just finished up with the o/r h-pipe flowmaster classics, jlt cai and brenspeed tune. Sounds better than stock but the flowmasters put out a rasp or trumpet or reverberation when you rev it out, its starting to bug me, anybody else with these mufflers have it?

i hate that as well, i am ordering exhaust this week. teh best sounding set up i have heard is the roush extreme on the 2010 cars.

Is there anyway you can make an exhaust clip? Ive been dying to hear these mufflers with the o/r h?

Yeah I'm swapping out the Flows for some Macs. Thought I was picking up today but ran into some problems so the car is still in the shop!

The flowmaster classics sound different from the regular 40 series.

But I love my macs with the o/r H, sound like a f*cking beast. I get a ton of compliments with them.

Mine don't do that at all with the shock H and cats.

It happens with the o/r h

I have flowmasters and the h pipe and im not liking the trumpeting so im gonna put some hi flows on and hopefully that will alieviate the trumpeting a bit

I want that sound but would like to keep the cats, would high-flow cats and h-pipe still sound like that?
