I've got a custom made job, came with the car from japan and was a pleasant surprise, full stainless system, manifold, dumps, 3" to 3.5" fronts, 4" system, no cat initially but now has a 4" Magic One which caused no real difference to power delivery. Exhaust is fairly quiet for its size, just a nice deep note.
I agree with Iwells in that you should get the Trust/Greddy Split dump/fronts, Magic cat and then some decent cat back system
