How would you fix a bashed JDM 4-1 header. Lets just say the bottom 2 collectors have been reduced significantly. How would an exhaust shop fix this if at all possible?

 

i've read before one way was to have a ball on a rod of some type, heat the **** out of the dents, and try to push them out from the inside through the collector. make any sense?

rob- who would rather just buy a new header

 

If it has been bashed significantly enough to the point where it's impeding flow, I'd send it to SMSP and ask him to cut the damaged portion on and weld on a better collector.

 

drill a hole and use a puller like they do on body panels. Or cut out dent and weld new plate over it.

 

Quick responses and thanks for the help.

your torque must be crazy yO!

 

when I hit a rock in the road with mine it actually dented it so bad the metal split, in that case I had to have the damaged portion cut out and have a new section welded in... not to expensive once it was all said and done (around 50 or so dollars) but it was just a major pain in the a$$. In your case it seems like a small hole and a slide hammer should do the trick.

For the future I would suggest getting a skidplate or some sort of protection for it. I got mine after the accident from fastline performance.



let us know how it all turns out!!

OEM or DC?

 

If you're going to make a skidplate, it'd be preferred to have it bolt to something other than the header itself.

What's going to prevent the skidplate from being smashed into the header?

 

in a severe impact... nothing; but for the everyday scapes and dings it works great. Something is better then nothing, I guess.

I'd just go all out and have Dave make one of his custom headers..

If you damaged your OEM JDM 4-1 or DC 4-1 at least it didn't drain your pocket like the Jay DEE MM (Spoon, Toda, etc..)

 

how much does a header from SMSP run?

it looks like the skid plate hangs a lot lower than the header... that true?

 

u got the web addy to where u got the skidplate... i had it but cant find it anymore, ima go ahead and order one.

thanx

 

Curious which it was. Seen lots of DC's bashed due to clearance and no OEM's to date.

Thats my dented OEM JDM 4-1.

 

holy $hit!!

 

I banged up my Spoon header pretty good...wish that Fastline plate fit it, but apparently it's for 98+ JDM ITR headers only. Doh...

Ohhhhhhhh Snap!!!

 

 

reid do you know the bed of nails trick???
you know the one where a guy lays down on a bed of nails and have ppl stand on him... do you know how that works well the skidplate is kind of the same thing..fastline does say that these plates are very strong....
