After getting twin Kads ive been told that the stock exhaust is till holding it back a little.

With extractors is it possible to retain the stock looks ie twin tails

I love the stock look anyone know of any solutions?

That Aircooled muffler would be the eaier alternative, but if you're gong extractors, you might as well get the better flow ALL the way through the system ay? Where the headers merge into the muffler would create a lot of turbulance IMO. The CSP solution would be much better.. $$$ though... good luck

I am running a 1916 with stock rejetted carb

It is a Peter Shelley motor.

50 ponies at the wheels.
bout the same as i would expect from a 1600 with twins

My 1776 with webers did 60 at the wheels


The exhaust have was/is a bit of an experiment.
No way am i spending $2k on an exhaust.

I agree - they look silly if you dont have pipes coming out the cutouts.
When i have reason to change mine i will rethink the answer.

What difference have you noticed with the Kads??

Any?? (hopefully yes)

You'll lose some ground clearence i think... anythings possible though, just be prepared to have lots of trial and error if you're doing it yourself. I had a similar experience lately... very drawn out affair...worth it in the end though!

yes

you would cut it between the flange and the muffler

the muffler then sits sort of up under the guard (ish) and pipe welded between.

after the leaving side of the muffler it is extended back down and T'd to exit both the stock holes.

Someone handy with a welder would knock it up in a day - otherwise a days labour at Speedy Mufflers ...... $500??

I would put the header on first and see if there is a noticable enough power increase to warrant the stuffing round.

No point doing the $$$ and then finding out there was no noticeable power gain

thanx Baz, not sure if I want to spend $500 on a exhaust system.

but as u said bolt the other on see what gains can be had and then decide

I should also get in touch with Speedster Pete he may be able to help me with something😎

i think thats hows Daves oval was done,using an old muffler to cut and weld into place to give the effect off the stock look with the pipe dumping out beside it at the end 🙂
