I have a couple of issues with the OR/H, one is I assume you smell gas, often. Second is here in Missouri I would have to swap it out every 2 years for inspection, kind of a pita if you ask me.

issue with smelling gas..... big deal its ok how did everyone with the old mustangs that did it......
and 2 we have same thing and i think in 2 years you'll have enough time to switch it out......
but hey thats just my opinion.... maybe i was too harsh man...... im just sayin if you were to spend alot of money for hi flow cats and putting it on and all that just cut the middle man out and take them off just seems easier

With no cats they are very loud, lol. I put the stock mufflers back on with an O/R-H and I think its perfect. After welding 4" tips on the stock mufflers of course.

I have the Flows with a Bassani X w/hi-flows and I love the sound. I get lots of compliments on it. Not overly loud but def louder than stock.

Sorry, no clip yet. There is a youtube clip with the same set up though. Just do a search for it and you should find it.

Here you go. Wasn't sure how to do the link thing, so you will have to cut and paste.
