some chops i did for potential products:

Undedecided if i want it to go under exhaust tip or not. i like both a lot. actual exhaust tip will not be that large. it'll be only slightly larger than the pipes (3"). I've decided not to do stock shaped tips. the tips may also be dual-tips. however, our single exhaust version will only be single tip. product to be made in CF. will also be a true diffuser. of course design will slightly redesigned so that both dual exhaust and single exhaust will look ok without being out of place.
middle mesh (in front of intercooler) will be included with the side vents because stock one will not work with these vents.

front vents will be CF.
optional splitter (true splitter, not just for styling) will complete the overall look
