Guys,
I've decided to do my own duals front to rear exit.

All stainless, 2.5", X-pipe, electric cutouts, muffler undecided leaning Magnaflow dual inlet/outlet, over the axle dual rear exit.

Plan on buying 2.5" stainless mandrel bent pieces like this Ebay Pipe and chop cutting /welding where I need. How many pieces do you guys think I would need? I'll also get a couple longer pieces of straight.

I am also tool poor when it comes to this project and if I count the cost of tools I'll probably have $1500 bucks in this exhaust.

Tool list I have. Small gas mig welder. Chop saw. Figure any slip joints I'll put in I'll just take them to an exhaust place and have them done. I have miscellaneous saws, grinders and such. What else tool wise would I need?

 

Sounds like a good plan Have you decided on routing? The transfer case and crossmenber really make it a fun job

 

I don't think I will attempt the routing like yours but I will look at it. I saw the pictures you put up and I still don't see how he got that pipe down the drivers side Think I will wind up running both down the passenger side.

 

I am thinking of doing mine also. I dont think it would be that hard specially if you dont need to go over the rear axle. Im going to run mine out the side just behind the passenger door with two rectangular tips. All the dual exhaust setups ive seen in person have been ran down the passenger side then after they go over the rear axle they seperate and go to each side of the truck to fit the tips out the back. If you already has misc pineces of curved and bent pipe there isnt going to be many tools requires.....a grinder, welder, saw that should do it all pretty easily.....unless you want some easy connect joints like ball joints or something.

 

i would reccommend tape. after you cut two tubes u want to join together. tape them together and cut holes where u want to weld it, just to tack it together. makes it much easier to get a perfect joint between the pipes. then remove the tape and weld it completely.

 

Good idea!

 

Sounds like you got yourself a hell of a project! I would recommend at least 2 clamp joints per side from the y pipes back. If you go to a muffler shop to get some slip joints made, it's called a swedge. There's some places you can get a J piece that has a 90 deg, and a 45 deg, and a straight all in one piece. 2 of those, some straight lengths, and maybe 2 more 90's should about do it. Good luck, and keep us posted!

 

Can't seem to leave it alone. I'm not happy unless I'm working on it. Getting bored.

The J-pieces you mention is what I linked to up top. Kind of what I was thinking. Couple three of those and couple more 90's. I'll also have my current catback I can hack up for pieces.

I'll probably head out tomorrow and maybe come back with a welder. Already have most of the part sources lined up. It will take me a few weeks to get them together. It will give me some time to practice up with my welding.

 

That's definetly a cool project, it feels good to know you built the whole thing yourself!

I built a slip fit exhaust that used OE style band clamps, and it is very difficult to pry apart. I also had to buy a tube expander to get the joints opened up before re-installing. I used Flowmaster ball flanges on my last project and they worked out great. They allow some mis-allignment of the pipes at the joint and seal up completely without the bolts needing to be very tight. The downsides to the ball flanges are, $50/pair and only available in aluminized steel as far as I know.

Good luck on the project!

 

Yeah it will feel good to do it myself. Most everything I've done has been bolt on stuff. Just hope I can get it done.

Thanks for the input. I'll have to think about the ball flanges. The dynatech y-pipe that I have on it has a couple slip joints with the wide stainless band type clamps and they work pretty good. I've had to take it apart a time or two to get the tranny out and it came apart nicely.
