Straight piped - uh no

[svtnos]

So i jumped on the band wagon of cutting the muffler off and kind of going straight piped.. the cat is still there and is staying there.. what i found out was this dumb lil 4cyl is absolutely stupid loud and is no way tolerable for my daily commute.. so when i got back home i welded the muffler on.. i started thinking how so many people could do this and not go def.. now i realize that most who do this , they have the turbo.. i do not... i cant believe the turbo quiets the exhaust that much to make it tolerable.. that is just crazy to me..

i was at tractor supply the other day and thought how funny would it be to replace the stock muffler with a muffler from a tractor.. lol i might have to try it..

Most tractor mufflers are built like a glass pack. It will quiet it a little, it will still make some noise. You will have to try it and see if it is too loud for your daily driver.

thrush cherry boomb all of them will some will knock the edge off of the sound maybe kind of give it more of a bassey sound I think Nitro has some thing like that on his PT

i did notice how they are straight through with some baffling .. that might be just enough to make the 3k drone a lil less..

in a non turbo PT i think all you want is a very slight increase in noise.

IMO all non turbo 4 bangers with automatic transmissions sound like "nope" which is what you have, no?

MY pt was quiet but sounded OK at WOT due to dumb luck... the pipe had a 12" x 1/8" split in the bend right before the muffler... made it sound pretty much perfect for what it was..

since you have a welder, you might fab something up so you can allow some noise to get by. i like making cable operated cut-outs with cheap old throttle bodies and salvaged bicycle cables. lol

that sounds pretty good.. but yea, open exhaust on a n/a 4cyl is a big nope.. i just want the lil guy to make a tad more noise, but not be obnoxious about it..

The turbo quiets things down a WHOLE lot.

Back in the day, loggers with turbocharged Cummins engines would run one straight pipe on their log trucks. And it wasn't that loud. But put straights on a supercharged Detroit Allison 8V71 or 8V92 and it would be so loud your ears would ring. The same was true for the old non-turbo 250 Cummins and 237 Maxidyne engines.

To me, the straight pipe on a turbo PT sounds kind of like a late-model John Deer tractor (which sounds good), but it's not super loud like the NA would be.

PS: One of the things that disappointed me when I started messing with these little toy-sized turbocharged PT's is that the turbos don't whistle. On big trucks, the turbo would get to whistling like a jet engine went under heavy load or when the fuel was turned up really high. On the Cat engines, the engine itself got quieter under load so eventually all you could hear was the turbo whistling. It sounded and felt like you had a jet engine under the hood.

..back in the day....... us Hot Rodders and Drag Racers liked the sound of the a 671 Blower in a Camaro or Mustang,etc., or the sound of a Pet Jackson Gear drive on any V8 engine. Turbo Chargers always sounded like the engine was leaking something.

Even my 2 MINIS the better sounding one if the Super Charged MCS not the Turbo Charged engine. I even filled the BLOWER on the MINI so it was much louder.

WOW! Pete Jackson Gear drive, I haven't thought about those since eighty-something. I'm with NitroPT on the blower vs turbo thing. A big ole polished 671 with a pair of Holleys beat a whiney turbo any day in my book! If I remember right, Buddy Ingersoll ran a turbo V6 Buick in Pro Stock for a while and that brought attention to turbo charging.
