Like the topic says, how much room do you have between the oil pan and the header? I think I have identified my problem....I can only fit my pinky....BARELY, between there...does this sound normal to you?

 

Anybody...a pinky between the downpipe and oil pan must be too little clearance...

no, thats fine.. shouldnt be a problem.. I know Dave at SMSP builds his headers very close to the pan, for max ground clearance, with no problems..

Oh yea, what problem are you having again..?

 

Well the ACTUAL problem is that when we installed the DC SS header with engine into my car I found it to be about 1/2inch to an inch TOO SHORT to fit to my stock cat!

I didn't have time to do anything so I just hauled it together really hard. Like I can't move it at ALL with my hand underneath the car. Subsequently the exhaust/header is hella tight...and this is with the car off. I'm suspecting when the engine is torquing backwards on acceleration something really bad is happening...it took a week to surface but I'm getting a horrible noise from about 3000 rpms on getting incresingly louder as I accelerate...on deceleration everything sounds kosher, just when I accelerate...

Perhaps I've seperated the the internal piece of the flex pipe...and broken the seal on the 4-2 part of the header or at the cat, because I hear a rattle as well as air turbulence....I think it all has to do with the entire exhaust system being too tight and consequently taking all the engine vibration and torquing....and the car has a ton of torque so that doesn't help. Think that sounds about right? Getting it lengthened tomorrow

 

sounds like you defintly have a leak somewhere, and a tight exhaust system will do that, another thing you can do is slide the exhaust stytem as far forward as possible in the hangers, they should move more than 1/2"

 

Actually I'm having them put this in http://www.quicktimeperformance.com/qtec.htm

So after my header I will have a Y-pipe kinda thing with one going to the cat, and the other going to the electronic cutout. So at the flick of the switch I go from regular exhaust to straight pipe

They move the entire exhaust back and cut material out of the midpipe, so I'll just get them to make it up there. I just hope the header isn't damaged...it's sound terrible...but if I accelerate just right it sounds ok...some I'm hopeful

you can find exactly where the leak is simply by starting the car (with engine cold) and have a friend cover the tail pipes with there hands (this is why you want the engine to be cold so the pipes aren't hot yet) and you look/listen around and find where the hissing is comming from. If nothing else you can find out if your headers are okay. Just my 2cents

 

Yeah but I don't have time and it's multiple issues...I'll leave it up to the exhaust shop to fix tomorrow...then I'll know more

 

I have the DC CC header on a Base model 5th Gen with the bracket removed. I can barely even fit my pinky between the two. When the bracket WAS on there definitely was more clearance.

 

Bracket is removed on mine too

 

UPDATE:

Okay I went into the shop today....the flex pipe on the DC is FUBAR from me hauling the cat and header together so tight.


However, this opens up a new opportunity for my electronic straight pipe! Right now they are hacking off the DC at the flex pipe and inserting a civic/integra style spring joint, which takes up much less space. THEN, within the 10-12 inches between the cat and the spring joint, they are creating a V type pipe, one to the cat, the other to my electronic cutout, should work pretty good. I'll take some pics tonight once I get it working. Straight Pipe at the flick of a switch

 

I had the same problem when I installed DC headers on my car. It was to short .5 - 1 inch. The entire exhaust was pulled forward because of this.
I also had a noise surface because the exhaust clearance to the heat sheilds at the back of the car was thrown off due to the exhaust being pulled forward. It wasn't touching all the time, just under certain conditions.

 

Yeah I think I have it tracked down...and my DC header has been hacked all to hell now

 

You would have to have cut it for the V config.

 

yup I would have anyway...the cutout is done...just got to hook it up now

 

One header tube touches my oil pan... Will this cause engine problems?

I've got a JDM ITR header, B18A1 oil pan... Any suggestions?

Theres no vibration, my main concern is engine damage...
