you went with the standard cats? and single exhaust instead of doing a dual exhaust? I understand your not wanting to make the truck a performance machine but...
Supercrews can't even have a legit true duals cause where the gas tank is, to do true duals you have to run the drivers pipe about 5ft extra length so it's actually not even beneficial. As far as cats hi flow cats aren't anywhere near the money and cost, hi flows for what like 4-6hp? Not worth it at all, priced out the standard stuff cost 1/2 the price of the hi flows. I'm just gonna do Cali duals out the back
Im a little surprised you dont have exhaust on it already. What kind of muffler are you going with? Im gonna scrap my true duals and run 3" single pipe with magnaflow back when I swap in 4v..
had all 4 cats gutted, with a single glass pack dumped under the bed. Sounded good but the noise got annoying after a while and especially way too loud for a 5k mile trip to ak, not to mention I dont like the smell without the cats. gonna go with a summit street strip chambered muffler, same ones I have on my blue mustang.
