After a second muffler failure I returned both Ultra-Flo mufflers to Walker for a refund.
I finally got around to finding someone to TIG weld an extra 3" long section of tubing to the tailpipes so I could install some new 18" long case 3" Race Pro mufflers.
Mufflers, tailpipes, clamps and sealer ready to go.
The PYPES Race Pro mufflers are very compact compared to the old Ultra-Flo mufflers, about 5/8" thinner in profile so they offer a little more ground clearance. They're very lightweight too at only 12 pounds each.
I picked up this tube of tailpipe & muffler sealer from my local NAPA for about $10, I've already done several muffler installations
and it's only about half used-up.
Installation complete and ready to fire up.
The stainless band clamps are a huge improvement over the old U-bolt clamps I was using previously. They clamp more uniformly and don't kink the joints, making it easier to take apart in the future.
Fired it up and listened to the new mellower exhaust note. Still plenty powerful-sounding, but a little less noise than the Ultra-Flo mufflers. Much better, exactly what I wanted.
Tomorrow I'll take it for a nice long test drive, later on I'll post a video.
