Had the Street Legal cat back system on for 9 months. It served well but I just needed a little more rumble. Replaced the system with the Roush Off-Road cat back setup. The Off-Road has the same deep rumble but louder and I'm lovin it. Here is a picture from my gallery showing the difference between the two mufflers.

got any plans for the old muffler?

 

thanks for posting that comparison pic. i know there has been alot of questions on the size difference between the legal and the offroad

 

Took delivery yesterday from Woodhouse. The Roush off road is being installed as I type. I had called Midas, they wanted $200.00 Local guy is charging $75!! I am having him put on the tips, however I am going for 'the "murdered out" look so I may take off tips down the road. Anybody have experience with turndowns at the back? I know turndown just after muffler can be very loud however will I notice a difference with turndowns at the rear.?

 

You will hear it alot more inside. If thats the way you want it sounds like the way to go.

 

You'll need to re-route the piping out the back for the murdered-out look with turn downs. The Roush pipes are very visible from the sides.
