exhaust

[alliston]

just having a quick look through the forum and found an article on exhaust eg best size shape etc etc.i was wondering on what is good and what is bad. mine is currently 2.5 straight pipe form the flexi straight to the back of the car. i have been reading on alot of people doing the side exit exhaust. is this better for preformance. should i cut mine and bend it to the side in front of the rear wheel. i have a 2nd gen 3.0 ssrg

any help would be much appreciated cheers
