Im running a 14b and have a 2.5 in down pipe, i bought the car with the dsm setup but the guy put a 5zigen fireball aon it and the piping is only 2.25 so i'm guessing there is quite a bit of back presure. any good suggestions on an exhaust i wanna replace it asap. any one want a fireball?

 

what motor?

 

d16z6 but i have recenlty had problems with the ol z6 so i might jdm d15b turbo
either way what do suggest for the exhaust, oh and i dont have emission requirements where i live

 

then go open downpipe.

or full 2.5" exhaust and grab a cheap summit turbo muffler for $20

 

thats exactly what i'm doing to my z6. summit has a great deal on an aluminum car jack too that im gonna order
