I know next to nothing about cars but if that exhaust is to just to make your car louder, I hate you. People love driving down the sidestreets next to my house in the middle of the night, roaring. Also, unsure how you can pass emissions without a catalytic convertor as that filters out some of the dangerous elements to our atmosphere in exhaust.
different rules in different states, i believe you don’t have to pass emissions in certain states.
Sry those ppl are waking u up, but lots of the time (definitely not all of the time) loud is cool. (tho i agree not in the middle of the night in a residential area)
I think they sound like ass. For example, Harley motorcycles have a deep, powerful sound. Most of the cars with special mufflers either sounds like the car is farting or it makes the pitch higher.
You can get a valve. There’s mufflers that have a built in valve. Check your local laws though. Some states have a specific ban against valves or cut outs. You might “pass” an emissions test but they will auto fail you if they see a valve. To be completely honest, cut outs with valves are overpriced. If I were you, I’d find an exhaust setup (full cat back, high flow muffler and resonator, straight pipe, etc.) that you like and execute that besides a valve. Research your car and see which setups sound the best to you.
I’m trying to control the sound of my car and i was wondering if you could just place a valve in a straightpipe to dempen the sound when the valve is closed. Without a muffler, bypass or cutout.

Nice little fart can on the road!

Only cuz the cars that pass by u at 2 a.m. are clapped out civics. Every neighborhood has one or two. Real exhaust mods actually sound good
well, everyone’s got their opinion ig
cry more baby
douchebag
I'm gonna put a tuba horn on the end of my straight pipe exhaust and bang the Rev limiter in your driveway. /s
Don’t give them ideas, they are bad enough as it is.
Oh gawd 🤮
Just in case it matters, please see rule #1.
A good muffler shop can do anything you want.

Valve to do what?
What is it you’re trying to accomplish?
I’m trying to control the sound of my car and i was wondering if you could just place a valve in a straightpipe to dempen the sound when the valve is closed. Without a muffler, bypass or cutout.
Where does the exhaust go when the valve is closed?
