Exhaust Choices
 

Im gonna be honest, i want my truck louder. I can get a 5" for $300, or cut the cat?? Whatcha think??? Will the 5" flow alot better, cause i do tow alot.

It will lower EGT's. What HP are you running.

straight pipe it

I tow on the low setting, 65hp i think! I dont have a muffler now, i dont plan on any other power mods

Your 4" should be fine. I'd keep the cat and look into a resonater , if you have already done away with the muffler and still want nore sound . Becareful not to get a drone while towing.
