Hi guys, we run a 1.6 Eunos in a standard sprint class, but exhaust system is free to modify. Car already has a decat, what exhausts are known to give the best power gains cat back? Manifold has to remain standard. Many thanks , Lee
Cat back makes very little difference at all. The manifold can make a difference but you can't change that. Better off investing the money elsewhere - at best, if you spend a lot of money on a full system you might gain 1 maybe 2 bhp if you are lucky.
