Only issues are with cracking which can be hit or miss with buying used online, I had good luck with what I bought for my '63. If you want new get ones for a 70's 'vette or go with speedway's version with 2 1/2" outlets for 54 a piece. Or do you specifically want the angled 2" outlet?
Looking at them both it seems on the corvette the pipe would hang down in the axle area and the P/U would place the cross pipe farther back. And feedback on this area? On a daily driver do I need the 2.5?
