came across 346 lsd out of a vt ls1 for a good price n couldnt resist to buy and 2 1/2 inch cat back dual x force system.. i know the basics eg: 2x cat, need vt tail shaft and some advice would be greatly appreciated on sound of exhaust system on v6 vx.. the shop would be doin that job but other people`s oppinion would be great before installation should i keep or get rid of pipes???

Ps..

bought the exhaust for look and sound if sounds crap, surely wouldnt be hard to sell???dual 2 1/2 inch x force of a vx ls1...
