Taken after riding the trails at AM Generals' off road course. NOTE: I purchased new roof rails the day prior. SMA exhuast is next. Will post pics soon.

I just had Bergstrom Hummer install a SMA Dual exhaust on my H3. And here are my thoughts. The exhaust note is much louder when accelerating from 0 to 50. Once on the highway the exhaust produces a louder than normal mellow drone. I have to turn up the radio a bit louder now to overcome the exhaust noise when driving. I didn't get a chance to guage the MPG yet. I will soon. I have the K&N CAI installed as well, so with the combination of the two I hope to see a slight change in better gas mileage. As for performace I do notice acceleration is more responsive. But without the stock air intake resenator and the stock muffler with its baffles and resenator to keep the loud noise at bay, I sound like a old 77' Datson B210 with a bad exhaust leak doing a 1/4 mile at Pomona dragway, thats if I really step on it. Also what I noticed is when I take my foot off the accelerator and let the H3 cruise, the SMA exhaust note changes as the gearing changes, as if the downshifting note goes from low sound to a lower muffled roar. I do like that sound. It's normally as I exit of the Interstate and ease off the gas pedal I will get that transition in the exhaust sound.
Overall I do like the look it gives from the rear, with the chrome tips. I would give it a 9 out of 10. As for the sound, (given the the fact that I know its only a 5 cyl powerplant.) I give the sound a 4 out of 10. As for gas performace with the CAI and the exhaust, I will have to let you all know later. Here are the pics.

Another closer shot of the dual exhaust.

OH YEAH I FORGOT. I HAD MUD FLAPS INSTALLED TOO.

Heres a shot of the HUMMER H3 mountain bike. I purchased this at the 2005 AirVenture in Oshkosh. Matching color, Victory Red.

I bet it would cost at least 600.00 to have my exhaust replaced there. Oh well, I love the parts department.

Flyingbadger,

Where did you get your front grill with the word HUMMER on it?

Guppy, go to the H3 forum on Customizing and Mods. Look for the New H3 Grille Post by Flyingbadger.

Yech, Datsun B210 sound effects. Isn't that a a bit of money for that type of sound? Are you sure a lot of that bad sound isn't coming from the K&N intake/inhaler?

Consider trying stock intake again and letting us know how it sounds then.

Steve

Its worth a try.

Heres my new radio that got installed on December 15th 2005. KENWOOD EXCELON 25th ANV. DVD PLAYER (XXV-05V} XM, NAV, rear camera, and Video IPOD compatable. Also installed is the ALPINE center channel speaker. Cost for everything including install was around $2200.00 See my post on the Technical and Mod forum to see more pics.

Does the system integrate well with the phone and onstar????

I am using a Onstar modulator from soundgate.
http://www.soundgate.com This allows for me to still use Onstar. It cost around $130.00 and they ship free using Fedex 3 day service.

great info badger, let us know about the sound with the stock filter if you try it.

Thanks for the info!

Nice grill. Everybody to Badger's . . . brats all around.

Badger: when you did the install on your Kenwood, which looks totally schweeeeet, I might add, what were you told (if anything) regarding your warranty being voided? The dealer I ordered my truck from sez any aftermarket audio components installed void the warranty.

I hope they did'nt mean the whole warranty of the vehicle? That would be a lil over the top.
I could understand if they meant electrical problems were to occur after a aftermarket install of a audio component the dealer would not honor the warranty. But the fact is that most people will always do some kind of radio upgrade on their new cars. I never had the dealer come right out and tell me that they would'nt honor any type of warranty since I put the Kenwood in. Owners manual probably has a statement regarding aftermarket items being installed and the warranty issue that apply.
