DIY: Modify Skunk2 exhaust hangers

[dentrecords]

I found that the Skunk2 exhaust hangers above the muffler were too long and were rattling against the body of the car, being both annoying, and eventually leading to an exposed piece of metal to rust up on me.

What you'll need:

Jack, Ratcheting Jack Stands, Chocks (all the standard stuff, you should know the deal with this before attempting anything below)

14mm wrench, 14mm ratchet, Angle Grinder, a towel to rest the muffler on. Oh, and safety glasses.

1. Jack the car up using all the appropriate precautions
2. Take the muffler off
3. Set it down on a towel, make sure that the towel is only directly underneath the exhaust and there is no extra bit sticking out from underneath - sparks are going to fly like crazy here. (note - put your safety glasses on)
4. Measure about 1" from the end of the hangers and mark them.
5. Take a deep breath then start the angle grinder... with great care, slowly ease it onto the spot you've just marked on the hanger and begin to put pressure down onto the hanger. You'll start to carve out a notch, and you're just going to cut through the entire width of the hanger. As you get close to cutting through, apply minimal pressure, and take care not to touch any portion of the muffler with the grinding disc. Take a few extra moments and you'll get that last portion off. Use the grinder to smooth the edges a bit. Enjoy the orange glow from the near molten metal that is the exhaust hanger.

Note: The hanger and the bit you just cut off are extremely hot at this point - do not even think about touching these for at least 10-15 minutes afterwards.

6. Reinstall the muffler, inspect for clearance.

Here are some pics.

I'm definitely going to make Skunk2 aware of this so they can shorten the length of the exhaust hangers a bit (ticket #2540). This would be something I'd recommend people just getting this exhaust do before installing it on their Si for the first time.

Not in that picture.

The roads were terrible that day. There wouldn't have been any point to it.

They work - perhaps they are getting blocked on your end.

yeah i thought i was the only one that ran into that problem on the install. i just cut the piece of metal on the bumper which was real thin.

Figured this out on my own, but good writeup. I hope they fix this for future people. It's kind of a hassle having to knock out studs on the cat and modify these hangars. Alot of people don't wanna have to mess with that much stuff when they pay as much as they have to for this exhaust.

The BC has movable rear hangers because they attach to the muffler separately. I have had no rattle issues at all.

They haven't done anything about it so far? Strange, I opened an issue with them..

[NighHawk8Gen]

mine does it too....i will be fixing that thanks to the OP!

I cut them using a sawz-all

Well, UPS informs me that my skunk II is sitting on my door step right now yeehawww. I'll look and see if my hangers are any different than yours in length. Hard to tell the diameter of them in the pics, but do you think I could just cut them off with some bolt cutters? I have some monster ones that are about 4 feet long.

Just installed mine today. I had to cut the hanger as well. The exhaust turned out to be too loud for me though and I'm going to have to find some solution other than the silencer.
