Background: I am using the FFR-supplied twin side pipes
I am wondering what kind of bushings you may be using for hanging your side pipes via the 2-bolt tab on the frame and the 1-bolt tab on the side pipes. The kit setup uses an L-bracket and two rubber bushings with a pair of studs each at the frame -to- L-bracket union. IMO, this is a little soft. I am thinking the individual round rubber bushings could be replaced with a single poly bushing with two holes on the correct center, which would be stiffer, and keep the side pipes better aligned in their recess below the doors (as opposed to sagging ...) Stiffer also means a little less stress on the ball header union, which is ALWAYS stretching and loosening. I have to check that connection more than I check my oil :-)
There are a lot of exhaust hangers out there which are a high-density poly design, of the correct thickness, but the centers &/or hole diameters are off. And yes, I can stack some stiffer but somewhat compliant washers in place of the soft rubber grommets, but was thinking maybe others have solved this nit already :-)
This is the maintenance stuff I seem to be mostly focusing on after getting some road miles on the Coupe. Chasing down those rattles :-)
Off this week to apply UV/IR film on the hatch glass and a visor brow on the windshield. Note that the glass that comes with the coupe does not have what is now standard film application. Of course, it is easier to do this upgrade BEFORE installing hatch and windshield .... Oops ... :-)
