Roush AB question!
Does anyone know or have proof of the roush axle backs giving any whp gains?? Just curious
I have heard the they give gains of 5whp to 8 whp. I'm skeptical about this

No HP gains but lighter than stock and the gt500's. I just preferred the gt500's without resonators better. It is personal preference. Both exhaust a/b systems are great bang for your buck

Hmmm not sold on hp gains from axel backs. Until someone shows me a same-day dyno with a gain I am extreamly skeptical...
That being said, the butt dyno most likely will see a gain simply because of how much better the car sounds!

According to Roush engineers your statement is not true...
Description:
Your Mustang Exhaust will never sound better.
The ROUSH® 2011-2012 Mustang Exhaust Kit with Round Tips is a innovative new exhaust system from ROUSH that features a open-chambered design muffler, as opposed to conventional fiberglass-packing.
The result is a exhaust for the Mustang that delivers a unique and less inhibited sound, increased longevity (there is no fiberglass that will break-down with time) and increased air flow for increased horsepower and torque by increasing airflow and reducing back pressure. Another added benefit of this system is the lack of the in-cockpit boom normally found with performance exhaust systems at cruising speeds.
Not only does the ROUSH 2011-2012 Mustang Exhaust sound good, it looks good as well. The round tips are made from high-quality 304 stainless steel and are finished with a chrome flashing process.
Conventional chrome plating uses layers of bonded chemicals to achieve its shiny appearance, which are susceptible to cracking and flaking especially when exposed to high temperatures (like exhaust). However, the chrome flashing used in this system is bonded micro-porously to the metal surface, and is as a result impervious to cracking from localized damage. This method of chroming is also resistant to heat color change.
The mufflers and inlet pipe are made from 409 stainless steel for increased durability. This kit carries a 3 year limited warranty.
This Mustang Exhaust is quick and easy to install and uses the factory hanger mountings, so you don't have to fabricate your own. This kit also features new OE-quality spherical clamps for a better fit. This kit has no negative effect on emissions.

I haven't noticed a difference in power. When I was talking to a guy at Bama he said they didn't give any gains until you go cat-back or headers. Only difference I've ever noticed was the sound got deeper once the CAI went on. Plus the tone is different between street and performance tunes.

No numbers, no dynos. Yeah, I'm totally buying this creation of marketing hype as fact.

Besides that, anyone that has been around for cars for any period of time understands there is not any major restriction in the mufflers. There is not room for substantial flow benefits due to swapping one mufflers out for another.
