Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Looking for that deep rumble sound on my H2, what mufflers do yall have?

More then likely thats the sound you are referencing, I have had many Borla mufflers & systems I don't like how raspy they are without cats & magnflo's just sound like a louder version of a $19 turbo muffler.

I would follow my own advise on my Deuce but I don't want to get the attention of every walker around as I creep thru the woods

I'm not so sure I would compare a Magnaflow to a cheap Turbo muffler. A set of series 40's w/o cats will sound badass though...

Flowmaster cat back on mine. Street/pavement-wise, it sounds good n evil when leavin a stoplight. Can't hear it over the mud grapplers after about 25-30mph... Lol I enjoy the v8 note while wheelin myself. Only time she gets obnoxiously loud is when ya hammer down to get thru or over somethin, which I feel it's supposed to! Isn't that why they call it the "loud pedal"??! Got a helluva deal at autoanything too. Was the first thing I'd bought from them so there was a 15% discount, and at the time there was a $75 rebate runnin. Came out just over 3 bills!

ak47dennis is right, no cats and two 40's Flowmasters will be probably what you want. That's the setup on mine and everyone ive ran into loves it. Even if you want to keep the cats its still sounds very good. I've had Magnaflow on previous rides and I've heard them on H2's and IMO they are way to quiet.

1. Use google
2. One per 02
3. Not aware of any "power programmers" that will delete 02's. IMO they are a waste of money, i have always spent the $$ to have ECM's tuned right. It's been a little bit since I have had one done don't know who to recommended anymore.
