THX Jeff Lilly exh fab.

I got this idea from Jeff Lilly and got the JL link from a forum member. THX

Pretty happy with how this custom bracket/hanger turned out.





There's even some of my crappy welding in there.

what exactly are you referring to here?
please tell me that you are not going to leave the threaded part of those clamps hanging down to snag on things

I found 2 unused threaded holes and fabricated an extra exhaust hanger.
And no the car is many months from being driven.

Looks good!

Is that the manifold/header flange next to the hanger? Normally I just put a single hanger in the middle of the pipe(s), leaving the header-pipe joint unsupported so its fairly flexible to make lining everything up easier. If you run into any issues with cracking/leaking, you might try making the system a bit more flexible. Rigidity is the enemy of exhausts IME, especially up front on turbo vehicles as EVERYTHING needs to move indepently.

This is all learn as you go for me. Your input is welcome.

The factory bracket was removed but it was about where I put the new hanger. There are two flex joints in there.

Part of what was driving me in this redo was the crappy work that was done on the exhaust system by (poorly chosen by me) mod/tuner shops. This is probably a little over kill but previously the Exh. stm was supported at the turbo down pipe and at the rear...that was it.

I'm curious as to what benefit this provides? Not being negative because it looks nice but just not sure why you did this.

Ok, wasnt criticizing just curious. If the factory had one there then youre probably fine, and no need to redesign the wheel. Some folks seriously overdo things and mount things solid that need to flex, make extra work for themselves, or make things a PITA to assemble....glad youre not one in this case.

You learn a lot by doing, keep at it and keep us posted.

1.) This is an aftermarket product (HKS) that was originally installed poorly and to a certain extent incorrectly. The hangers were mis-aligned and some attach points were not used. It leaked and IMO it and the turbo and engine mounts were under undo stress. Additionally, even this very expensive product was flawed...well designed but poorly excicuted.

2.) The CATS were removed from the car (without even asking me) and I need to pass emmissions. After market CATS back in.

3.) I needed to add a WB o2 bung.

4.) This particular bracket in the OEM version had very little flex. I tried to design it to have lots of twist and flex.

It was actually [for me] very challenging to design with out any mockups or for that matter experience. Lots of joints and angles, twists and turn. But this is what my mine seems to crave and I really enjoyed the process.

part of rear hanger fix...had to extend hanger rod-
