I was looking to do some exhaust upgrades to my 98 5.7 vortec. If the stock dual size is 1 7/8s, the crimped bend on the head pipe has got to be 1.5 maybe less. Is this not killing power? I am pretty sure my wifes 2.5L toyota camry has 2.25 pipping.
Whats up with it the small size? I always thought exhaust piping should be no smaller than 2.25 on anything.
