i've seen those things they sell at autozone that are tubing expanders but do they realy work? i've got a impact so if i have to use it i will. i'm just looking for a cheep way to do this so i can have a easy slip fit rear section with a "slip fit clamp" i guess you could call it (summit sells them). My CRX is currentally exhaustless and just starting it in the grage is mind numbing. I plan to do a 2.5in header back with a high flow cat (not just to be leagal but to quite it down) to a mangnaflow resinator then out the back to a ES oval. I want a good quite sounding car (obiously )

 

Just take it to the local muffler shop and have them expand a couple pieces for you, they should have a nice hydraulic expander

 

i used the one H.f. sells and it broke the 2nd time i used it. I ended up striping it out and that was with thin wall tubing.

 

i was watching american hot rod last night and they used one like autozone sells with an impact. except they cut perpendicular to the end of the pipe about 2 inches down, and it seemed to work well for a slip fit.

That would work, I saw that to. But I would watch how much you cut, or else you could have a leak. Why not just flange if back there ? I have dealt with a few slip fit exhaust systems and maybe its because I'm in Illinois but the slip fit always gets stuck and never comes out anyways.

 

or you can just buy one of those little reducer coupler jobbys at the parts store and weld it on.

I think the original poster can weld, but I think he just wants to be able to slip the exhaust over so he could pull it off later. I mean that is the only real reason to do a slip fit.

 

this is how I do slip fits. makes install super easy, weighs less, costs less, better clearance...its my favorite way to make exhaust connections. I just use the slip fit connections from the local parts stores like i was saying above.

What are you using for those little pieces of tube ?

 

probably just little pieces of tube from liek homedepot or something?

 

onePOINTsix (and anyone else), if you want some of those little weld-on reducers/slip-fit ends I can make them for you. I can also do transitions.
All parts are made-to-order, I do not stock inventory because I do these parts after my shop closes at night. (and that's my little disclaimer if your parts don't get there the next day).


Oh yeah- and this is my expander...

 

hey, adam... do they make those in 4" I.D?

Brandon, could you do a few pieces like that with a 4" I.D?

 

We can do up to 5" slip fit we charge 8 per expansions if you provide the material

 

I can do up to 24"..... (not to be entering a pissing contest with you, Casey )

 

Damn i wish we could do 24"!!!!!!!!

heheheh lucky you i wouldnt wanna have ti lift that damn tube though!!!!

 

The tube isn't bad but the segments are hell. One of my guys tipped over a segment from the 12" expander on a supervisor's pinky finger a couple of months ago and almost took it off.
I'll have to inventory all the useful-to-cars tools we have and get a list out there.
We usually only do jet parts.

hard hydraulic line, 1/2" I think on that one. I get it from a marine hydraulic shop near me in long sections and just chop it up on my bandsaw.

not sure how avalible premade 4" ones are but as you can see above having it custom made would be pretty reasonable. I bet NAPA could get 4" though sine they do heavy truck exhaust too.

 

wow alot of good responses to this, i think I'll just get the slip fits from a store and weld them on (have access to a mig welder) and use the bolted technique like above. thanks for all the help
