Hey everyone I'm looking at similar. Catback exhaust.
Factory ls1 vy ss
Only mod is k&n pan filter
In the future I'm keen to get tri-y headers
Can get rage, rps or coby though a mate of mine cheap.
Rps catelog
I like the look of the 4th one but is twin 3inch too large?
Given that factory is 2.25" (I think) then single 3 is actually smaller cross sectional area, is this an issue? Twin 2.25 is 8sq inches, single 3 is 7sq inches (12% smaller), twin 2.5 is 10sq inches (25% bigger) and twin 3 is 14sq inches (75% bigger).
Thanks
Taylor
