To be perfectly truthful, even when it was first fitted i did not really notice a huge difference either in performance or exhaust note
, and cos i've had it on the car soooo long now, i'm not really sure what the original 'straight' system sounded like anyway
. Although she still pops and cracks like a good sud should
The only panels that have been replaced are the wings, and this is the second set on the car, the next worst bits are the rear arches, i'd love to get new ones welded on but i'm not in a position to be doing that right now. The rear panel did have a hole in it, but the rust was ground out and the damage made good.
The only points of concern now are the front and rear screen surrounds, where there is rust holes. I'm going to get the screens taken out to get a better look, but someone i know said it would be difficult to weld there without removing the dash (he said it would get very hot and be likely to catch fire!!)
The only other welding on the car is underneath where the big floor grommets have rusted away and plates have been welded over the holes.
