Has anyone had to drill out the holes on their SMSP for the H22 to get it on the car?

Long story short I've had no time to even attempt to put the header on the because of school and various other time consuming problems. So my dad took my car to get this installed to a muffler shop that does all work for his cars and such. Well I got a call from them before I headed off to get the car saying that can't get the header on because they can't get it in place, so they are saying they need to the top part to a machine shop down the street to drill out the holes a bit so that it has a bit of room to be able to install it.

Now I vaguely remember a discussion about because of the tight clearances of these headers and other high end headers that work like this is sometimes needed to install the header if the motor is still in the car because you just can't get it in place.

Now I don't think the shop is trying to run up my bill and believe me I'll be making sure that it's not a scam but has anyone had a problem like this while installing an SMSP on their H22?

But I just wanted to see if anyone else had this problem, or if I just need to go down there tomorrow on my day off and show them how to install a damn header(not really but you get what I'm saying)

I searched for the thread but the title really had nothing to do with actually fitment so I'm coming up with nothing relevant

 

i would first contact Dave "SMSP" on here.

 

When I installed and uninstalled it was a very tight fit. Just took some time to get it in there but nothing had to be drilled out.

 

expletive I think I have a 4th gen header...

EDIT: ok I'm sure i have a 4th gen header because who I got it from had a 4th gen.

anyway I found this thread:
https://honda-tech.com/zerothread?id=1488679

jist of it is I need it lengthend to fit my 5th gen, but lengthend which way? horizontally or Vertically? and if Vertically how would an exhaust shop go about doing that? making a extending slip joint?

i wouldnt modify the header at all
id get the muffler shop to modify your exhaust if anything.

 

i was thinking the same thing, i thought the diff between a good header and a regular header was the angles. Even if u could modify it, I would rather just sell it for the price I got it at or take a slight loss on it, then buy the 5th gen one.

good luck

 

the SMSP should not need any modification.

i had to dremel a little off the xmember to get it to fit. After i dremelled a few mm of the xmember, i seam welded it to make sure.

I don't spec large holes in the flange so that I can control the location of the ports on the header with the ports in the head. Some headers actually have so much clearance in the bolt holes that it will float around and when you tighten it down you have no idea where it ends up.

I use an H22 head and block for my jig, the header is on and off the jig a couple times during the build so it's fits the head I have. The shop may just be installing it cocked a bit and that may be giving them a problem but I would NOT have them open the holes up.



As for 4th or 5th gen, it doesn't matter. The header won't "fit up" to either OEM system. A new 2-1/2" cat or test pipe with donut joint is required to be built.

Yup.

Compared to the OE exhaust system my header's collector ended fairly low, to the right, and short.

The exhaust shop will probably have to trim the crossmember a bit.

But I would listen to Dave before me

The clearance with the cross member is tight. Tighter on cars where engine mounts are older. Some guys will clearance for the 2/3 secondary just for some added insurance. But big tubes need more room.

 

I did not have to do anything to the flange on my original SMSP header. I have not installed my second one, but I'll try to check soon.

Yeah. I could install mine against the crossmember, but it would end up pressing against it.

I'm definitely pretty attached to my header. Even if I unbolt it, it won't come off the head
