Not Ranked
Back when I had EM build new exhaust system including headers I ordered the "low-back " mufflers option. When I received the new exhaust system, the mufflers were there normal mufflers with two parallel perforated pipes inside each muffler. Still all metal but not the low backs I had ordered and paid for.. The collectors and mufflers were short. I bought a 10 foot length of 3 1/2" exhaust pipe and cut pieces to add inches to the collectors and the mufflers. The mufflers were straight mufflers with rounded ends smaller inlet ant outlet tubes. I cut the mufflers and added length to everything. I incorporated a Car Chemistry disc units into the collectors, because I intended on getting everything ceramic coated. I even welded in bungs for oxygen sensors in the advent that I needed to later. If later a local cop decided that my exhaust was too noisy I had to have some where i could go and try to quiet it down . Ceramic coating is great for heat but any welding after is like welding dirt, I can work with the Car Chemistry unit to show i made an effort to quiet things down. I used Burns SS V clamp ends to use as a connection system. they even now have male & female versions of the flanges. one of each and a V clamp form a unit I have short headers that connect to the collector inside the body and then turn to form the collectors., then collector to muffler, muffler to turn out tip. All short lengths that all got ceramic coated inside and out. A friend that can TIG weld all the stuff together. I ended up with two different sets of mufflers and a set of straight pipes that look like the mufflers. the V clamps are not noticeable, and can all be removed or changed with a 7/16th wrench. The sticker is twenty years ago the SS V clamp and two flange units were $75 each I think I bought 8 total. I have used the low back from day one and no tickets yet.
