Who makes a good true dual exhaust for the 4.6 extended cab? I checked out Truckperfrmance.com and all of their kits are single muffler style. I like the sound of the Gibson but it obviously isn't going to flow like dual exhaust. People seem to buy it because of its sound. I think the sound fools people into thinking their truck has gained more power than it has. If anyone can give me a good site I would appreciate it. Side exit in front of the rear wheel is not an option for me. I live in an area with 4 monthes of winter. Ford actually recalled the front exit because it was causing the rear brakes to freeze up. This would be extra bad on a 2000 model like mine due to the rear disc brakes. Thanks. Jay.

 

I've never seen a ready-made "TRUE" dual system for an F150. They may be out there, but don't seem to be common. Mine was custom made by a local shop.

#7 covers this. Muffler shops seem to consider this a grey area in some places. From what I can find, the Federal law states the portion of pipe where the cats are cannot be modified. This is the whole headpipe/Y on these trucks. It states you can do duals if dual exhaust systems are offered on similar chassis/models(which doesn't exist in F-150s). The confusing part is where "other vehicles" which come with one cat want to add another to have true duals. I was told this is why NOBODY makes a "true" dual exhaust cat-back kit for F-150s. I'm not an expert, just passing on what information that I could find.

Thanks Max! Interesting info. I especially like the last sentence in #7 where it's OK to modify the exhaust IF the manu****urer does it on a "newer" model. So, all we need is for Ford to put duals on the '02 trucks & we (I'd) be legal!

 

are lightnings true duals?

if so then there is ur answer
a f150 model with duals

and it would be legal

if not then just go down to a kinda 2nd rate muffler shop and they will do it for u
mine will be done at a local shop when im done
