    Exactly! And removing the heatshield etc just seems like so much work. Even though, it really is not much work at all

    Has there been an issue clearing this bar? Should I just remove the bar? The exhaust does rattle on it... IMG_2969.jpg

    I think that you can reach the header bolts from under the car... at least 3 of them..

    I had to take it off to get the stock exhaust off.. Not sure if it has any purpose.

    Yes, I actually removed that bar. Because of the rattling, it was really bad haha

    I assume it is part of the suspension tweaks to try and tighten up the body roll.

    if you want to retain that little piece of steel, just install 2 washers under it and reinstall. I have not found it makes any noticeable difference when kept in place or removed for any of the cars we've had in here, but spacing it down slightly allows the larger exhaust to fit just fine. hope this helps

    If you have the invidia N1 paired with this downpipe, the hangers near the exhaust tip will rattle up against the sheet of metal hanging down right behind it. I am trying to figure out what to do with mine now, I may just attempt to put some sort of rubber there to keep it from being noisy. Again, its only sometimes and not all the time. Just figured I would let anyone know with the same setup as me.

    Just bought the other piece of my exhaust! :) Got my FR catback from @axionindustries. I can't wait for it to get here. Thanks to @squiggy for this awesome DIY! Hopefully all goes smoothly. Pairing it up to my FR catted DP.

    If you have removed the bolts, you just need to wiggle them a little bit or maybe pull the arm off the windshield first as if you are cleaning the windshield. They will come off. Even I was surprised at how they felt the first time I tried to take them off

    Not sure what you guys are talking about. Just flip the wipers up and wiggle. If you manage to break your windshield, you have done something severely wrong and shouldn't be attempting to even fill a gas tank.

    Quit trying to scare people.

    The wipers were kind of tricky for me but then all of the sudden they just came loose without me even doing anything it seemed. Just light pressure it all it takes and then poof they come off!
