Resonators

do resonators decrease power??

A resonator won't affect power much at all really, so long as you get one in the same size as your exhaust (3" for example).

I just had a small straight through (very slight offset) 3" muffler (about 20cm or 8" long with a side expansion chamber) thrown on my R32 and I haven't noticed any power difference. It's massively quieter now, no drone and I can drive it harder now without the po-po looking out their office window everytime I gun it = more fun.

All for the good price of $130 including raising the centre section of my exhaust which hung low, and replacing some hangers/rubbers.

Theoretically a little bit, but neglible in your case. Resonators just change/shift the sound of your exhaust system (natural resonance due to size and shape of exhaust system) to another frequency. Some times much quieter, or sometimes making it sound like a hyundi excel with a 6" paint tin stuck on the back

my resonator stopped the 100k drone with no noticeable drop in performance

my high tech muffler resonator dropped my 4800rpm db from 92-84. no noticeable decrease in power, no more drone
