Does anybody notice a power increase with the Gibson exhaust?

Mike..There is a conservitive increase IMO..Feels more peppy compared to the factory exhaust..Not much, but a mild noticable increase in responsiveness...A combination of a K&N Intake and the exhaust complimented each other IMO.

Would you think there is any difference performance-wise between the Gibson, Borla and MagnaFlow exhaust systems? I would think they are probably all the same as far as any boost in HP, but the sounds are what would be the big difference.

I would say like you say..No difference, just the exhaust note may vary a little between them.

THANK YOU ONCE AGAIN. YOU ARE MY EXHAUST SYSTEM GOD!

Seriously though, I'm going to do this once and once only, so I want to do it right. I guess for the money, you can't go wrong with the Gibson.

My pleasure Mike..

If you do go with a Gibson, hook up with this guy here in OKC....

Finished installing the Gibson Cat-back Split tail exhaust P/N #312700 from 4wheel Parts of Oklahoma..(405) 946-3509 on the WIFE'S H3.....SWEET!!!!!!!
EASY install (2 of my students and me spent about 1 1/2 hour--removing the old system in ONE PIECE and installing the new system)----only thing I did was spray the pipes and muffler with some 2000 degree silver paint, not a bright silver (same paint use on my vette's exhaust wrap from Eastwood Co.)
Cost was $383.00(at the 1st of this year it was $333.00 but that's LIFE) --PLUS sales tax and shipping. Shipping was SUPER QUICK.
If you call 4wheel Parts of Oklahoma ASK for Mark---GREAT Guy to deal with. TELL him you are a member of Hummer Forum and he will "help-out on the Shipping".
THE SOUND!!!!! My wife said "If it loud on the inside....you will be TAKING it OFF". After driving for a week and taking a 400 mile get-a-way trip. SHE LOVE the SOUND!!!!! and the S.S pipes under the rear bumper.
Dennis THANKS for the ADVICE on this system!!!! YOU were right on target-----GREAT EXHAUST SYSTEM!!!!

I actually read this part, all on my own too! If I do this, it won't be for a couple of months. We'll see what the prices are then.

I used the Magnaflow. I just love the tone. I went one step further. I had my exhaust guy take the stock mandrel bent exhaust and cut it apart and use it to get rid of the crushed pipes in the down pipe. Before and after the cat the exhaust is seriously crushed and the piping is real restrictive.

Did you notice a change in sound or performance from removing the crushed pipes?

I noticed a big difference, but I also did the Volant intake and Ariaid TB spacer all at the same time. My wife drove the truck home from the exhaust shop w/o the TB spacer and intake, so I'm not sure about just the exhaust. I drove it after installing the intake and spacer. I think it was worth the extra $$ for the whole setup. Just need an agressive tune and speedo correct for the new tires and I'll be all set!!

Interesting! Thanks for the reply!

Dennis... I'm thinking of buying the same Exhaust Sys for my Rig as you have, and my question is... if i was to remove the tips before going off-roading, would the exhaust pipes clear the bumper enough so they won't get crushed?

Yes, I believe you would have the clearence as long as you don't reverse into a hill..take a look here..see if this helps
 

Oh Ya.... Appears to have LOTS of clearence....Thanks Dennis!!!
Man that is one CLEAN underside... do you even drive it??? Or is this Pic soon after you purshased your Truck, you had the Exhaust Installed??? No Soot in the Tips!!!

Ditto!  NO DIRT!

Thanks for everyone's input. I recently purchased and installed the Gibson split rear exhaust kit. I am still getting used to the throaty sound form the I5!

I haven't noticed much power gain. I am going to wait a few weeks before I test the gas mileage since I am driving it by sound right now (now I understand why Harley Davidson riders gun their bikes all the time).

For those that still want to know what it sounds like, here is a video clip - LINKY I also have a few pics here: LINKY

Hi,

I'm new in here and wanna buy an exhaust with four tips.

What do you advice me?

Greetings
 
Get any brand to your liking of the dual exhaust Cat-back exhaust systems (search this topic section)
 
 
and add a set of something like these..  Dual Tips

I put the Billy Boat Dual Cat-back exhaust system in my 2006 H3 and it sounds great.  I believe the Billy Boat web site has sound tracks www.bbexhaust.com.  The exhaust not only sounds tough but looks great.  Excellent chrome job.  I think the exhaust was about $700.
 
At the same time I did the exhaust I installed the K&N Chrome air intake system and PowerAid throttle body spacer.
 
I purchased all three from Stallion Customs and negotiated a price of 999.99.
 
I have not tested the truck on a dynometer or whatever you call those things but I will tell you there was a noticeble and significant change in performance.  Both from a stop and on the road in a climbing or passing mode.

Thanks a lot for your help Dennis.

In addition to the dual tips you showed me, I wanna have a similar sound to that exhaust in the link. I wanna hear my Hummer roaring. What do you advice me?

Actually Khalil, I think they all sound pretty darn good..But I'm partcial to the GIBSON brand Cat-back system..It's a matter of how much you wanna spend..

Thanks Dennis.

I guess i'll install a Gibson cat back.
