Flowmaster's on my 2007
 

I haven't been here since before July 1st. First of all, I got my Flowmaster 40 series installed on my car and it sounds super nice (video to hopefully come soon). It turns a lot of heads when i'm cruising by or start it up in a parking lot.

Anywho.....anyone know about how much power/torque the exhuast added? If any at all? Had the resonator removed and new piping all the way back to the mufflers.

Its hard to tell without Dyno testing a vehicle.

Probably very little. Depending on your other mods. What piping did you go with?

I told the guy shop 2.5" but idk. It looks smaller.

Mandrel bent?
