Hi, I’ve got a 2006 and am trying to get a new muffler put on. I just can’t figure out what the pipe sizes are. I think it’s 2.5 dual in and 2.5 dual out. I just need a 100% answer and would be great full if anyone could help.

 

It's 2.5 in and 3 or 3.5 out. They changed outlet size for 07 model year.

That’s a dual in and out right, I just want to make sure my exhaust isn’t different from what you’re describing.

 

If it's oem should be 2.50"x2.75". It's best to measure. oem part number: 10398386

 

Sorry the post below me is probably correct. I have replaced mine and in only has 1 outlet.

Amy recommendations on after market muffler for a 2006 H2? Mine appears to have a rattle inside...Muffler has 2 in & 2 out.. Trying to find a suitable replacement since the OEM is around $1000? lol

 

I purchased a Gibson cat back and love it! I got mine from Amazon for a little over $400. Part #312500

any video so we can hear the sound?

 

Walker SS(1/2 the price of gibson aluminized)..---> RockAuto

 

I'll work on a video. The Walker muffler is cheaper but what I purchased was an entire cat back system. No way I would have been able to just replace the muffler alone. That being said, the cat back system was a complete pain in the azz to install. If I had to do it all over again, I would have just taken it to a shop and paid someone to do it and I'm completely capable of all of this. 15 year old pipes don't like to give and flex anymore.
