Straight Piping
look in your owners manual ---- $10,000 is possible.... not probable, but more risk than I wanted to take for the limited benefit of taking the cat off....
(fyi- some older member tested before and after cat removal and noticed marginal differences other than noise )
I run the MBRP cool duals, When I installed the kit I looked at the muffler, you can see right through it! No restriction, just sound modification.
Inside the truck I get a nice roar that is not annoying. At WOT the truck is really loud. Sounds great. You can always pick a Ford out by the roar, they have a distinctive sound.
Mine is a 2003 and the turbo sound is like a 747 winding up for take-off
friend of mine had his 2003 straight piped. was nice until he got married and kids. also on long rides it would kinda get annoying (the screech i mean). but man i could hear him long time before i ever saw him coming down the road.
