Recently I installed a 2.5" dynomax cat back and because I have a GlobalWest Traklink torque arm, there's an aluminum plate that gets in the way of the flowtubes leading to the mufflers. I went to a meineke for help installing the catback system and they had to custom bend a new flow tube to go from the h-pipe to the muffler on the driver's side. They used a 2 1/4" pipe and they crimped it like crazy!! They said they had no way to bend a 2 1/2" pipe and they couldn't do mandrel bends either in the shop.. so now there's a bottle neck about 1.5" instead of nice flowing 2.5" on one side. Is this going to hurt performance? Should I go somewhere else to get it fixed right or is it not worth it??
