i know this post is for an 89 but i figure it pertains any year. so i was changing my oil pan gasket today and i had to take off the down pipe to remove the pan so i thought i would go the easy way and only take off the down pipe. when i tried to take it off one of the nuts and the bolt threads stripped out so i just took off the entire manifold. but when i went to put it back on one of the other ones stripped out and now im left with one almost stripped that is holding it on not very tight. this just became my reason to spend all that money on an upgrade since i had the stock manifold and down pipe. right now it sounds almost like a air hose when i accelerate. i was just curious if i will do any damage to anything driving around with the gap between the header and downpipe.

thanks

Except for some noise and a stink, no it won't damage anything but your wallet when you get excessive noise tickets. Use this as an excuse to get a new header

 

You will loose some back pressure, which will in turn cut your MPG. My muffler was hangin and mine when it the shitter

 

They make 89 si headers?

 

I would be concerned with that exhaust gas making its way back into the engine, through the air cleaner which cant filter carbon monoxide, the carbon monoxide can build up inside your engine.

 

but for a week or two maybe driving a total of 600 miles shouldnt hurt it too bad until i get the header....and yes im pretty sure they make a HEADER for 89si...other wise im sol

 

I...just...wow..........wow

 

Are you kidding?

Honda has been using the same motors since forever .

Exhaust leaks are bad, aside from the fact that you could go unconcious randomly when driving long distances... ( :reechy: ) itll deafen you.


You shouldn't really do any damage, EXCEPT the fact your putting more strain on the surrounding studs/nuts , which could lead to more issues.

 

how do you explain that i drove from columbia to kansas city and back and then some (371 miles) on one tank and when i filled up after that tank i couldnt fit 10 gallons in so that tells me that i probably had about a gallon left which would have put over 40mpgs. so much for the back pressure myth
