Well im tired of my XR1 and im looking for somthing that will perform without the noise and have a mellow tone. My mods are down below, I had thought about running about a 12" of straight pipe from my y-pipe and welding a Hushpower muffler with turndown before the axle..What are your thoughts??

I have quieted down my catless, Lt loudmouth I exhaust twice. The first time was with some Borla resonated tips, but they really killed the sound down to almost stock level so I removed them. The second time was with a pair of dynomax bullet mufflers, the shortest ones they make. I put one on each pipe just after the rear axle before my tips. Still had a nice tone but really took the edge of the loudmouth. Might want to try one in front or behind the borla.

A 22" case Magnaflow should give you a mellow tone at idle but a nice growl at WOT, I've heard them throughout the RPM range and really liked the way it sounds

what do you have after the xr1? is it dumped? my brother had his pipe coming out in front of the rear tire and that **** was loud!!! well 2 weeks ago he went to the muffler shop and had them run a 3 "tail pipe all the way back to the stock location and it is quiet down big time!!! it now just has a nice mellow sound to it, it doesnt sound nothing at like it used to loud!

Yea, the length of the tail pipe(s) will make a big difference My Gibson cat back was way too quiet until I removed the tailpipes that ran to the rear bumper and dumped it before the axle, now it's like a completely different exhaust, much louder!

I have always had good luck out of glasspack style mufflers. In particular I like Sweet Thunders in a 3" x pipe setup. I can testify that a dump before the axle leads to alot of in-cab vibration and drone at cruising speed. Experienced this on my T/A and a K5 Blazer. Im going to have the exhaust on my silverado dumped out the side in front of the passenger side tire. Im going to start with a Flowmaster super 40, and probably change to something else depending on how far I mod it.

I say go with a Hushpower or a big delta flow Flowmaster. The tube style Magnaflow would suit your needs based on the characteristics you are looking for and wont sacrifice exhaust flow.
