will a cannon give me the suby rumble?

I know there is plenty of threads on this subject but bare with me. Today i was looking under my brumby when i realised it actually has a 2 inch pipe after the headers, down to just before the rear muffler when it goes down to about 1.75 inch with a long hotdog. I was wondering if I put a cannon on the end of the 2 inch pipe will it make it sound like a wrx?

Makes it sound awesome as most boxers do but yeah not quite like a rex in my opinion.

I'd stay with 2" all the way, straight through with 2" tip, sound nicer than a canon imho. when you take it for a rego check the mechanic won't laugh behind your back at your canon either... each to their own though.

Not exactly like a rex but most people that don't know much about subies won't be able to tell the difference.

I got it done to mine from a place called Streamline Exhaust (mainly because I didn't have a welder etc etc).

I got a 2" straight pipe to the back (No catalytic converter, EPA laws are almost non existent in SA) with a stainless steel cannon for $180 installed.

Worth every penny, the car sounds mean now.

well I don't mean specifically like a wrx, just that nice suby rumble that you hear on foresters, wrx, liberty etc. I understand it will sound a bit different due to the different engine.

so if I get rid of the 1.75 inch pipe and oval muffler at the back and replace it with 2 inch pipe and a cannon it will sound a lot better?

You could put a 3" oval, straight through muffler on in place of the cannon and get similar results, without the wankyness of a cannon.

Remember that the shorter the tailpipe after the muffler, the deeper the note

Don't I know this I took the end of the muffler off on a wash out out bush and it sounded awesome The biggest problem was It didn't have the power to back it up!

my brumby has what you mentioned with a 2 inch pipe but has a 1.75 inch pipe just before the rear muffler and what i'm guessing is a stock oval muffler. Which is better in terms or performance, sound and cost, a 5 inch cannon tip or a straight through/high flow muffler?
thanks

Tip ftw. It's gotta be chrome though.

does the size of the cannon make any difference? for example the bigger the louder etc?

Gannon · Post by **Gannon** » Tue Aug 11, 2009 5:56 pm

Usually the bigger, the deeper the sound

bigger cannon and pipe that it is attached to the louder the noise.
e.g. i run a 3" system on my rex including dump pipe with a 4" oval muffler and its pretty loud so i am told. and its a top quality Butler exhaust system, not cheap
If i changed it from the diff back and bolted on a 2.5" pipe with a 3" oval muffler it would be quieter, maybe little power loss.
But with an N/A car power really doesnt come into play with exhaust.
I had a cannon on my old L series from diff back, embarrasingly loud, was about 4"
would never do again imo.
muffler ftw!

i gotta 3.5" cannon on the back of my lib, but still dont have that nice rexy sound.. gotta 2" stock running straight thru to the cannon... any tips?:???:

I've got an ea82 with a 2 1/4 inch exhaust with a hotdog and i've had both a 3 1/2 cannon and a high flow muffler.
With the cannon it sounded hell tough doing 60 in fifth and was really great fun when when you nail it, but i like that sort of thing, now i'm using the muffler to stay legal.
Imo, yes it does, but it's all taste

A cannon with a 3 inch outlet and a 4 inch overall diameter, will be louder than one with a 3 inch outlet and a 5 inch overall diameter. Due to more area for sound deadening

Hope i've been of some help

I've heard that a 2 an a quater inch cat back system is the go, it should do the job for you.

A 2" straight thru system with a normal shaped but straight thru muffler sounds a treat in my opinion.

Example of that setup on an EJ22 Brumby
