H-Pipe crosses where? '65 convertible

760 Views 6 Replies 4 Participants Last post by  Jay
Last night I started figuring out how to get my exhaust out of the engine bay and under the car. I've got reducers which bolt onto the longtube headers. I bought an H-Pipe kit some time ago that consists of two T shaped pipes and a crossover. My question is, where should the crossover be related to the C4 transmission?



p.s. I mean front to back. Obviously it goes underneath the transmission /forums/images/icons/wink.gif

the crossover is usually near the tailshaft of the transmission

I concur with Mr. turner. My H-pipe is under the tailshaft of the transmission, just aft of the crossmember.

Get that motor running yet?

isn't there a right and a wrong way to install your crossover tube? i've been told that to do this correctly, you have to get yourself a grease pen or crayon. draw a line after the collector. run your car hard around the block. note where the discoloring or burning mark is and that should be where your h-pipe should be installed.

Through I guess. That's where they are now. I cut the exhaust last night just in front of the convertible floor brace. If I can get it to the H-pipe, that'll have to do until I can drive it to the muffler shop.

And to answer Steve's question. "No" I've got to line up some help to get the engine back in. It doesn't look like a one man job to me.

When you get it back from the Muffler shot get some pics up please. I'm going to be taking mine to a shop in the near future to have some nice header to muffler pipes made with an H crossover. I'm ditching my X-Pipe setup, it's leaking all over the place and was a VERY difficult fit on the 'vert.
