Outer Limits 4x4 Board

hey guys
getting a new exhaust on my GQ. its the TB42e auto, and i have extractors. i was going to go 2.5" through a highflow muffler straight out the back, but have been told it could create a fair bit of noise and drone a bit. has anyone got any advice on what they have done and recomend?
cheers

hey mate i had a gu wagon 4.5 had pace makers and 2.5'' exhaust high flow sounded awesome all me mates loved it sounds sweet on limiter to

Make sure you shell out for a high flow cat too they make a fair difference to the EFI 4.2

hey mate i have a 4.2 efi patrol auto.

extractors to high flow cat and muffler, 2.5 inch crush bend system.

if u look up "reedy creek 4x4" or "4wd" on you tube u will hear my patrol its the white one.

it can be a little dronie over 3000rpm. like speeding up onto a high way.
but in low range it has a good note,
