Show me your SpecE46 Exhuast

As noted, the FB page is a lousy for searching build topics. I thought I would start a post with "SpecE46 Exhaust" in the title since it is easily searchable. I've been wrestling with the exhaust for two days and am hoping this thread could help me and others with:
  1. Installation tips
  2. Pictures
  3. Notes
  4. Comments

Thanks!

I haven't done mine yet, it's sitting in the boxes still but curious what you're having issues with?

Getting all the pieces to rotate into place just right was a bit of a pain. I recommend putting it up on the car with everything very loose so they can all rotate around. It'll fit VERY tight against the car at the Y-pipe and rear sway mount.

Evan is correct, it's tight but fits well when you get it positioned correctly. Start be attaching to the headers and work back. Get everything assembled loose and then rotate into position and tighten. Don't over tighten the stainless clamps or you will break the studs off when you try to loosen them later.

That seems to be the trick Evan and John. It seems the only pieces that can be rotated that makes a difference is the rear section and muffler itself. As such, mine hangs down about an inch lower than stock at the midsection support brace. If I force the midsection up to where I can mount the support, the flange between the midsection and rear sections are up in the heat shields, the rear section hits the sway bar mount, and the muffler is cockeyed and would only mount on one of the hangers.

I know installation/fitment will vary slightly from car to car. My intention with this thread is to gather some information on individual builder's experience to help the community.

if you have hotchkis sway bars you'll probably need to grind the corner of one of the brackets. have an angle grinder ready!

Can someone post some pictures of the mounting points? Do you reuse the stock hardware? What do I do with all the hardware in the bag that came with the race exhaust system?

The v-band clamps should be self-explanatory. Here are a few pictures of how I hung the muffler and supported the mid-section.

These first two show the muffler hangers, first the left side, and then the right. The stock rubber mountings were retained on both sides.

The exhuast is down at the moment but this last picture shows the cross member support. I only retained the rear most support. I had to use 1/2" spacers between the cross-member and the chassis mounting points. New bolts were sourced from ACE for that.

Hope this helps!
