Guys Need Help Here:

 

i wanted to try upgrading my Stock Muffler from my Rolla KE30...

google "exhaust backpressure" and have a real good read of it

 

if you do exhaust you should do a intake mod aswell (carby etc etc) so everything works together and makes more power

just a small increase from the standard/original system will see an increase in flow, resulting in better economy and better response. doing just the muffler won't have much affect other than noise.

what motor is it mate??? I'd advise a set of extractors and a 2inch or 2 and 1/4 inch full exhaust to make it flow better, then add a webber and you should see some form of gain,

Wow Thanks for the Feeds Guys....

 

by the way my KE30 is already in 4k engine 4speed Tranny....

 

i really do love this car its very compact and packs a vintage old school look..

 

but with just changing the muffler itself will just give me louder and crisp noise? right? no additional power or decrease in it?

 

but the will it sucks up my gasoline with that setup??

With my old ke70, i tried a few differnt things.

 

First off i cut out the resonator in the middle and had pipe welded in, This added a bit of tone/ rasp and went a bit better.

 

Then i had a Oval 2" exit stainless muffler welded on which made it fair louder and gave it a bit more power.

 

Then i had a mate mate me up some stainless headers headers which made an inprovement. But none of this effected fuel economy.

 

To me putting a 32/36 2 litre carby on a 1.3 is stupid. Unless you like wasting fuel it's pretty ordinary.

 

Instead my mate and i modified a 4ac carburettor to fit and it actually went pretty well.

 

Any questions Just ask

what did you 'mod' in said carby???

[Evan G]

get a 28/36 carby off a fiat 1600. fuel economy and power will improve!

Just the ability to make it bolt to the 4kc and all linkages being able to meet up
