my friend told me he would give me his flomaster super 40 off of his gas gmc 2500 that is a 2001 i know nothing about that sort of thing but do you guys think it would fit a 2007 hummer h3? thanks for the help! he is giving me just the muffler

 

but one way to see is,go to the flowmaster site,pretend u r ordering it for his car,then pretend u r ordering it for your car.
if the part numbers are the same,,well it might fit

 

try this thread...

Flow master shared they need the inlet pipe measured and the off-set from the original muffler to match to a part number.
...have not been under the truck the new used H3 yet.... I plan to look in the mechanics cd I purchased to see if it is identified ..anyone know the answer to these questions..thanks

 

nothing has to be an exact fit as far as just a muffler goes. your muffler dude will just bend some pipe, expand it or whatever to make anything fit. just go to a muffler shop and tell them what you want.

 

Makes sense...thanks...

 

I am wanting to do something to my exhaust as well. Since I live in CA for now I have to have a cat. I know some people have said they just removed the muffler and put in a straight pipe. I looked under mine the other day to see what was there. I need a little clarification of what is what under there. It appears that the cat is right there by the transfer case. There is another similar bulge in the pipe near the rear axle. And then at the rear is what I assumed was the muffler. Is this correct? What is the bulge near the rear axle? What can I remove? Thanks guys.

 

I have a brand new GM performance parts exhaust system for sale .

 

its the resonator, look at the thread i posted above.

 

Sounds good with the V8, Darren. I would if it would sounds as good with the I-5. Nothing worse than sounding like a ricer with a fart can. I was considering putting a Camaro style duel outlet muffler on too.
