1981 XJ750 Drag Bike Potential Exhaust Fitment Question (Bike is built already, not a daydream)

Image Below

Alright gents, i wouldnt normally ask something as simple as a fitment question, but as this bike is very different than your standard seca i figured id ask.

Like the title says, its a 81 750 Seca. its a wheelie bar bike. I know ill be asked so these are the current stats i have down, the previous owner put work in at a performance bike shop/machine shop (wasnt clear). They built this one off engine.

~14:1 compression is what I was told
Mikuni vm29 smoothbore carburators off of a KZ1000 I believe
Triple valve spring set up with titanium retainers
Unknown cams .480 lift is what i found
4-1 Exhaust rusted to nothing from sitting.

So i want a 4 into 2 exhaust to get the bike as low as possible.

This is my option, comes in black and chrome http://www.nichecycle.com/ncs/categ...-4-2-w-megaphones-blk-by-mac-performance.html

Im just not a fan of the way it looks, if its the last resort, its what i will go with.

Here is the question, Would a xj650 maxium exhaust fit with a bit of love. Im really into how the exhaust turns out. The louder you can be towards the other person, the more it gets them off their game. Here is the exhaust

there is a company out there that sells exhaust components to make your own exhaust. why not just stright pipes? and put flares on the ends pointing out.

You haven't said what you're doing with it? Will you be dragging it? If so you want a decent bore 4 into 1 surely?
Oops, rechecked, yes you did. Answer is the same though 4 into 1. No silencer, staight pipe with an abrubt end, about a foot and a half from the collector.

 

@Minimutly the collector of a 4 into 1 is pretty tall under the bike, thats what it had. At full throttle pretty much all the time, im not too worried about exhaust scavenging.

@XJ550H i could go that route, but it may be a little out of my skill set as my welding skills arnt very good, but hey i could practice doing this

Thomas,
Here's a MAC 4 into 2 exhaust that I made a video on and still have it sitting in my shed:



Might be something you can work with, and for the cost of standard shipping it's yours......

Start a conversation with me if interested.
