Glad you kept it! I've been checking out your build. Love the airbox :)

Thank you! I worked hard on this. I’m glad you like it. Hopefully it will be ready to tune by the end of April

I shortened the downpipe a little to fit this
I hope haha. Wish me luck. 3” oval tubing. More ground clearance and will leave more room from melting the axle boot

Here’s progress so far. No oval tubing. Can’t get it to fit 😞 do you all run 3” tubing? I’m worried about ground clearance and melting things?

I’ve got 3/4” clearance from the drive axle boot. Heat wrap and a custom heat shield

Let’s see if 16ga 304ss amazon stuff holds up for the flex pipe back

Got the downpipes all welded up. Had to take a little off the subframe pinch weld. Doing the heat shields and secondary support bracket now

1.9 bar / 13.5 psi or 2.2 bar / 17.5 psi?
That is the question
If I was to guess the intake hose at the throttle body popping off is its weakest link.
Bonding silicone to aluminum:
Permabond
Polyolefin primer
Permabond cyanoacrylate 105

:bangshead: there’s only 3 cat back exhaust mounting points
I’m gonna have to fix that. There’s not much room with a 3” pipe in a 2” ditch. I’m debating about just bolting the flex pipe back straight to the car with rubber isolators

I bypassed going up and around the diff on mine. It is now the first thing that hits anything. I plan on redoing mine to snake around. Your image looks like what I had I mind. 45deg over the CV. I kinda gave up fitting it correctly. Even the same box of amazon pipe but in 2.5 :D Hanger situation sucks. My rear oem muffler broke at the welds, so it was my quick fix. :bangshead:

:hide: I am not happy with my setup.

Yes. A 3” 45 degree slightly cocked will go right through with 2 bolts flanges on both ends to get it out without lowering the subframe or axle. There’s only 1/4” of clearance in a bunch of spots going through though. I’m currently figuring out the mounting situation

There’s room for a muffler under the passenger side rear seat
I’m debating about making one with a little copper and/or other crazy metals to get a different exhaust tone. Already going to have a Flowmaster under the trunk
