These are awesome mufflers, that sound great, and are supper easy to install. I gave a 4 for appearance because the only way they could be better is if they were polished. I also gave a 4 on price, because let's face it. Who wouldn't want to pay less? Theses really are FLIP'N good cat back system.
3 inch test pipes on Dodge challenger
I purchased these for a 6.4L to replace the mid pipes. When initially received I immediately saw the great quality. They are made of really good stainless steel, bongs are nicely welded, nice bends on for being 3 inch pipe. The only thing is that these fell short and once they were bolted to the stock srt shorty header/manifold. They were about 1.5-2 inches too short. Not sure why, if because my stock catback had been modified by removing the resonators. It all fit before i took to muffler shop
