Roush Extreme Performance Off-Road Exhaust Kit #403936
The Disclaimer States, " ...be aware that this off-road exhaust kit may exceed the sound level ordinances in many communities..."

Well, it’s loud... and it’s deep... and it’s mean, but I’m not too concerned about violating any local ordinances. I can say with certainly that this is the best overall sounding exhaust system (axle or cat-back) available for the S197 model. I’ve contemplated purchasing this kit since January. I could have saved a lot of time, money, and aggravation if I had acted sooner.

I’ve personally own, installed, and experienced the following exhausts on the S197:

2007 Mustang GT-

Magnaflow #48019
Flowmasters #17410 (X2)
SLP Loundmouth #M31014
FRPP/Borla Stingers #M-5230-5GT

2008 GT500-

FRPP/Borla #M-5230-SGT
Flowmaster #817410
Mac Boom Tubes #BT2005

All of the aforementioned exhausts sounded good, but in comparisons the Roush set-up wins hands down in acoustics and quality.

Based on my experience, and due to the design of the exhaust system on the S197 (mufflers located past the axle), the louder the exhaust- the greater the drone/resonation. It’s a sacrifice that I wasn’t willing to compromise.

The Roush system is unique in that the resonators (pseudo mufflers) are located before the axle, thus providing volume while minimizing resonation. This set-up is significantly louder than OEM, yet the drone level is equivalent...

I’ve heard the Corsas (Extreme) and the KRs. I agree with the masses, the Corsas definitely do not drone, however, many say that the KRs don’t either, but I digress. While the KRs have negligible drone, I’d say it compares to the level of the Roush set-up, however, the Roush exhaust has twice the volume.

Installation: Unless you have access to "lift", installation will be a PIA. Removing the OEM mid-pipes was easy. While on floor ramps I lifted the body to create more space to maneuver between the body and the axle. Conversely, installing the Roush mid-pipes was difficult. The Roush system seems to be made of thicker grade steel and the mandrel-bends play havoc in getting them positioned over the axles. I actually had to temporarily removal the springs on the passenger side (remove the sway bar, shocks, and drop the axle) to facilitate installation. There may be other techniques, but this method worked best in my application.

Conclusion: The Roush system is not a loud obnoxious exhaust. It generates a "tuned" high volume aggressive tone with minimal drone. While no axle/cat-back system yields measurable performance gains, this system feels like the car gained a few hp/tq. It definitely sounds faster! My pursuit to find the perfect sounding exhaust has ended.

If you don't mind me asking, what did the Roush system set you back? I'm on my third system. While it is the best one yet, I'm still not satisfied. Right now running custom baffled Mac Muffs with dynatech headers and cats.

Sounds like you already have a decent set-up. Trying to find that perfect sound is addicting... Price? Here you go: http://www.stage3motorsports.com/pro..._Shipping.html

Nice cover!
May I ask what brand and where more are? :D

Ryan

[SteelTownStang]

Hey Ryan... Just saw pics of your new mods. The SS wheels look great.

The cover is the OEM GT500 Car Cover. Ford sells them for $399.00, but I've seen them for sale on ebay, as well as Shelby and GT500 forums, for much less...

[98saleen]

OK thanks.
Very nice! The guy I bought my wheels from on Team Shelby had a cover for sale.....but it was long gone when I asked about it! :D
