Alright! im getting brand new chrome exhaust manifolds and i have a few questions. Would I okay getting manifolds with a 2.5 inch outlet and then have an exhaust shop attach it to the rest of my stock 2" exhaust? Do the crossover pipes on stock dual exhaust systems really do enough to justify getting them? and how universal are exhaust manifold flanges, because the 2" ones i have currently wont fit the budget.
