Didn't mean the carburetor screws, that would be more for idle. More the jets to correct any lean or rich. Quote Link to comment

I new about adjusting the jets but ill call a couple shops and see if I can get a borderline price of a tune. Quote Link to comment
datzenmike Posted November 21, 2021 Report Share Posted November 21, 2021 I doubt you will notice much. I'm talking going from a stock exhaust system to open header. It can sometimes lose low speed power but gain top. If you have a pipe and the low restriction turbo muffler it won't bother it much. Quote Link to comment
JacobBieg Posted November 22, 2021 Report Share Posted November 22, 2021 Ok that might be the plan, I was planning on running the pipe all the way to the back of the car and using a pipe adapter in order to but a nicer tip on the exhaust to give it a little more shine. Quote Link to comment
JacobBieg Posted November 22, 2021 Report Share Posted November 22, 2021 So if you think a cheapish turbo muffler would get rid of some of the possible obnoxious popping ill look into purchasing one Quote Link to comment
datzenmike Posted November 22, 2021 Report Share Posted November 22, 2021 I would look for something you can't see end to end through. Quote Link to comment
JacobBieg Posted November 22, 2021 Report Share Posted November 22, 2021 ok got it, Thanks Quote Link to comment
Aaron Datsun Posted February 13, 2022 Report Share Posted February 13, 2022 Here is my contribution. I decided to run a 2" exhaust off of the stock exhaust manifold. With a 2" muffler on the back. We're I to do it again I would have found stainless steel, as this mild steel immediately flash rusted and I am worried that it won't last a super long time, but I like the way it sounds and is tucked under the car. The only thing that didn't get completed was the retainer that keeps it from rattling on the rear cross member, so that happens from time to time. https://youtu.be/SqxYQ4q5Yok 1 Quote Link to comment
banzai510(hainz) Posted February 14, 2022 Report Share Posted February 14, 2022 (edited) My first 510 still has the mild steel 1.75 inc exhaust I had put on. its still fine. since the 1990s. My 521 has aluminized pipe which I would use. and still looks GREAT. Aluminized pipe is Great on a budget and last a good amount of time. More than the vehicle now as most 510s get smashed now before they wear out Your overly worrying about NOTHING Edited February 14, 2022 by banzai510(hainz) 1 Quote Link to comment
mklotz70 Posted December 10, 2022 Report Share Posted December 10, 2022 I couldn't really find a better place to share this. I will no longer be making the downpipe flanges for the 4 cylinder L-series exhaust. I figured I'd share the CAD files on grabcad and I put a page up on my site. http://www.bluehandsinc.com/l16-exhaust-flange.html I actually still have a bunch of the 6cyl ones. I spent over $300 having them made and I've only ever sold one. 😞 I think the holes might be off just a hair. I've never had a way to verify them on a manifold so I really don't know. I'm tired of the box sitting on the shelf taking up space. If someone reading this has a 6cyl exhaust manifold to test one one, please msg me. 1 Quote Link to comment
datzenmike Posted December 10, 2022 Report Share Posted December 10, 2022 I'll say that Mike's flange worked perfectly on my home made down pipe. Looks good too. 1 Quote Link to comment

musichoard Posted January 4, 2023 Report Share Posted January 4, 2023 Here's my contribution. Took everything from this thread so far and kept everything at 2". Welded on a flowmaster cat, Thrush turbo, and even a custom mount I'm pretty proud of. DEQ has my CO at 5x the allowable limit and 2x the HC, so i'll be looking at the carb next, unless i've missed some glaringly obvious. the original exhaust didn't even have the cat Quote Link to comment
datzenmike Posted January 4, 2023 Report Share Posted January 4, 2023 Running rich I would think. Is the choke off when warmed up? Quote Link to comment
