AE101 exhaust dilemma

Postby Lurkin » Mon Jan 19, 2009 10:39 am

When I bought an ae101 levin in Oct 08 it was putting out 98 db from the exhaust, in that lovely headachy drone = at 3k.. perfffect for motorway driving! Ahh!

I went to pitstop who cheerfully put on a new rear muffler, replacing the straight through that was previously on it.

As described, the noise is around 92 - 93db, warrantable as promised. However the straight through has been replaced with a complicated muffler design, very restrictive. They said that the performance would decrease - but declined to mention that it would void the point of having 2.25 inch throughout!

The point is not to have sour grapes against pitstop, but more about what to do next. Obviously putting the old muffler back on will solve on problem - but not the other, and vice versa....

After having a chat to the old man (using to work in the old mitsi factory back in the day), he said interrupting the flow with an inserted pipe or divider can change the point of resonance and therefore solve the problem..... or putting more hotdogs in (there are 2 large ones already)

seems a little theortical and expense - I would have to chop the new muffler off to have a go... (have no means of welding it back on myself)

has anyone else heard of this/ tried it? given the new exhaust laws and the number of cars needing to adhere to them..

your thoughts?

What about putting in an offset straight through muffler at the back?

My 101 trackcar has 2 perforated coby's and an offset straight through perforated muffler and is pretty reasonable.

fair go - but your track cars definiitly louder than my car buddy!!!

actually really enjoying the lack of attention from the old 50.... guess I need to pull ma finger out and buy a welding device of some desciption - then I could just cut the barstard off and test away!

have a warrant in a month... might wait until after that and test a few ideas - will go to pick a part, get a couple of mufflers that are hopefully not completely raped and go hard...

unfortuantly there was a dual exhaust system there - but some bugger had busted it off just beyond the headers - otherwise I would have just pinched that instead...

we'll see I guess....
