well everyone i bit the bullet and got the rear section of the ODC exhaust changed, as i wanted quad tips on it, but was unable to do that unless i changed mufflers also, so i had that done, i was worrying about the noise difference, but it is very slight, nice note at idle and no sound when cruising inside the vehicle at all, which is what i wanted, got it all done in polished stainless, biggest thing about it, is the difference in power is unbeleivable, if you look inside the stock mufflers the pipe size drops to three quarters of an inch, not good for making power, it accelerates so much better and in my opinion alot smoother, i cannot beleive the difference, dont think im just thinking this either, im no stranger to power, my other car is a 10 second holden torana. i will get some pics up, but i can say i highly recommend it to anyone thinking of doing this
