I have the standard exhaust on my car until the centre muffler, from there
it is a 2 1/4" pip all the way to the back, with no muffler. If you like
your car to have a meaty sound, and sets of the odd car alarm whilst driving
through a carpark, then go with that option. Mine is welded to the end of
the centre muffler. If you go bigger than 2 1'4" you may have trouble
clearing the rear caliper, or find it runs extremely close and tranfers a
lot of heat to it.

Probably been hammered flat on speedhumps and bumps in the road. It doesn't
help the flow, but it doesn't hinder it to a noticeable extent. The only
option is a replacement set of extractors like Vin Sharp's ones. But they
are steel, so any hit on the pipes will more than likely break the studs in
the block. If you hit the iron ones, they break first, not the studs (dont
ask how I know - twice). Vin's extractors are claimed to increase horsepower
by around 6-8hp, but we couldn't notice a big difference.....
