SR SR20 Running OEM Exhaust

So I have a 3 " pipe all the way back about a foot out the car... sick and tired of it now and doesnt help when every cop looks your way cause your car is unbearably loud. SO my next question being how bad will a stock exhaust be for my sr with just bolt ons and running 12psi... If im overreacting please forgive me I just dont know if running a smaller diameter of pipe will really effect the power of the car. I just dont want to hear BAHHHHHHHHHHHHHHHHHHHHHH everywhere i go now


Love from texas

Yes, it will. Quite negatively.

Get a 3" exhaust with an actual muffler on it. One that's JASMA certified. I have a 3" Fujitsubo and it's very quiet. Supposedly the A'PEXi Noir exhausts are really quiet as well.

I have a ebay exhaust and it sounds quite, it can get loud when you get on it but thats how it should be with any exhaust. Im running empowers resonated CAT with the ebay 3' exhaust. I have only spent about 220$ from what i have listed up there and I have never gotten pulled over for my exhaust and I live in Dallas? hope that helps
