Who makes after market exhaust for a 20hp go devil LT with vanguard motor? Do y'all think it will run well on my 14'40"?

It should do OK on your 1440, never gunna be a ball of fire.

You may need to check around. I think the 20 block is the same as a 23 They make em for 23's

interested in what responses you get, im looking to do some upgrades to my new to me 20 hp GDLT..it doesn't haul ass by any means

The 20 and 23 blocks are NOT the same!

I had to replace the motor on my 20 LT (sunk in Katrina) with a 23.
Everything bolted right up EXCEPT the muffler! There ain't much difference but the 20 muffler will not fit!

If you can use a stock 20 muffler, I just happen to have one with one season (fresh water) I can let ya have for less than 1/2 the price of a new one , say $50.00 and you pay the shipping.

I had my 20 LT on a 14 / 40 flat when I first got it. Performed OK.

On Coco's advice, I switched to a 16/36 boat and picked up about 4 MPH even though the 16' is fiberglass and weighs about 250 Lbs. more that the alumimum.

Long tails do better on a longer boat. But, run what ya got, it will be OK

Just my $0.02

Thanks for the help. I am looking into a 1644 GD boat to put this motor on now. should be a better fit from what i've read.
