At the rear of the standard rear box there is an external pipe that exits and then enters the box again.

It looks like it feeds the exhaust gasses through the box twice effectively doubling the length of the baffles.

Would squeezing the pipe shut with some mole grips block the exhaust
or force most of the gasses and sound to exit more directly?

It would be interesting if the next time someone changes their standard exhaust they could try squeezing the pipe shut just to see what effect it has on the sound and performance

What do you think?






I just found this thread :-
Anatomy of an S2000 Muffler

which obviously answers my questions - not a good idea to close that pipe as you can see from the photo

Interesting to see the inside though

theres a few yanks that have cut off the resonators section

Drill a hole in it??

You'd be better off just buying an aftermarket exhaust.

Have you taken the top off the airbox?

Replace the Cat with a test pipe, that will change the sound of the exaust.
