MIKEYFTW Posted September 25, 2023 Author Report Share Posted September 25, 2023 Anybody know where I can source a Y down pipe for after the exhaust manifold. This leaky exhaust has been fixed multiple times… always spits the nut off the bolt. The Y pipe isn’t sitting correctly causing leaks. I need a new down pipe and was wondering if I can get anything new? Will those d21 headers fit on a ka swapped 620? Quote Link to comment
datzenmike Posted September 26, 2023 Report Share Posted September 26, 2023 That's asking a lot. 620 with 3rd generation engine swap down pipe to clear the torsion bars. The good news is the transmissions are almost identical physically so it will clear that. 1 Quote Link to comment
Dusten Posted September 26, 2023 Report Share Posted September 26, 2023 Buy a flange off a guy on FB. Have an exhaust shop fab up the pipe. That's what I did. 1 Quote Link to comment

Thanks that’s exactly what I needed. I will try emailing him. I don’t have Facebook access, I tried logging back on and it never let me. I’m missing out on a lot of Facebook marketplace deals.

Just PayPal’d him and he already had what I was looking for and is on the way to post office. I’m excited to finally have my truck exhaust leak free I might go all out and add a cheap aftermarket cat just to finally get rid of all the exhaust smells I’ve grown use to. Thanks Dusten 1 Quote Link to comment
datzenmike Posted September 26, 2023 Report Share Posted September 26, 2023 A cat won't get rid of smells which are exhaust pipe or gasket leaks. Make sure the system is air tight and the pipe exit is at least behind the rear axle, preferably the rear bumper. Be sure block vent hose is connected to the PCV valve and the valve cover vent hose to the air filter or engine fumes will escape into the engine compartment and from there into the cab. 1 Quote Link to comment

I’m planning on cleaning engine Bay Area and refreshing all the hoses I can. Gonna bump this thread up with more pics. It’s fun looking back on this project and seeing pics of when I just got it.

FrankRizzo Posted September 27, 2023 Report Share Posted September 27, 2023 I put a hi flow cat converter on my KA24DE. Since it was de-smogged it really stunk and I had the AFR tuned in perfectly with the Megasquirt ECU on the computer, so it was not running rich. My wife would not ride in it. It's probably 70% better now smell wise (and I dont get hose nasty looks from other drivers. I honestly cant tell any difference in performance or sound either.... It was not cheap, but it sure helped in my case - it was a lot cheaper when I bought in in 2022 https://www.summitracing.com/parts/WLK-81802 2 Quote Link to comment
MIKEYFTW Posted October 4, 2023 Author Report Share Posted October 4, 2023 (edited) Trip report with the Datsun Chinook. Listen to that exhaust leak! Put the chinook away after this trip to fix the exhaust leak. https://youtu.be/cWiJ5DrPsMM?si=cuIVMvKUia22vFfO Edited October 4, 2023 by MIKEYFTW 2 Quote Link to comment
