I don’t know. I’ve heard from a few people who say when you open up the exhaust on these small 4 bangers weird stuff happens.
My engine was perfect. Like mint. Put it in, basically have an open exhaust with a header then I had a weird issue that was solved by moving the distributor a bit.
Maybe not a myth?

These have caught my eye. 10” long on the Toyota one. But the 6” around might be hard to package.
I have had good luck with spin tech mufflers, I’ve put them on lots of crawlers where clearance is tight. That being said I’ve never put one in a Suzuki 4 cylinder.
This is there smallest option but has baffles rather then straight through like most small non-offset mufflers.

funny story.. and dont laugh. put the question into chat gbt. something like this... i want to take out the drone and and quiet down my off road buggy runny a 1.6 l open header blah blah no cab just roll cage and sheet metal. it so loud we cant talk back in forth at 2500 rpm but can talk at 750.
anyway word it something like that. and see what chat will spit out. i did that this fall for my buggy and it recommended a resonator 18 inches ahead of the the muffler. and holly chit its super nice now.
what was nice is you tell it how much room you have. for me under the seat i had 15 inches by 5 inches and it sourced a res to fit that dimensions.

The 8v's like a bit of back pressure until about 5500rmp. The pulling header made less torque off idle, but felt way better in the top end.
Vote for the quietest muffler you can find.

Wanting to put a small muffler like you are looking for on my krx. Trying to learn from the tech.

I'm rocking this sweet "muffler" from Pypes:
www.summitracing.com
It's a 2.5" inlet/outlet, 14" long and 4" around.
It does almost nothing.
I already have a certain amount of hearing damage and would like to minimize adding to it.
Is there any small stainless mufflers that actually do something? Is there any that are round/straight through sized, but actually are baffled/chambered? It can be fairly restrictive and it won't matter. Getting it to fit is the main issue.

I went to my local auto store and made them find me the smallest stuff they had. Ordered a Walker cat that’s 5” long off Rock Auto.
Will post pics when everything is done.

While waiting on my Walker cat to show up, been cleaning up the SD60. Decided I don’t want to be broke for a hobby I only do 3-4 times a year. So cheaping out again.

What does cheaping out again mean exactly?

Back pressure is no myth. Welded this all up, fired it up, and moved my distributor back to the original location before I pulled it (mark was still there 
). Problem solved and this is going to run ten times better.
Walker cat some Xxelerator turbo muffler.
Time for ceramic coat.

Have you checked to see if your EGR valve is stuck open?Back pressure is no myth. Welded this all up, fired it up, and moved my distributor back to the original location before I pulled it (mark was still there

Backpressure should not cause your conditions, it can change tuning though and maybe the carb can't compensate for some reason.
Glad its running correctly now either way.

Yeah man, I replaced and cleaned everything, tested everything, it’s all like 40 pages back. Back pressure definitely messed with the ECU tuning this motor.
It sounds exactly like it did when I originally pulled it now.
What are you referring to?

For the front axle.

Currently IFS Toyota hubs with keyed Front Range Arms.
I don’t want to discuss my future build here. So, when/if it gets done I’ll post completion pics and details.

Well, got a cheap 2004 Sebring pulley in. Garbage machining on these new products. Had to sand down the inside.
Pulley is also plastic.
Belt is 37”.
Hey FleshEater is this serpentine water pump pulley a stock 1.6L 8V part?

Yes, my water pump is factory. The power steering pulley is from something else.
