After some advice, the sports twin and single exit exhausts, are they too loud for track days? What DB's and which makes to avoid or choose. Thanks in advance.
Thanks for the replies, the twin tail rear box on the car is extremely noisy, the packing must be missing. So I think I'll replace it with the colbalt twin tail system then. I think the existing system is fubar. Getting it ready for a track day at Brands on Friday, roll on spring!
