I've got a 97 4.6l bird. I want to give it a little different sound and less restriction. I found this exhaust company. Anyone ever use this stuff?

I have a 2000 Mustang GT with a 4.6l and I have done the exhaust in that with O/R x pipe. This setup looks almost the same except the rear pipe setup. I just want to know if this worth the money? Any problems? Better options? Any info is great appreciated.

Read the thread Darren linked to. There are many videos, including two that I made, in that thread.

I was reading there was issues with everything fitting correctly? have they fixed this issue? I want to pull off stock and put on new piping.. I don't want to deal with modifying anything.

My order was initially fulfilled with the same style kit that people were having issues with. Rather than spend more money to have an exhaust shop modify it, I sent it back and let them make it work for me. As long as the product they send out from now on is the same as the one I ended up with (see pics near the end of the thread), you should have no issues pulling this off in your driveway with nothing more than a socket set. I actually need to add another picture or two now since I've actually finished the install. :)

I'd drop them an e-mail first to ask if the'll be sending you the updated version of the piping. And be sure to ask that the front hangers are in the right spot (I had to bend one of mine slightly).

I can't say I noticed any improvement in economy, but I can say I felt a definite seat-of-the-pants improvement in performance.

I'll take a snapshot or two in the next few minutes and add it to the other thread.

Let me say, you really don't have to spend that much money to get a very nice exhaust system. For a reference point, broader performance did a CFM test on several of the most popular mufflers: broaderperformance.com/muffler_flow_tests.htm
Here were the flow results: (Independently tested cfm flows of the more popular mufflers, glasspacks and resonators @ 15” wc:
2 ½” diameter straight pipe 521
2 ¼” diameter straight pipe 365
2” diameter straight pipe 283
2 ¼” diameter tailpipe 268
2 ¼” round glasspack- no louvers 274
2 ¼” round glasspack- with inward punched louvers 133
2 ¼” round glasspack- inward punched louvers/installed backwards 141
2 ½” inlet/outlet Dynomax SuperTurbo 268
2 1/4” inlet/outlet Thrush CVX 260
2 ½” inlet/outlet Flowmaster 2-chamber 249
2 ¼” inlet/2 ½”outlet Cherry Bomb turbo 249
2 ¼” inlet/outlet Flowmaster 3-chamber 229
2 ¼” inlet/2 ½”outlet Maremount Super C (OEM Replacement)149

DYNO TEST
All mufflers were dyno-tested on a 355-cube SBC with 10.0:1 compression, Air Flow Research 190 aluminum heads, a CompCams 292 hyd. a Victor Jr. intake, a Holley 750-cfm double-pumper, and 1 5/8 Headman headers.


MUFFLER HP TORQUE 2,500-6,000rpmAverage
Hooker Competition 397.4 381.1 286.8hp/351.9 lb-ft
Thrush Boss Turbo 407.1 384.9 292.1 hp/357.5 lb-ft
DynoMax Race Magnum 409.5 394.3 298.8 hp/366.9 lb-ft
Flowtech Afterburner 409.7 391.2 294.8 hp/361.7 lb-ft
Thrush Glasspack 409.5 389.8 297.7 hp/365.3 lb-ft
Summit Turbo 411.5 386.3 291.5 hp/357.4 lb-ft
DynoMax Super Turbo 412.7 387.2 292.6 hp/358.6 lb-ft
Hooker Super Comp 413.8 387.2 292.8 hp/359.0 lb-ft
Summit Fully Welded 415.4 390.7 295.6 hp/362.4 lb-ft

The one thing that should be recognized as a common factor, is the best flowing units are of a stright through design- Allied as an example has been building glasspacks (or resonators) for 40+ years, they flow as well as any of the high performance mufflers yet cost about $40 each and available at any muffler shop.


Ultimately, it is the quality of the material and the installer which 90% of the time leads to a successful installation. I would like to also emphasize that it is not necessary to spend a fortune on a muffler ($100+) or system to have an excellent sounding, performing and long lasting result.

Yes...and look at the numbers that the Summit brand "fully welded" muffler did...surprising since they are usually not the highest quality, but seemed to make the most power, and were not the loudest...but between those few db, you probably could not really tell.
