Default Flowmaster

I've always been a Flowmaster fan, I've used them in all my Mustangs, I'm currently running 40 Series DeltaIIs in the Roush and sound insane, and the 44 Series in the Excursion.... Now I wanna beef up the sound in my H2, what's the best Flowmaster choice for a 6.0 that gives it a mean throaty sound? Not too quiet, but not too loud?

Thanks for your comments in advance.

If your after Power than a Slowmaster is not the way to go ,if you want the Slowmaster sound you can get a Cherry bomb chambered muf that makes slightly more power with the same sound ( DRONE).

I'm open for any suggestions, what do you recommend? primarily I'm looking for sound, but more power would be nice too

Long tube headers ,high flow cats and a mandrel bent cat back system will give you power and sound . a cat back made to fit system will be and easy install and give you good clearence . check out Dynatech long tubes ,a lot of guys like Magnaflo . pick one you like the sound of and the long tubes will make it even better.

I'm a flowmaster fan and find the small diff. in power if measurable is not enough I worry about. My rig is built and being built for HP/spd. so I try to grab any HP I can get worth the money but, relieving to much back pressure can work against you. I run full stainless long tube dynatec catback sys. with flowmaster super 40's and sound great. Cruise is deep but, not bothersome. When I jump on supercharger there is no mistake you hear it. They came out with the 44's the next year and if I had not had my full sys. header to tailpipe Jet Hot coated in polished look I would have tried 44's.

CORSA SPORT with single tip! Great sound, a little power. easy install. off road tip available as well. no tips to come down on off road this way. They are about 1K though.
