Well I installed the mac h-pipe with little fuss! I like this new 3 piece unit=easier to install and no exhaust leaks! Used the hardware supplies. Sprayed every bolt with wd-40 and let it sit for atleast 30 minutes.I cut the smog pump pipe that connects to the factory h pipe with a die grinder and used a high temp blue silicone hose from a 6.0 powerstroke egr cooler. The hose fit perfectly i just removed the clamps and fittings from it and added two worm style clamps! Everything lined up smoothly. Off road H+flowmaster american thunder catback=
