Borla, Pipe Size, and K&N

Okay, I’m looking at getting a Borla Exhaust and a K&N Intake.

I’m wondering what Borla Muffler it is that everyone gets, which Borla sounds the best on these cars, and what is the size of the stock piping?

Also, I would like to get a K&N Intake, I’ve seen the Typhoon intake and was wondering if anyone else has this on their car, or if there is something better out there.

I really appreciate the help.

are you looking for a true exhaust or just a fart pipe? I have a borla proxs on my 2.5" trubendz and it sounds good to me, the stock pipe is 1 7/8". the intake at is the best for the car
