Question????? - Exhaust noise level and pitch

[cameron boyle]

does anybody know how much difference to the volume and depth of the exhaust note a set of extractors would make to my exhaust. i have a 2 1/2 inch systim from the cat then split after the rear axel (no rear muffler) into two 2 1/4 inch pipes coming out through dual twin tips. it has a good note now and i dont know if it is worth buying extractors to enhance the sound. any ideas????????

it will make it deeper and louder and you will get like 8-15kw with a good pair of extractors

extractors dont actually do much to the zorst sound.. sound is more to do with mufflers... extractors will give u a small preformance gain tho.. worth doin!

extractors do not make a car louder if anything it sounds more quite, but it does make a difference to performance top end.
