Well just got my exhaust done a couple of weeks ago and its sound awesome but i got one problem. When im at WOT and hit about 3500 rpms to about 4500 my truck hicups or thats the best way i can describe it. It will stop acerlating for jsut a split second then be fine and then will do it maybe one more time in that band and then be fine. It doesent always do it but most of the time. At all other driving speeds it is perfect even if i rev it up in neutral it still doesent do it.

I've had my computer re set to maybe pick up the exhaust and that helped but it is still there so now im confused and out of ideas.

I was wondering if maybe i needed to get a custome tune for it, but i've heard of people of putting straight pipes on my style of truck and not having any problems.

By the way i put a SLP loudmouth II muffler on and y'd it out to 45's never touched the cats or anything else.

Thanks
