What makes an exhaust POP>?

[Harry_manback]

mine pops and bangs like a mofo. 172, Ktec stealth, 182 manifold, de-cat.... oh and bodies, cams, pistons etc etc.

Goes off like a shot gun on full throttle gear changes too!

i think i hear it popping on full rev changes, but its abit loud when thats happening so i cant be sure.

the yz exhausts i've heard sounds like they wanna pop all the time whereas mine just sounds like a angry old man talking under his breath.

maybe it is in your 4-1 172 manifold.

Things happen differently when you actually fit your 182 manifold.......


:rasp:

:quiet:

Newbie question...

Can you fit a 182 manifold onto a 172, are they different? Any gains etc?

Answer Yes. Gains are small but noticable and well worth it if you are able to do the work yourself.

F4r lumps dont pop as standard. The 182/172 pop a little on idle, but unless running cams/bodeies wont pop

 

[sideways danny]

it's much more to do with ignition timing TBH

 

[willcrook]

fm that rx7 sounds like a machine gun,

I think that purposely wanting your exhaust to pop is abit gay

Is that with blueflame? Mine used to do that.

Yeh blueflame. Theres no centre box on blueflames so its straightthrough all the way to the backboxes. Only pops for the first 5 mins after start up though. When revving.

My blueflame pops with just the cat back system!
