I'm really wanting to order a downpipe from zzp...but i'm a little confused on which one to order...i know i want the bolt-on...but is it better to get it with a hi-flow cat or use stock? and if i order a 3" bolt-on with cat do i need to order a u-bend delete as well or does it already delete the u-bend? thanks for any help...
