I assume the insulation from the factory is still part of the undercar exhaust choice .
The street cars can also be ordered thru SPF dealers without hood scoops or without roll bars if ya want an ALL original street version car look ....also , the hood if scoop is on it may not have the rivets with the scoop blended into the hood at its edges vs looking 'stuck on' with rivets like the S/C car versions . Scoops can be ordered either way .
It looks good, sounds good , is well insulated by the factory underneath. If that is what ya want , go4it . Bill

Bill, that is the set up all AutoKraft AC's MKIV's (non lightweights) came with from factory, except silencers/mufflers were in rear wheel wells. Rear tread is about 4inches wider than a MKIII via Frua uprights, bearings and compomotives 15's or 16's with a bit moire backspace. They did this as the cars were equipped with cats and passed epa regs. Jim
