Fabbed Up A New 4" Exhaust System
Here's a few pics of the new exhaust system I fabbed up this last week. I really like the way it sounds compared to the raspy true-duals I had. For now I ended up leaving the 3" bullets installed in the Y-pipe portion to help tame the sound of it but I might remove those later on. Don't have a sound clip yet but I'll try to get one after I fix the front crank seal leak.
Mocking up the 4" mandrel bends/muffler and tacking them in place. Getting that 4" pipe to fit over the axle was very tuff. It's got less than 3/8" clearance in every direction. I had to make the exhaust hangers fit very snug to prevent it from rocking/rattling against the car. Also installed a band clamp joint above the axle for easy removal. I was also very surprised how light weight this system is compared to a stock exhaust. All of the SLP catbacks are stainless steel which is very heavy. The Dynatech muffler is very light weight also..... I might end up changing the rear exhaust tip. It was hard to tell how far is was hanging down past the rear bumper when the car was in the air. I might end up tucking it up further into the bumper for more of a stealth look..... ? What do you guys think?

thanks guys. I got the mandrel bends from a local trucking supply house called anderson brothers (portland, or). They had a large supply of mandrel bends ranging from 3", 3.5", 4" and even 5" stuff. I got all the bends and 4' of straight pipe for under 180.00. The muffler was around 110.00/shipped from summit.

You would probably be better off finding a local trucking supply company closer to you. It would save you the shipping costs and then you can browse their warehouse to see exactly what you need/want etc... I know Anderson Brothers sells V-band clamps and stuff like that too. Sent you a link to their website...

Thanks Mark and Doug. I'm happy with the way it turned out and especially the sound. It's nice and mellow at idle and has a nice smooth/deep growl at upper rpm. Should have a sound clip this afternoon now that the crank seal has been replaced.
Mark, my intentions were to run in a Heads Up class this year, hence the full slicks. Unfortunately, I've been a day late and dollar short all season so I missed all the events. Just now getting all the gremlins worked out.

Mike, I meant to ask you what kind of welder you are using? I was looking to replace one. I looked at hobarts, linclon, but was leaning towards a miller. What do you think?
Also in case I failed to mention the exhaust sounds like it wants to eat a ford for some reason....
