Hi Cartmale.

Its been a while but I figured I would respond to help clear some stuff up.

Engines needing backpressure is a myth.
On an NA car what happens is people kill the gas velocity and scavenging effect of a properly working exhaust system. They do this by using too large of a diameter pipe, or just a badly designed system overall.
On a Turbo car there is NO scavenging at all as there are no exhaust pulses after the turbo, therefore its more forgiving.

Cutting holes in your exhaust wont gain anything other than noise, and depending on location can be detrimental as hot exhaust gases are flowing out of those holes now and can melt stuff. Make sure its not expelling hot gasses at critical stuff like brake lines or plastic that can melt or catch fire.

From what I have read the stock exhaust systems on these things are pretty good, if you want to make it sound a little better toss on a free flowing muffler or straight pipe, you will NOT hurt anything by doing so. Have an exhaust shop do the welding imo. You will likely have ZERO gains with with just a muffler because factory calibration is delivering x amount of torque at a percentage of throttle and wont give you more. Tuning is really required to see any real gains.

Exhaust note is all personal preference so straight pipe, or muffler away. I personally don't like the overly loud high pitched drone that a straight pipe gives, I would go with a good Magnaflow muffler to get a more refined sound, but again its all personal preference.


Happy modding
