Thread: Speed Daddy Headers Crosspipe Fix

04 Pontiac Grand Prix Supercharged: Hey what's up everybody. I ran into a bad Crossover pipe with SD Headers.

Finally found a person to weld for me but was told to make a "cut" on the Crossover pipe so I'll be able to bend it by hand where it'll fit and bring it back to him so he can weld the cuts for me.. Not sure where's the best place to cut or how many cuts to make to bend... Not sure what the welder will do. Guess I'll be molding crossover pipe for him since I have to drive 3hrs to my car and come back with the headers to be welded. (Car sick 3hrs away from welder & headers)..

Also was told to cut the crosspipe in half and add a flexpipe so I can flex it to fit.... Not sure what size flex for crossover...

Was given those options....

2 questions:

1. What you guys think will be the best option?

2. Will I be able to wrap all flex parts with this titanium wrap or will I crack pipes/welds by wrapping?

Need help. Pics below

That's really strange. I have these on my gp and never had an issue with alignment like this. And I've installed like three on friend's cars all no issues. Oh well, it's China, guess their quality control isn't the best.

I can't answer as far as the flex wrap, but I'm sure Scotty can weigh in on that!

Tried everything. Even had qualified mechanics on hand help. Loose front, loose back and all combos. Have to figure out a way to fabricate now

you could try a pipe in the pipe to bend it over, just watch you dont bend the crap out on the end of the cross over pipe.

Cut and bending procedure will be done outside the car for sure. Outside cut made more sense to me as well. Don't know why he was telling me to cut in the inside and said to leave him some steel to work with... Odd..

Scotty chimed in on my problem a few weeks ago I believe. It's hell that they won't bolt on and fit. Trying not to mess them up ha... But just thought to myself that if I can wrap the flex it might protect them even more idk. And than again I was told to keep the wrap at least 2-3in away from the welds because the isolated heat will eventually crack from the welds....

I'm just so close on getting my car on the road. 1st time modding and it's 3.5 Pulley with supporting mods or bust for me lol

for real tho, id be on the pass side fender grab that header on the cross over and pull on it, get a friend in on it too if you cant make it bend. im a monster in my own right, you may not be 6'6 and 260 lbs like i am lol

Lol! 5'10 165 lol! Bench 260 max but this header IS a different monster. Let me get to fellas like you and let me take a "step back little fella" haha

Exactly! Nobody wants to help. California rules [emoji57][emoji19]... Probably need to invest in tools now. All I need is 2in left and 1in down. Simple ha.. China made...

MAP Gas Torch huh, I might as well purchase me one and get'r done. Header wrap is off in the meantime. At the 2nd bend here right?.. I'll YouTube how to torch this bad boy. This crossover is giving me hell

Heating it up will allow the whole tube to flex and bend enough to move it into place. A MAP gas torch is just a propane torch but way hotter. Heat it up all around and it see what it's like to work with.

About to get after it!

Well fellas ha.. The bend is official. Kinda pinched it at the bend. Not sure if that pinch from a round circle, to a vertical oval, will restrict some of the exhaust but it was worth a shot. I did the bends blindly so I wont really know the actual fit until I get to my car. All I knew was I needed 2inches to the left and 1inch down haha.

Like stick the rear of the pipe in the back header, heat that bend up and then push it into the front header to make it fit.

Yeah, I was looking to do that but I wasn't getting the whole surrounding area red hot for the bend.. Even with the headers out, that slight bend took a minute and even longer because I seen I was mess'n up the pipe a bit lol.. Had fun though haha
