Did some final grinding on the exhaust pipe to smooth and round the edges where needed and remove any burrs from the cutting process. The two brackets that hold the Sling exhaust pipe on are different sizes with the small one going onto the remaining stock exhaust section. I found it easier to put the bracket on the stock exhaust first and then push the Sling exhaust on so that the thickness of both items didn't have to push through the available gap with the support flange. Once on then added second bracket and snug tightened both brackets for now. Once the cowling and exhaust fiberglass are fitted I may need to change the angle of the Sling exhaust slightly so will fully tighten down then.
Added the intercooler support brackets.
Test fit the wheel pants and began reviewing where the holes need to be drilled.
