Hey guys, i have a 08 Silverado and purchased a MBRP 4" Exhaust system for it. I had to sawzall my old exhaust out and when i started putting in the new exhaust i noticed a few bends in the stock exhaust that just are not there on my aftermarket exhaust. i figured maybe the mounting system was different and it would just work. I got the front pipe on (off the turbo) and immediately ran into issues when following the laughable instructions. the hanger clamp, when attached to the exhaust sits too high, even when the exhaust is as low as it can go. So i have the second part (labeled 37" extension pipe) connected to the front pipe, and it is sitting metal on metal right now. I can't figure out what i have done wrong, in the instructions it says i need to unbolt the rubber isolation hanger from the transmission then re-attach it. well, i used a sawzall so i never had to remove it and the instructions are so vague i don't know if it wanted me to attach the isolation mount differently.... anywho, i got a video showing my issue better than i can explain it. I will include a picture of the installation instructions.... what am i missing here?

For SURE, MBRP needs to do a much better job in getting their parts to fit our trucks. No excuse for the parts not fitting correctly.

If you still have regens, I'd be concerned about that spare. Those pipes can get very hot.When I deleted my truck, I put an extra clamp on the pipe and it held a self-made aluminum shield between the pipe and the spare tire. So far, no problems, but then I don't regen.
Thanks for the tip, but i have a EFiLive tune that has a DPF delete on it, should stop my truck from doing any regens.
