My car is at Orbit right now, installing and trying Porro's old headers and than removing the side mufflers and Sharky and reinstalling the stock muffler. We will find out if it is livable on the street, otherwise I'm going back to the current setup. Not really hoping for HP, just weight out the rears.
Porro's headers were 16.5 lbs (no cats) and center was at 17.5 lbs. So I'm hoping for approx 30 lbs weight loss. But as stated before, if it drones or is too loud on the street, I'm going back to stock w Sharky

you need full cage with side protection when you run carbon doors. even at de, if you had the misfortune to get t-boned, then the door on it's own offers no protection.

anyone know what the weight saving on some carbon doors would be? I bet its major. Doors are heavy. I know in my previous cars they were a decent weight anyway.

Just picked the car up, did not take the stock headers with cats or the side mufflers with me so I couldn't weight them. Added to the car were M&M headers at 16.5 lbs, stock rear muffler at 17.5 lbs and cup car elbows to connect the headers to the stock rear muffler. Removed were Sharky exhaust, stock headers with cats and the side mufflers. I think I saved about 35 lbs from the rear of the car.
On the street the car was still perfectly drivable from 2500 until 4000 rpm, but it is impossible to go to 8000 rpm on the street, because it gets wayyyy too loud and would attrack the popo from every county on the east coast. But under 4000 rpm it was not much louder then the Sharky exhaust, with very little drone below 2500 rpm, which is where my car is only when taking off from a light.
It feels like it lost a little bit of torque down low, but I was too afraid to attrack unwanted attention to see if car felt faster in the higher rpm's . Dyno and/or track will have to prove that.
p.s. Baller/Eddie picked me up in the GTR, that thing is stupid fast, even in stock mode.Thanks for the ride Baller
