Next thing I've been working on is a traction bar. However before I could do that I needed to re-route my exhaust. I've been running duals, but with the traction bar I needed to clear up the passenger side. So I purchased a Spintech muffler that has dual 2.25" inlets and single 3" outlet.

I found out about Spintech reading some threads on Pirate. I'm very glad I did. It's a small company and they actually fabricated the muffler I ordered, it wasn't just sitting on a shelf. First off, I love the way they are constructed. I read on Pirate the muffler can really take a beating and after seeing it first hand I understand. Here's their diagram of the muffler internals:



The spiral baffles are called "spin traps". They also serve the strengthen the muffler because in mine there are six of those essentially connecting the top and bottom of the muffler therefore making it very solid. But it is still quite light.

The price wasn't bad either; I paid $112 with shipping. About the same price as the Flowmaster 50 series SUV muffler I was looking at. Specifically I bought Spintech's Sportman Street series.

It sounds really good without being obnoxious on the road. It doesn't have the drone I've experienced with FM 40 series in the past. According to Spintech, their mufflers out flow FM by a lot.

Here are pics of the install:



I pieced the exhaust system together using pieces from Summit. A few mandrel U-bends and some straight pipe. My only complaint is that the straight pipes were shipped "naked" so the ends were covered in packing tape. I know UPS requires it, but it was a bitch to remove. I obviously missed a piece which you can see in the picture of the tailpipe below:





Here's a video I just shot tonight. You can here in the drive-by it's actually pretty quite at cruise.
"Video of Spintech muffler, Sportsman -..."


I have some video of the interior sound levels, but I'll have to get it uploaded tomorrow morning because I'm on the wrong computer right now.

For anyone shopping mufflers, I found youtube to be very helpful. There are a lot of video clips of various mufflers and exhaust setups. Thats part of the reason I'm making these videos, so I can share the same with others. It's really pretty handy.

I have the traction bar all tacked together, but we ran out of welding gas. So I need to finish welding it all up, paint it, then install it. I'll get pictures and descriptions up once I have that done also.
