For the new Zen you could fit a K&N Filter and a Stainless steel Muffler. A Complete Freeflow system (4x2x1 style header + Mild steel muffler + piping) would cost around 6500 + fitting

I bought my esteem a stainless steel muffler. With a Stainless Steel muffler will cost you around : Rs. 8250

hope that helps !!

Hi,

Mahesh and myself are business associates and he does all my work. FE is directly related to how you drive and how heavy your foot is. Your FE will improve if driven normally.

Let me warn you though that a badly executed head job will not only hamper your performance but also your FE. PM me if you want any more info

Exclamation Headers.....

Are finishes like these tolerable in a header setup?



The pic below is just to show that it's a 3x1 header setup for a Matiz/800 engine!! Overall the pipes are bent pretty well!!

Edmund,

A word of advice, remeber that the exhaust posts need to be smooth and shiny - final grinding, in order for better flow. The intake final grinding should be a little rougher. The reason is - if the intake port is very smooth the fuel tends to stick to the walls resulting in lean mixtures and eventually a blown engine.

Also you need to have the proting and polishing done by an expert. If too much material is removed you will end up puncturing the water jacket - Big trouble.

Have fun.

@ Sideways: Got that ! thanx mate!

So the collector of the headers has to be polished and streamlined also?

And it will be done by a professional, im just getting the know-how!!

WIll one have to do Engine Decarb after a porting & polishing job? also will one have to get the Engine oil changed?
Has anyone who has done a porting or polishing comment on the change in FE?
I am very tempted to get this done on my Zen.

If porting and polishing is so good for the engine and increases the performance, why doesnt the manufacturer himself give us a ported and polished head??

What stops them from doing this? I guess this will some effect on the life of the engine, else why should the maker not port the head??

No maker explores the limits of an engine simply coz it needs to restricted to meet emission norms. Thatís the biggest concern!
