Technical 49 mercury exhaust

Hey guys, looking for some good insight. I’ve been plugging away slowly at my 49 4 door. I’m quickly approaching the “it needs full exhaust” stage. The car has been lowered 4” in the rear and roughly 3” inches in the front with a set of Aerostar springs. I’ve got a set of lake pipes on it currently but have been planning to run it all the way out the back. I’m currently waiting on a set of reds headers to be delivered. However I need some insight. I plan to open up a few of the wholes in the stock cross bracing in the frame to keep the pipe tucked up higher, however I’m scratching my head on fuel tank clearance. The tank is offset to the drivers side of the car to compensate for the spare tire well. I still want the tank to be serviceable but I don’t want the tips to be pushed all the way to the outside of the body but I also need to ensure clearance with the ground with the car being lowered. Also entering splitting the pipes off to keep the lake pipes.

 

Wow, not much room under there, huh?

 

you make these oval holes on the other side.
Exhaust runs thru the frame
Make the tailpipes unbolt if worried about the tank

 

Connect the exhaust with these are something similar and you can service whatever all ya want

 

It’s not much, I can’t even get my floor jack under the car. I suppose the big thing I’m worried about is driveways. The lake pipes drag backing into the driveway here at the house

 

That was my plan, I do like the idea of the band clamps

 

Here's mine, front to back. Hope this helps.

 

Does it have a different sound or tone per side since the mufflers are in different places?

 

Not at all, or at least they're close enough that it isn't noticeable to me or anyone else. If one was waaaay back and the other was in front, sure, but these aren't that much different on a mellow Nailhead....I think the fact the tailpipes are close in length from the end of the mufflers matters a lot more than whatever is ahead of them....I've got an F100 that the driver's side is about 5 feet longer in length than the passenger side (both pipes have to run down the passenger side since the gas tank is on the driver's side, so the driver side leaves the header, crosses over to the passenger side, then down the passenger side, then crosses back over to the driver side for the exit), and on that there's some difference for sure, but it's loud enough nobody notices it but me when it's bouncing off of buildings.

 

When the cars were still fairly new, like '60s, we used 2 stock tailpipes. Cut crossmember holes to match stock side.
