Default Custom True Dual Exhaust.. thoughts?

I am thinking about doing a 2.5 true dual custom catback exhaust with Porsche 996 Turbo dual tips.

I want to achieve this like the link below.

Anyone else here running 2.5" exhaust? Is it too big or should I go with 2.25"?

Looking at running 2.5 piping from the catback into a 2.5 magnaflow exhaust then straight back to tips.

i know you need a lil restriction to get proper backpressure for torque but idk how much or any relative info. i would think a stock engine would flow better on the slightly smaller 2.25 than the larger but let see what the pros say.

I agree, I was worried about the back pressure situation with a 2.5". I was hoping a pro can chime in and let me know if 2.5" would be okay or I should back down to 2.25".

What kind of back bumper are you going to have with that exhaust you want to do ? That video of that black SC is he on here ?


I was about to do the Job Design rear dual tips as you probably know already those are just tips but when I found out how much they want for it then I was like heellllzzz no.

I was thinking about running just one in the middle where the resonator is. It would be a dual inlet/outlet muffler

pipes from the cats leading to an x-pipe then to a dual in dual out magnaflow. of course it sounds better in person, i think there may be a little vibration when i fully rev it. I have an Injen intake too.
