I've searched the forums but there isent any info on the H2 side of things.

I'm not sure if I should go with the 10 series or the 40 series. I know most of you are happy with your 40's but has anyone tried the 10? Do you guys think it will be to loud?

Thanks.

 

If you still have cats, I think the series 10 will be OK(not obnoxious). Without cats, it's gonna be loud...about a step down from an open exhaust.

 

Ya I plan on keeping the cats in. I just don't wanna be that a**hole with the crazy annoying Hummer. Lol

 

Nate2106,

Here's a website....www.kinneysmufflershop.com.. there are a couple of Hummers with flowmasters, I think they are 40 series
