Installation Time: Afternoon
July 24, 2019
The exhaust itself sounds pretty good! Not like an annoying kazoo. Gives the engine a nice rumble. Just installed this over the weekend and since my car is now coming up on 14 years old I'll give some quick tips on removing the old one and installing the new one:
Unbolt all hangers (these gave me no problem)
Buy PB Blaster! My muffler was so rusted on that I thought it was welded at one point. I live in the northeast where the winters are not kind to cars. This stuff made quick work of the caked on rust
Definitely use an impact wrench to get the 15mm bolt off the exhaust clamp, other wise go Hulk mode on it with your socket wrench
Even when you remove the bolt, the clamp can/will be rusted on so bad that it'll behave like you didn't remove the bolt at all. Drench it in more PB Blaster!
Keep letting it soak. Let your frustration out on it with a rubber mallet. Use a flathead screwdriver and wedge it into the C clamp to begin prying it off. Use the mallet to wedge it in there good.
Eventually the clamp will let go. This is when you can start wrestling it off. If you feel a gritty sound when you twist at it, that means it's working. Spray more pb in there, wait a couple minutes, and wrestle with it again.
The bolt on the new clamp that comes with the boom tube is 11mm. Use this size specifically and make sure it's a DEEP SOCKET 11mm. It's impossible to tighten the new clamp on all the way without the deep socket. A regular socket will only get you about 3/4 of the way.
Fitment: I tried my best to shove the pipe into the boom tube as far as it went, and even then the tip still made light contact with the bumper. It's easy to shave down but if it's contacting at all I promise you it will begin to melt your bumper.
Definitely took much longer than one hour to complete. I'd say a whole afternoon to a day if you're well prepared with everything on hand. One hour would apply to a rust free, garaged mustang like the one in the video.
