Most of the companies (AA, B&B Triflo, etc) show the dyno chart before and after...and they are pretty reasonable. I would check out their websites:Jayman864 said:Has anyone done a dyno after adding a performace exhaust to test the gain??
Sure, it is a nice mod, you will notice a difference, and if you plan on seriously modding your car..necessary. But don't think that putting an exhaust on your car is going to make a neck breaking difference in power---it's not like you'll be able to smoke Camaro Z28s or M3's or what have you. The look and more importantly the sound of the car will be completely changed....it will sound much meaner and sportier.Jayman864 said:so shouold I get an exhaust or not... lol
Well do you want a loud exhaust? quiet? Everyone has their opinions and preferences. I wanted an exhaust that was really quiet when driving around town...but was deep and throaty and somewhat loud when you really nail the gas....I got the the Active Autowerke and I love it. Seriously, when you are driving around town, it sounds completely stock. And when you floor it, it sounds completley different!Jayman864 said:so... what should i get?
