(Do not have much mechanical knowledge, so the shops love me when I come pulling in). I just bought a 2015 Chevy 2500HD LML. I had a 2008 GMC 2500HD LMM which had a H&S Mini Max. I would like to get another H&S Mini Max but was told that they are pretty much out of business/out of the game. At least that's what I was told. Is this true? The person that told me this was telling me to go with EFI Live instead. Should I?

I was also thinking about upgrading the exhaust as well. When I bought my 2008 GMC it already had the tuner and upgrades to it. It had a 5" MBRP exhaust system. So should I go the same route with my 2015 and get a 5" exhaust system along with the tuner? I'm really looking for more power and better MPG's.

I had a 2013 lml for a couple of years. I ran a efi live autocal with a street tune and a tow tune along with a 5" flo pro exhaust. It was loud when i got on it. 4" would be plenty. I just had the emissions tuned out and was on my way to having the full delete done but i got rid of it before i got to that point. I sometimes wish i would've kept the truck because it was so fun to drive and it would pull a mountain!! Post a pic up of yours.
