We got the catback system from Magnaflow installed last weekend. We filmed a lot of video ("we" being my son and I) for his friend who does some youtube stuff. I'll post a link when the edits are done.
Overall, extremely happy with the results. It's a hair louder, but more than anything it's lower pitched with more "growl". There's also some of what I call "burble" on deceleration. Not the obnoxious backfire/cackle like a "burble tune", but just a much, much softer version of that I guess. We called that a burble back in the day, but the term seems to have morphed a bit.
Installation went well. Removing the original exhaust was all smooth except for getting the exhaust hangers off. We bent the tool trying to get them off and had to go to the auto parts store for a new one. We then used some silicone spray to lube it up a bit and finally got them off. Everything else went like clockwork. We followed the instructions and installed everything without tightening the bolts, then tweaked the alignment. It pretty much fell right into place. The tips were centered perfectly in the opening. Then we went back and started torquing to spec from front to rear. All stayed in place and we were done.
Also, the polished tips look amazing. They're slightly larger than stock and really gleam.
All in all, well worth the $$.....just need to figure out what to do with the old exhaust. I hate to toss it....only had 7k miles on it and looks practically new.
