more exhaust

[blackmonday]

There have been many threads regarding exhaust mods that increase aural pleasure at higher revs. Are there any mods that increase this at low/idle revs?

soprts car exhausts like the TVRs generally are of the absorption type rather than restrictive baffle type, these absorption ones are psrticularly good at silencing a low but continuous stream of gases exiting the system such as at idle or part throttle, but bad at silencing loud pulses such as at full throttle, hence most louder systems make most effect at large throttle openeings and least effect at idle. If you want a loud idle you'd have to experiment with a resonator which worked at that particular frequency. Someone might have a programme to work size and position of such a box out, but woulod imagine even then there'd be an element of trial and error involved. Plus chances are anything which increased the idle note would also increase the full throttle note aswell.

Thanks for the informative reply.

Would you (or anyone else out there) be interested in working with my car to come up with a working solution?
