Guys make over 800 hp with 2 1/2" exhaust.. Doubt that a 450 hp stocker would benefit for 3"

Exactly how many “street” cars have YOU built with 3 or 3.5 inch exhausts that lost power?

I build nothing with less than 3 inch exhaust. Ever. And they aren’t down in power.

The number one killer of tuned exhaust is piss poor cam timing.

Blow the LSA out for idle “quality” and you can bet a 2 inch exhaust won’t make a pinch of **** of difference.

But get the cam timing correct and that tiny exhaust will kill it.

Its near impossible to see that in 2023 we still have guys stuck in the late 70’s and early 80’s thinking.
