wow, glad I went with the GDP TT then, though I think the magnaflow sounds cool and is well engineered.
this is pretty typical of magnaflow crossover designs though, where you lose low end torque for more top end flow. the problem is stock 356 pushrods don't really have much top end imho compared to say a more modern motor.

Re: Stoddard's new muffler
Does anybody have any new videos of this system installed on their 356?
I’m curious if it will clear a PreMat full flow oil filter setup as asked earlier. I’d also liked to know if anyone has compared this muffler to a stock muffler on a dyno.

Re: Stoddard's new muffler
At the time I did my dyno comparison (see above) I also weighted the two tested mufflers as well as my original Leistritz which I've kept on the shelf during these tests. To recap the three:
GDP TP = 18.8 lbs.
Leistritz = 21.7 lbs.
Stoddard = 23.1 lbs.
BUT - the Leistritz weight is just the muffler and does not have S pipes attached. (it is net of the S pipes) so it likely will be pretty close to Stoddard all in.
