For all the people that say an h-pipe shows no gains, that is completely false. I raced my friends bmw Z4 when I was stock and took it all the way up to the top of third gear. When I got the big 20 inch rims on there, we raced again. This time he started gaining th elead early into second. After I got my dual american thunder mufflers put on with the h-pipe, we raced again. This I performed the same accomplishment as I did stock. Hmmm I wonder if I take off those rims how quick it will be?
Anyway, go with the h. Its an amazing sound. Personally, if you are looking for the rumble, go with the Flowmaster American Thunders. If you would like to see the first video I ever took let me know.
