Thx mrizzle... they weren`t cheap but nothing is nowadays. I did have to use a wooden hammer and a wooden ruler just to tap the overlapping edge neatly and flush (10 min job)
Also inquired to 3 performance exhaust custom specialists and waiting to see what they can do although not sure if I wanna cut the rear valence or buy the pre cut one from rcz performance, I guess I`ll see what exhaust systems they can come up with. One of the specialist has over 20 different tailpipe designs hehehe,
