xDownshift:Thats what the NFS series is for. It's a racing sim, where they allow you to customize your car a bit. It's not ABOUT customizing your car. I've done replica paintjobs, but I think that's a bit more understandable than wanting a huge exhaust. Do you ever look at your exhaust in a race and complain? If you do, chances are you SHOULD be playing NFS.
And, P.S.
You lose a lot of back pressure with those huge ass exhausts.
Please tell me that was sarcasm. Back pressure has so little to do with exhaust that it is laughable when people make this comment. Yes if you put diesel exhaust on a 4 cyl engine you will lose low end power and your top end will suffer also, but if anybody is that ignorant then they deserve the consequences. Increasing the size of your exhaust (with in reason) will only help your performance. I mean hell, I gained close to 25 horsepower and over 30 lb/ft just by switch my stock 2.0" exhaust to 3".
Thank God this is not a tech forum because there's so much mis-information about cars going on in here that I feel I am getting dumber by the minute.
