RB20 + turbo + good exhaust = :jump: (read shit loads of power & fun)

simple equation but i've never actually investigated the exhaust part myself...i'm after some help / advice with a new exhaust system for my r32 gtst.

I want as much power gain as possible and for that really loud RB20/25/26 "howl". Do i simply need a cat-back system or do need dump pipes done as well? I have an Apexi PFC running the show and boost is up to about 10/11 psi...any info would be handy and if anyone knows any reputable, no-bullshit workshops in Sydney that'd be a real help too...

3 inch exhaust from the turbo back. (not just cat back)

mild steel or stainless.. doesn't matter..

small (possibly cannon type) muffler.

3 inch Hi flowing CAT converter.

NO resonator muffler (they just quieten it and you want it loud)

that will give you the maximum power and loud noise you are after..

workshops - any known exhaust place could do it..

or you could get it all japanese... but they tend to be quieter..

Speak to a guy on these forums with the user id BATMBL.

he can get you a good price for the CAT and front/dump pipe.

then buy a cannon muffler and take it all to an exhaust place and ask them to fit it all and make up some 3 inch straight as possible piping from cat to the cannon muffler you bought.

then you have what you are after..

i found getting my 'line "loud" is bit hard,

i got 3" front pipe, 3" hi flow cat, 3.5" cat back with a 7" barrel

took the resonator out coz it was bit quiet, its bit louder now but still not as loud as i thought, i like it though how in the cabin its still nice and sports but at hi revs yes it screams...

cheers...ben.

That's right, they sound much better than the RB25. :whip:

you think?!

your opinion, but i think the exhaust note of the 20 is quite boring. whereas the 25 as more character. havent heard many 26s though.

ive had 4 exhausts on my car and havent really been happy with note from any of them. they need lumpy cams to sound good. nice and racey.

Thanks dude - one thing i forgot to add was roughly how much a set up like this would cost if i use mild steel for the exhaust...any ideas?

front/dump pipe in one cost = about $250 I think from user on this forum BATMBL.

CAT = $200??? from BATMBL again.

catback system custom made with no resonator muffler and a small stainless cannon muffler would be about $400 - $500.. (I got my piping with resonator muffler for $250 and I had my cannon already...

I got my piping done at

Carline Mufflers at Belfield.

Owners name is Robert.

9750 6281

they have some mufflers you can chose from there if you want or buy one yourself from an online store and get them to weld it on.

so all up, worst case senario...

$250 dump/front pipe

$300 cat

$300 cat back

$200 muffler

about $1000....

I just had done my exhaust on the weekend. 3" turbo back with i think 5" muffler n 4 " tip.

I got it done at liverpool exhaust. I would definitively recommend them, very friendly service, great work and fairly cheap. I cost me $1000 for the mild steel pipes and stainless steel muffler.

The sound is great, loud and rumbly. At the beginning I thought it was too loud but I’m getting use to it.

Now I get 3-4 psi extra boost.

If you go ask to speak to Jimmy and say Ned with 4 door R32 sent you.

      Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.

      Maybe you should do some more reading.  Google positive effects of ADHD and you'll get your answers.  One of my personal downsides of ADHD has been talking before I think.   Maybe you have it too?

      Excuse me for butting in....but which part of ADHD can be considered a superpower? I would have though it far more likely that some ASD comorbidity is more likely to be contributing to an ability to hyperfocus on something. ADHD being aimed somewhat in the other direction. My shed looks like your shed. My whiteboard list of unfinished projects has entries going back 15 years. I know what you're talking about - I just struggle to connect ADHD to the results being discussed.

      Thanks for reaching out!  It's a blessing and a curse at the same time.  I'm undiagnosed but it doesn't take a rocket scientist to see it in me... I have more half started projects laying around my house, shed, garden, etc taking up space and money, destroying aesthetics than if I added up all of my mates projects together. But, ADHD gives me the ability to hyper focus on things that no mere mortal could even  comprehend.  A recent pool build is an example of that....  I dont know anyone else that would be dumb enough and focused enough to take on then complete something of that magnitude. I call ADHD a superpower but it can equally be completely destructive if not controlled and focusedon the right places. Addiction is a major concern to ADHD people and thankfully my addictions have been no worse than projects, XBOX, chocolate and being an arsehole! It's often hereditary and my 13 year old son is currently learning how to drive it at the moment. Keep lurking! If i can finally finish this bloody thing at some point it will be a win for all of us ADHD'ers! 🤪

      I've been quietly following this thread for ages, but this one got me. Since my ADHD diagnosis (and associated learnings and prescription) I'm way less inclined to wade into forum yarns when there are better things to do with my time, as half the time I'd end up in some kind of forum debate even if that wasn't my intention. I've not lost the ADHD "superpowers", just am a lot better at directing my hyperfocus into slightly more constructive things, but haven't stopped quietly lurking in here in my spare time.
