Default Those with home-made true duals....come inside

Any advice for making my own home-made X-pipe setup? I have Pacesetter LTs with 3-bolt collector flanges.

I ordered from Jegs:
3" to 2.5" flanged reducers
2.5" universal X-pipe kit
2.5" Dynomax bullets
2.5" turndowns

I planned on getting everything bolted up/clamped together, with hangers at the rear seatbelt holes, tack-welding the slip-fits, taking the system off, and then welding everything completely.

Is there anything else I would need besides hangers?

Any advice would be appreciated. Thanks

I made a 2.5 kit for my SS a while back, seems like you have everything needed, you may want to look into a heat shield of some sort for the fuel lines, when I did mine, I wanted them tucked up high because at the time I was lowered, so the pipes were close to the fuel lines, I used some stuff my dad had in the garage, it some sort of a heat wrap, you could use header wrap if you wanted to wrap either the lines or the pipes.

I have a bunch of header wrap that I never used....so I'll use that. Thanks

Also, if it's THAT close to the floorboard, it will probably smack it when the engine torques, so I might flatten that pipe a little bit.

They were hooker long tubes. i used a Torque Tech universal 3" x pipe kit w/ bullets. I tucked it in as high as possible and have not had a complaint yet of it hitting the floorboard.

You can 'flip' the fuel lines on the brackets to get more clearance. A must for duals. Just flip the two fuel line brackets(in the DS tunnel), so that the lines are above the mounting screws instead of below. Gives you about 4-6 more inches of clearance.

I'm not sure what the kit comes with but you might want to pick up some mandrel prebent pipes 45 bends. I ordered all my pipe without a kit so I needed a lot and then just cut them to fit.

Yes, some require a little more 'encouragement' than others.

You could probably buy a 2.5" U-bend and cut your turndowns out of that and save a few bucks and have a little extra pipe and part of a bend also.

Besides flipping your fuel lines, you need to know that under the driver seat, you will need about 1/2" clearance especially on the drivers side. And at the tunnel you will want to tuck the muffs tight into the tunnel if using bullits and go about 1/4" clearance and you will have no clearance issues. Also you can use the heat shielding from the rear where the stock muff is and fab a heat shield for the fuel lines as i did. You will need less clearance if you have poly motor mounts.

Just undo the mounts for the fuel lines and simply flip them over. Then rebolt them back up...This pushes them up higher into the car.
