exhaust

[nytronympho]

Does anybody know if it hurts the motor to run it while you have the muffler or pipe off -- just like a straight pipe-- I had heard that its not good for the motor any truth to this????

No back pressure = No good

 

[snefokk]

the 2stroke needs back pressure,but the 4stroke....i dont think soooo...

 

[horkn]

It won't hurt it....

 

[foe]

Might hurt your ears.

i took out this from my stock muffler,so the exhaust is almost going straight trough, and i got a much better sound too

 

[legends14x]

What exactly is that and how did you remove it????

 

[sleddingfarmer]

so we've decided its not gonna be bad for the motor? Cause I'd probably be interested in doing that...was it difficult?

 

[snefokk]

this is the pipe that you see when you look inside the muffler from behind,sort of.
I cutted it in 2 about 1inch from the backside,cut this of and welded it back together,took me maybe 30 minits or so, i shall try to draw what the exhaust looks like

 

[snefokk]

here it is
start to look at the bottom drawings and up.

this is a pic that someone posted earlier in the year,sorry i cant remember your name but i thanked you before on this issue,your pic showed me where i was to make my attack on the quiet problem,the right side top is the "in" side and the bottom left is the "out" side

how loud did it get? I like this idea more than putting a aftermarket exhaust on there, will look completely stock so i can't get a stupid ticket. I just want it to be a little louder, as loud as my friends 06 attak would be great

 

[snefokk]

it got a little louder ,maybe like the 06 attack,difficult to say, i can try to take a sound test
i can drive here without the muffler if i want to, we dont get a ticket because of the sound or looks....

I bought a muffler from a 08 nytro and it wasnt welded inside,just had to pull it off when i had it cutted in 2, so now i have the stock IF my wife think its too loud to replace it with, and it was MUCH cheaper than buying an aftermaked muffler

You could always drill holes in that pipe instead of removing it, that would be less noise, but a tad more than stock.
