exhaust question for B16 guys

[BOLricoNY]

I already have a stillen axle back and was looking to get a catback for my SPEC. Magan Racing has a cat back for the B16, but when looking at the specs it has a 2.25" inlet the same as the stock exhaust, I know it's the same as stock because I measured it, anyway whats the point of MAGANS catback if it's the same as OEM. Maybe I measured wrong can I get a second opinion, PLEASE! thanks

2.25 is a proper size exhaust for our cars, anything larger you will lose back pressure and torque. anything bigger is just a waist, the difference is going to be in the bends and the muffler/resonator combination.

Yep. I agree. Its pretty much about the resonator. You are going to gain better sound quality and depending on bend and flow performance. 10Hp at best, give or take.
