This past Saturday, I went to a local highly-recommended exhaust shop and had a dual exhaust installed on my Suburban. I had a laundry list of requirements that needed to be met such as having the exhaust run on 1 side of the truck for a future on-board air system, no exhaust tips, quiet on the highway with no drone, and not lose low end by going with too large an exhaust. Well, he more or less met the requirements. He installed dual turbo mufflers for a quiet drive, and they are. They just don't have any rumble to them... The exhaust is new from right after the donut gasket flange all the way back. I thought I was getting some catalytic converters, but no, none to be found. He did install an X-pipe where the cat used to be. All the exhaust runs from the front to back on the drivers side, then right before the axle are the pair of turbo mufflers on edge. Then it cuts over to each side with a side exit right behind the wheel. I wanted a nearly straight output like the factory exhaust, but he put it at more of a 45 degree angle. I'm not crazy about it, but I'll get over it I guess. Then he didn't clean up the ends of the pipe where they exit, and I think they're not even. A round file will clean up the ends, but not being even can't be easily fixed without cutting out part of the pipe and remaking it. I might take it back to the shop next weekend and have them fix up the rear exhaust exits. Maybe even make them remake them for the flat angle I wanted in the first place. I paid $400 for the system. How'd I do? Pics and video to follow.
