High Flow Muffler Or Cannon

[debmatt09]

Hey guys

I got supercat cannon on my R33 Series 2 rb25det,

Its so loud sometimes even on the highway and Im hearing impaired too still loud for me!

Im running 3inch from turbo with hotdog to cannon

Whats best way should i do? proper cannon? highflow muffler?

I just get too much attention with the exhaust so loud

Ive looked on google too seems not the right answer for me

Thanks

Matt

Yeah basically the centre muffler is the main one for loudness while the muffler out the back more controls the note, ie: cannons tend to drone where as mufflers muffle (funnily enough)

That config will bring you to around 87-90dB in most cases in 3".

Gotta be straight through for best performance and also as big as possible.

So basically the smaller you go from the "biggest possible", the louder things will get.

Either way a hotdog + cannon is doing you no favours. You might find just a single rear muffler might fix your issue.

Everyone is different when it comes to "how loud" something is so i just refer it back to "legal" which is 89dB in Vic in terms of a point of reference.

If you want quiet without the excess noise look for something stamped JASMA

I had a 3.5 inch exhaust on my car with no mid muffler and a JASMA rear muffler it was sooo quiet I had to change it you could barley tell the car was on, it weighed a ton though

i just have a single 3" muffler on the back of my rb26.. sooo quiet its ridiculous, they call it a centre to centre muffler (regarding the IN/OUT positions). the path is straight thru which i guess is good for maintaining performance. any exhaust shop will stock the one i have, then just put a nice shiny tip on the end, and your flying incognito again.

ditched the cannon a while ago, but will be returning to it with no cat for WTAC only
