Is aftermarket S-flow muffler any good?

[Veloc]

Dear forumers,

Just something I want to ask here. Most cars comes with s flow exhaust stock. Most people who want to upgrade will change to a straight flow.

But there are aftermarket mufflers that are S-flow as well made by performance brands such as FGK S flow 2.3", Tanabe G power S flow, TRD S flow and so on... I want to ask is there any difference if we change to these aftermarket s flow muffler or is it just for style only? Because it is still s flow and not free flowing.

Anyone got experience?

The reason for S-flow exhaust is for sound deadening. Aftermarket S-flow offers better flow that stock but is still quiet, although not as quiet as OEM.

Yes I am asking in terms of performance. Since it is s flow, I think that the flow is still restricted (correct me if im wrong), so what is the use of it?

Like I said, better flow than OEM, and usually weighs lighter too. So ----> Straight Flow> S-Flow> OEM

weight lighter? hurm.. but why my supermegaphone sflow more heavy than my stock exhaust?

Want performance but in the same time not hurting ur ears, choose straight flow but with big barrel like l've attached..l've tried s-flow and my conclusion, it couldnt satisfy my expectation..quiet, yes but performance, need to step ur pedal even more to make the car moving

Sorry, when I said lighter I was referring to the general aftermarket exhaust piping, not just muffler. Muffler weight should be more or less the same...sorry2..
Performance wise, just changing your exhaust is not gonna yield much power difference, be it straight flow or not. Extractors, for example affects performance more than the exhaust.

agreed with you.. stock exhaust more pikap than s-flow even with aftermarket extractor.. erm..

 

[DanzEterna]

im also using s-flow hks super dragger. so far ok je.

 

[aHLengChai]

maybe cuz waja stock extractor 4-1.. so when switch to 4-2-1.. tu yang terasa heavy than stock..

some says s-flow is only meant for auto cars and big cc cars...some says s-flow is for top speed performance whereas straight flow is for pickup..some says 4-2-1 only can mated with straight flow and 4-1 suits with s-flow...haih...bla..bla...bla...too many formula to list down...for me, NA user, an aftermarket 4-2-1 with straight flow suits me...a bit of rempit and abit of cruising...happy modding

The reason I ask because I want something that increase performance. Headers is out of the question due to budget and time. When going fr a major overhaul, then I consider doing the headers as well. Now just looking for a fast and cheap option. I wanted straight flow but am traumatised by the noise as I was using straight flow last time. So I considered aftermarket S flow but then am not sure whether it improves performance or not. That's why I ask.

But seeing you guys said that aftermarket s flow gives very little gains, I think I must look for some quiet yet powerful straight flow. Thinking of HKS Silent or Tanabe Touring.

Bro,u r running on auto or manual? My 1.5 sohc auto's pick up did improved with a twin loop s flow exhaust.. :)

No manual bro.

Last time auto with straight flow. SUCKS. So I changed to stock s flow then okay.
Then later on I changed to manual tranny. So now it is manual with s flow. SUCKS AGAIN.
