Amazing the difference a day makes


Good for you.  I know what you mean about that blaaaap sound. It can drive you nuts. My freinds 350 powered S10 is doing just that  and he hates it. Did not do it when he had the pipes dumping behind the cab. But when he put on tail pipes to the back, thats when it started. I wonder if cross over pipes might work for him ? Did you put the cross over pipes before the mufflers or after the mufflers ?

The crossover pipe is connected where the downpipes do a 90 degree turn underneath the ram horns, a few inches towards the back.  Its threading the tiny gap between the front crossmember  and oil pan.  On an S-10, there should be more room than on an X-frame.  And from what I've read, it should go before the mufflers.

Just picked up the '63 from the muffler shop last night.  I had a pretty hood style glasspack system dumping in front of the rear tires.  Way loud and super droney, not to mention a little stinky inside the car.  So I got the guy to fab up a crossover pipe, and custom bend new tail pipes over the axle and straight out the rear.   All I can say is wow!  Its like night and day.  The crossover kills all the resonance and quiets the blaaaaaaap down to an awesome rumble.  I wish I recorded before and after audio.  You wouldn't believe the difference.   

Funnily enough, I was initially thinking of adding small resonators at the back to tone down the glasspacks, but I'm so glad I didn't.  I don't want this thing to be purring like a prius!

Michael, can you take some pictures of how it fits with an X frame? Thanks.

for sure!  Sadly it was off the hoist when I picked it up so I'll have to jack it up to snap some pics.  Stay tuned!

Now my next dilemma is what to do for rear bezels?  Do I dare chop up some unobtainium reverse light housings, or try and make something that'll tighten up the gap.

Thanks for the pictures.

I would fab something. '64 reverse lights are different. You might be able to find some '63 delete plates to use like my '64 one pictured below.

The Crossover pipe looks awesome but I would be concerned about the extra heat in the oil, I would be interested in making a heat shield to keep the oil temps down. Just my opinion, but I really like the crossover pipe and will definitely entertain that idea when I do my exhaust.

Good call on the extra heat. I'm gonna have to wrap that pipe in header tape. And maybe pick up that aluminium finned pan that I've been eyeballing. Thanks

Very interesting installation!  I've seen a few cross over installations over the years,..(not on 64's) ... but I've never see one in that location.  They were always much further back,... near the transmission pan area.  I would imagine on the old full X frame,... that was the only place to put them.  65 and later were uni-body,... so the crossover could be installed more conveniently further back.

 Where did your mufflers end up on this install?  I am doing the exact same thing and the installer wants to go with 18" magna flows but said it had to stay under front floor pans because no room in back

I've got short glasspacks in the stock location, so yeah, under the front floor pans is where I run them. I was thinking about removing the glasspacks and putting resonator style mufflers between the rear axle and bumper exits, but I really like how it sounds. Why mess with perfection ;)

I really like the way you've got them exiting the bumper machine gun style. As far as a bezel, there must be something somewhere that could be repurposed for the job.

I'd just start snooping around home depot, wallmart or even a kitchen fixtures or lighting store. You never know what you might find that could be adapted. Cheers.

C2 Corvette bezels might work, not sure on the angle.

I think that front crossover was where the it was on a single exhaust x frame V8, the 283's. Here's a pic from the web:

I had straight pipes with resonators only on my 59 283, duals out the back by the bumper. Didn't sound bad at all inside the car. I added some turbo mufflers and exited out in front of the back tires, quite loud inside the car, I assume since the noise came out by your left ear instead of behind the car. But my neighbor found the pipes with resonators only out the back much louder.Duals with no crossover in both cases.

 Thanks man, much appreciated, yours looks pretty trick as well.

Oh and in regards to the point someone made about the H pipe running across the oil pan, thats exactly how the original single exhaust was routed with the cross over in the exact same position.  With that said Im going to throw some heat wrap on too.

 

Cheers
