back.

I suppose you're right, although I got the LM for 200 shipped . Thanks for the info guys, I suppose I need the steel packing in the Xr-1 to baffle the sound. Just out of curiousity, are there any other mufflers that would work? I know that very few have been tried, that's another reason why I wanted to try something different. You never know, the Loudmouth owners could've to me for my findings!

 

I had the LM and really loved it too, but when I put my headers and ORY on, I put a Moroso spiral flow in place of the resonator on there as well. It sounds really good, a little quiet when cruising, but is at WOT. Got rid of 90% of the rasp, I only hear it when shifting at 3500rpm.

 

I have been thinking about the FM insert for my loudmouth too, nt sure which one though... Would be nice to have one done to see how it sounds... anyone have a spare flowmaster setting around?
