I reakon most exhausts ruin the shape of our cars that's why mine is dumped back before the diff. However that ute with the twin pipes would be mad with a hi po CA powering it and flames to boot during every gearchange or backing off of the accelorator.

Big pipes are for cars that have enough power to need them. That's got me thinking again though as I have a set of Arrow extractors I was going to throw on the car, I think the collector pipe diameter is 2 inch but it may be bigger
