Straight pipe exhaust from the converter(VERY LOUD)

That's supplied by the turbo pop-off valve...

 

BOV (Blow off Valve)

Someone like my postings so i can start my own thread. I got lots to share

 

BOV on a prius? At least on that one?? No way..not a chance - not at a real BOV.

 

interesting read there. always wanted a supercharger... but stickin up out of the hood over a hemi or a 427.

 

I have just one question? Why?

 

why not?

 

Because it is loud and upsets people.

 

well if they get upset you can call a waaaaaaambulance...
no matter what you do to a prius, it will never be as loud as the drag pipes on my shovelhead. I like it when it sets off car alarms.

 

Loud exhaust ??? Name your car The Ticket Taker .... The boys in blue love noise

 

I guess it depends on where you live. never had a noise ticket except once in 1979 after the muffler on my 1st Chevelle fell off.

 

Interesting! It sounds nicer than I expected it would, and at least from the videos, it doesn't seem as loud as I anticipated. I think my '85 Toyota 4wd with a mostly-intact exhaust system (with a few rust holes) is louder. I don't imagine your sound level would attract too much negative attention...a lot of the cars on the road around here are probably louder and do have mufflers. And it's probably a few orders of magnitude quieter than some of the choppers...

 

a few orders of magnitude quieter at WOT than my chopper at idle...
I must confess I had to put baffles in the drag pipes. it was so loud with open pipes at highway speeds it made my whole head ring, painfully loud.

 

As they say, ignorance is bliss.

 

no it wasn't. that's why I needed baffles.
