Installing Exhaust?

[bluebaron]

I just got a used sparks exhaust. I'm having a few problems. The first is, where the header slips into the mid pipe from the silencer. It is not fitting tight, it's noticeably loss. And the other problem is I cannot get the header tight with the engine. Is there a crush washer that goes in there? What can I do?

There is a crush gasket where it bolts to the head. There is also a gasket where the silencer slips on. You either need the silencer gasket of you received a silencer for a full system and need a head pipe. I'm not familiar with the Sparks system so I can't be sure. Good Luck!!

Where can I get a crush gasket? are they all the same or, exhaust brand specific?

From Honda.

They are the same.

The Sparks has no gasket or anything where the header slides into the mid pipe.
Doesn't even use a hose clamp.

most just use a bead of high temp silicone (copper stuff) at mid pipe

and you need a crush gasket and you may want to double nut the head pipe (they like to vibrate loose)

Alright I have a new crush gasket on the way, and i'll have to see if some high temp silicon will work, although its pretty loose. Thanks for the help guys.
