muffler

[slighty_sykotic]

I think it's a cool idea, personally I have been wondering about fitting a wastegate type of thing to my exhaust to keep a constant amount of back pressure to keep noise to a minimum... yeah it'll use a bit more gas having to force the exhaust out, but I'm more concerned about noise than fuel consumption... at least at the moment.

I really think thats a bad idea... Just use a decent muffler and it will be quiet, no need to do something like that. Im sure the engine wont like having that much pressure

I found what I was meaning in an Aussie mag today at lunch.

thats quite cool poor engine when its closed tho

its just a fancy version of a bolt in silencer really, which is not legal to have easily removeable iirc. so same theory applies to this system here I guess.

indeed, not legal in NZ, but personally I think an adaptation of this could be a winner for those of us who enjoy track days from time to time.

a divert straight after(or even before) the CAT straight out the side, nice and quiet for the drive to and from the track, loud and un-inhibited on the track... and yes I know tracks have limits too.

for that purpose i'd still go for a muffler with bolt in silencer and spend the rest on booze $400-500 for that feature is a bit rich

heh... I'm lazy and I'm geeky... so I pay for things to be done or for them to be done in a techy way instead of doing them myself
