I recently went to look at my exhaust system. Seems that the original Magna Flow - dual cats - single - muffler - dual exhaust/tips design (prior to purchase) ran the CatBacks directly under the rear leafs. Fuq, as you can imagine. What happens: when the truck is lifted in the air, or when i run over a curb or somthing, the axle/leafs drop down AGRESSIVELY on the exhausted, and ultimately destroy the hangers. so im let with a tail pipe swingin in the wind like my grandpa pissin on the barn (or something).

I am going to get the rear half of the Cat backs re routed. $150 bucks. I just want him to cut the angles out and add new straigts, and replace the angles.... pic to decribe:

 

SORRY - much better drawing - including proposed layout. This new layout will cost roughly $200 TOTAL - rather cheap I think - its a guy I work out with.

I know that realistically I should start over from the muffler OR EVEN BETTER the CATS. but I would really like to keep this at the asking price.

I know NOTHING about trucks. I've done a few mods by myself: CAI, Programmer, Wheels/Tires, change oil, wipe the dash down, vaccum...you get the picture.
I really wanted to do this by myself. Hacksaw, coupllings, extensions, etc... Yes I know when I take it to a professional - I would possibly get laughed out. But then I dont get my fingers dirty....thoughts?
Then again - how much hard work is it to do that 'minor' work?... is it realistically gonna take me 2 weekends and 5 Tshirts of sweat?

 

why are the cats that far back?

 

new layout

 

rough estimate... by no means is this to scale. I guess im more concerned about Muffler back right now. And if I would just COMPLETLEY behoove me to replace everything.

I break a hanger every month. So im under there often -fuqers.

The guy helping me actually wants me to just dump EVERYTHING off after the cats. FL - doesnt have emissions laws.

 

Your second design may have some interference issues with your spare tire, if you have one.

 

i see split exhaust with H pipe on some trucks, the H pipe is before the rear drive axle so interference is no matter issue! If it is 4 wheel drive, look into something along those lines, plus with a 5.4 with split exhaust, you gain better sound, better gas mileage as well as less back pressure! Hope that helps a little

 

Just that little rerouting work for $200, too much IMO.

You could get a whole new catback (tips, muffler, pipe and all) for not much more than that.

 

As long as it's after the cats, you're not messing with emissions. Emission laws are Federal, whether or not you get inspected is determined on the state/local level.
