Thread: Mufflers

Tweet

I played around with building some a few years back for a few of our rock crawlers. I was really surprised at how simply most of the high dollar mufflers are built. I have a good friend here in town that does a lot of muffler work and has a lot of flow testing equipment for them. After doing some research I found that they are very easy to build and in some cases I could achieve a good sounding muffler with the same or better flow characteristics than the brand named mufflers In some really small boxes. A few of my creations.

I'm a Corsa fan, but since they discontinued their black box and red box mufflers you can only get them used. It took me 3 years to find 3 mufflers and I got lucky and met the man who runs their production line. He had them behind his desk new in the boxes.

Other than that is comes down to dimensions and the material you wish to use. There are far more choices if you are willing to use Mild steel.

The 50 series Flowmaster is what I went with as the 40 series is just too loud. I didn't install an h-pipe, but would if I had the exhaust to do again.

Roger, I posted earlier but found more data on mine to share. When I had my Fairlane duals put on I was going to go with Flowmaster but my Muffler Man said that the VX series muffler made by AP Exhaust Products was better and cheaper. So I went with his suggestions and have not been disappointed at all. Total job was $450 and that's from the header pipe to the rear bumper. There is lots of info and comparisons to google but here's a couple of testimonies from a Vette Site. VX Mufflers vs. Flowmasters - LS1TECH

Of course you know that after you make the change a posted audio is REQUIRED???

Good Luck,

Thanks for the compliment, always much appreciated

I put super 40's on my chevelle, flowmasters, with 3 in out the back. Sounds awesome around town, drives me crazy on the rd at 60 mph. I think if the floors had some better insulation it would help.

Your 60 mph problem sounds like it could be a tailpipe problem. Did you take your tailpipes all the way out the back, or at least to the outside of the body, to exit away from the underside of the car or are you running short pipes that end under the car?

HotRods need side pipes and loud, biased not a humble opinion.

Some are too loud, top fuel comes to mind, dawn mickey mouse ears, will knock that down a notch. The pummeling of the body the sound waves administer will make that up.

Yeah, got one of those, but not the pipes that carry the sound near the back of the door. Ya' don't know loud until you run open lakes pipe megaphones that end at the leading edge of the door - near physical pain at WOT nearing red line
The one I'm doing now will have a more subdued sound, with pipes going out the back and an auto trans, so Mama can enjoy it if she chooses, but thanks anyway....
