Catted H question...?

[tucker-tx]

Can anyone tell me what kind of sound difference to expect with a high flow catted H pipe on my o4 GT? I know a lot depends on cat back selection and so forth, I've got flowmaster single chambers on right now and they sound pretty aggresive as is. Will the H give me an even more aggresive sound? Any info would be very helpful.

I've got the catted MRT H-pipe with the stock catback. The catted H made the exhaust tone deeper and a little louder but not a lot louder. It'll probably have a bigger impact on your setup since you have flows.
