$145 Axle backs!! *pics*


Recommended Posts

So I just cannot see paying $400-800 for a set of mufflers! I had a couple 180* 2 1/2" bends left over from my last turbo build so i decided to build a set of axle backs for my Shelby:banana:


Like I said I had a U-bend left over so I didn't have to buy one, I took it to a local muffler shop and had each end expanded before I started so it would slip over the stock exhaust tubing. I then ordered a set of Flowmaster single chamber knock offs from ebay, I used a set on my Camaro SS and loved the sound so I thought for the price and quality I remembered why not try them out.

The PAIR of mufflers on ebay were $49.99 plus 14 bucks to ship.. I bought a 4" stick of 3/8" round stock from Lowes to make the hangers, ($5) and two feet of 3 1/2" Stainless steel tubing to make the tips (i polished after cutting) from Columbia River mandrel bending for $14/ft. plus 10 bucks for shipping.. I also picked up a set of stainless u-bolt style exhaust clamps from autozone and i had some black high temp paint already. I have a small wire feed welder as well as a large tig welder and a few other fabricating tools so i cut, fit and welded up a very nice set so axle backs for a LOT less than any other set out there. Not knocking any of them just cannot see spending that kind of $$ on something that does nothing but sound. Ill post a sound clip tomorrow when there is some day light.


Heres a price break down..

Mufflers- 63.99 shipped Super flow 1 Chamber muffler Race 2.5" free flowing : eBay Motors (item 190372293555 end time Feb-20-10 16:25:14 PST)

180* Bend $24 shipped (i think shipping was like $10) 2.50" Mild Steel, 3.75" Radius, 180 Degree Mandrel Bend Columbia River Mandrel Bending

2' of 3.50 $40 shipped 3.50" OD, 16 Gauge, 304 Stainless Straight Tube Columbia River Mandrel Bending

3/8" round stock from Lowes $5

2 Exhaust clamps from autozone $13


I could have built them entirely out of stainless but we dont have a lot of moisture here in the desert and when it snows they dont put road salt so rust isn't a big issue, also i would have been about twice the price. The paint will keep it from rusting any ways... Enjoy..


Heres some pics, vid will come shortly

Welcome to Team Shelby!


Very innovative! Nice job man. I feel the same way you do about the prices of the mufflers these days. In the 90's I bought a set of Thrush Turbo mufflers for my '72 that cost $40 and sounded great! The whole custom aluminized dual exhaust with H-pipe cost me $350!
