I am looking for advise from those who know, not guesses.

I have a 6 year old turbo ute and am looking for a nice deep note without too much drone and remaining legal. I am not chasing more power, rather more presence without loosing any power.

I've noted a lot of you remove either centre or rear muffler, both which seem to have issues.

I only have around $600 to spend and live north of Brisbane. A lot of local exhaust places say they can replace with cat back, some with single 3 inch, other twin 2.5 inch.

Whats your thoughts?

Well here's my guesses :P

I think I read muffler removal can sometimes cause drone (each car is different perhaps?).

Everyone will tell you to use the search button....single 3" is pretty much stock (FG).

There's a thread about single 3.5" vs twin 2.5" .... I think the main point is single 3.5" is a tiny bit more efficient....although twin can fit up a lot better.

At $600 pretty sure you're limited to the xforce and some others (redback & auspec or something was another brand I read recently)...but most choose xforce I think (people like the mainly quiet on idle/cruising and a little bark when pushing hard). Probably mild steel too? Last time I looked the cheapest was from "best mufflers" somewhere over East....but it was around $450-550; so if your exhaust place does it for $600 installed; then that's pretty good (apparently xforce needs a fair bit of adjusting to be perfect...as do many exhausts these days). Good luck!

His ute most likely has centre muffler with single 3" inlet and twin 2.25 outlets over the diff and into a twin inlet twin outlet muffler.

I am about to go down same path and planning to remove rear muffler and replace with twin hot dogs, it should require the least modification and with hotdogs hopefully it shouldn't drone

Finally had the centre muffler removed, thanks Robb Bliss Exhausts. Single 3" y piece to twin 2.25" (I think)

Sounds OK but is still a bit quiet, rumbles well when hot but no crackle when decelerating and is still fairly quiet. I thought that was because the exhaust exits so far behind the cab but was not very noticeable when wife driving away in it. (she did return!!!!)

Anyone tried swapping out the rear muffler for a free'r flowing? Its 2 in and 2 out pipes.

Definitely do not want drone, or too much attention from Cops.
