I know this has been done to death and I know that the going opinion on this site is that the stock srx sliencer makes the best power. My question is this, on a lake race ported motor would an aftermarket silencer be better? I would assume that the object of porting is to increase flow, both intake and exhaust. An aftermarket can I would guess is more free flowing than the stock one. So I know on a stock motor stock can is the best but has anyone ever dynoed aftermarket cans on a ported motor to see if it helps? Also can anyone tell me what kind of can this is? It came on my srx when I got it and I have not seen another one like it anywhere and I've looked up all the aftermarket cans for the srx. Thanks.
 
The way I understand it is that althought the silencer may technically have more flow, it's design is not exactly suiting to the design of the pipe. So, although you technically have more flow, you are still losing horsepower do to the silencer and pipe trying to work against eachother slightly? Don't take it from me though... i'm far from a pipe design expert.

Hopefully somebody else will help chime in that knows more about this stuff. All I know is that more flow is not always a good thing... it is strictly the overall design and all aspects of the whole system that work with each other.

Anybody else wanna try? lol
 
SnowRules, I can tell you from first hand experience that a modded SRX700 motor does not like aftermarket silencers. I had a 98 SRX 700 with shaved piston skirts, porting, shaved heads, etc. I put on an MBRB silencer and I was topended by a polaris xc 700. Put the stock silencer back on and the power returned!
 
My 98 SRX 700, trail ported, V-force reed, mod air box,works fine with the Bender can!
I didn't lose hp anywhere, gained a bit in mid range but nothing on top end. the only reason one uses a can is to lose weight, if you are not concerned about weight than don't waste your money on a can. MBRB and other cans do lose hp on the top end.
I beleive that can in the pic is a DynoPort
 
dynoport has two different silencers, triple pack design and a single large canister. That is not a slp,mbrp,or hauck. I am 99% sure it is a dynoport...
