I've got a 1641 TP engine.
I like torque.
I like good fuel comsumption.
I'm not going to fang the engine (much).
Which option should I take?

I have a genie system, just sitting around, waiting for someone to beg for it 😀 any extractor system is an improvement over stock, but make sure your jets are changed to compensate for the improved flow. you will have more power, shouldn't suffer fuel-economy-wise, and the torque will be there too. my genie system is gonna need an angle grinder to nip off the ends of the j-pipes that were welded on by the muffler shop. :cussing

You only use the standard Muffler system...
if its all You have.....

interesting about the jet upgrade with extractor exhaust systems... I didn't know about that..

Learn something everyday on AussieVeeDubbers...

I have a weber carby on single port heads and a standard Muffler..... I don't think I need to upgrade the jets just yet 🙂

Yeh, I thought the better breathing through the less restrictive exhaust will liberate a few more ponies - I only want to be able to over take the occasional bus and granny in thier Corolla (pre '85 mind you). I think the fuel consumptions should be better too as the engine has to waste less energy to push out the waste gasses..

hmmmm...yes.. jetting... if I just tell a carby or VW shop I have a 1641TP with a Genie exhaust system, they'll know which sized jets to sell me?

better off going to a dyno, then you can get a good idea of where the a/f ratio is. it may very well be wrong already.
