I was afraid you gona say that bigcry.gif

 

Do we consider muffler a wear and tear item, as in replace the plates/fibre every 3 yr? or replace the entire unit evry 5 yrs?

 

 

I didn't replace the Remus muffler even though it's getting louder as my Alfa was about due to be scrap in 1 yrs time, so during the last inspection, I just inform the 'uncle' at the inspection center that I'm scrapping the car in 11mths time sly.gifsly.gifsly.gif

Speaking of experience of an NA Auto , in my case I lost more (low end) than what I gain (high end) using a higher flow after market muffler.

 

However, my kakis on manual rides luv their higher flow. Red line syndrome? You will have much better satisfaction on a Manual tranny

 

Okay if you feel improvement, even though only in high end. that is good. Supposing, instead of the mods, u drive with gusto and revving hard, in auto, slam to floor every opportunity to go, I think you realise the standard form is not far off from the simple mod.

In a way, I couldn't agree more. I could easily got a ticket on the stock exhaust without knowing what speed I'm travelling. With the SS it just simply SOUNDS faster without the need of breaking the law. Ironical? So be it laugh.gif

whilst u may be contemplating this, u will also realize that the purpose of this cathylst convertor/ muffler is to reduce pollutants from car exhaust to enter into the environment.

 

if u look into the rear of white cars which r "operated", more often than not, u will find a yellow stain indicating the presence of acrolein.

you should be "made aware" that this is one of the substances which will be checked routinely

 

in any case, SAF rules still apply.

To get the best compromise, it's time to get an Apex'i Active Tail Silencer with variable backpressure! thumbsup.gif

this reminds me of the Supertrapps exhaust system for my ex Harley-Davidson, The are all stainless steel construction, and are fully tunable for a power/sound by adding or removing diffuser discs that are inside the exhaust canisters. thumbsup.gifthumbsup.gifthumbsup.gif

Oh yeah, I remember seeing those products, but for cars:

Removing discs decreases the exhaust opening and increases backpressure. This effectively decreases the powerband to create more low-end torque. It also decreases exhaust tone and enriches carburetion.

 

Adding discs increases the exhaust outlet and decreases back pressure. This widens the powerband at the top end. It also increases exhaust tone and leans out carburetion.
