I ran a true dual set up with Flowmasters. Sounded ok
When I took out the 4 stock cats and put 2 high flows in,, it was 2 to 3 times louder.
I'm not running the magnaflow cats though.
My cats are much smaller then the maggys.
I have Bassani cats,,,but they were very expensive!

I'm in the same boat, but I'm looking at doing a Line-X Xtra coating on the bumpers and rocker panels. I've been getting a pretty big range of price quotes though. I'll let you know how it turns out if I find a decent place.

Here in Delaware the only test they do is plug into your computer. If no codes come up, your good to go.
I have all custom tuning and my tuner takes care of any codes.
I think he has 2 of the O2s shut off and bypassed.

ok cool
I live semi-close to you anyways, Wilmington, so ill see what I can find out as well and if one of us finds a really good deal it wouldnt be that big a deal to drive the extra distance. Its just about a 2 hour drive, if that

any gains/losses in the HP/TQ department or is it strictly for sound?

i like my MBRP exhaust, but it could be a little louder. i think i lost a little low end tq, and don't want to lose anymore with the HF cats.

Hey Blackout, how do you like the banks ram air?? did you notice any significant HP or mileage gains... I would like to know. Also did it make you exhaust loader and make a for a noisey intake. I am considering getting a new banks ram air as well, I cant decide what to get between the banks ram air or the S&B set up. I too have the Roush Off Road exhaust and I love It.
