welp i got a repair order for my straight pipes -_-. so i gotta switch it up while quieting down the sound. im looking at OBX evo replica mufflers. Theres two that i want but one more than the other. the one i want more is more for looks but has a 2.5 inlet but a 4.5 outlet and im fearing that 4.5 outlet will make it too loud.while the second one isnt as appealing to me as the first one i still like it and it has a 2.5inlet and a 3.5outlet. They both use a 3 layer design using aluminized steel, rockwool fiber glass, and stainless steel wool for optimal sound reduction with SUS 304 Stainless steel performance resonator & tip will the 1' extra outlet make that much more noise or would i be ok getting the 4.5 outlet. (no resonators currently in exhaust)
