I have the2.5 rush pipes on my sg along with the vh true duals.I had everything put on along with mapping and breather for 775.00.The sound is a very deep sound and it sounds great at idle.Best of all there is no popping when you decel.
ive had rineharts and rush and now going with hard krome t-rex true duals. i dont know but the rineharts I loved and you can get the chrome end caps for another measely $100.00
