I'm chasing a quieter exhaust for my 33GTR. The one on it currently drones it's ass off and is loud on open throttle. It's a 4' inch from cat back, not quite sure how big from the dumps though. The car is running 1.2bar and pushing 340kw atw. I am interested in what people are using or what they have done to there current exhausts to make it quieter. I really want quiet as possible without disturbing flow capacity of course, and a silencer isn't an option.

Happy to spend up to 1500 for one.

Cheers.

so do you not want it to be loud even when on full boost?

my exhaust includes:

standard dumps

blitz nur spec front pipes

decat

tanabe cat-back (just one end muffler)

car has -5's still running standard boost and is pretty quiet below 3grand, then when you put your foot down it really starts to scream, sounds awesome imo.

ok, that sounds simple enough. If I just tell the muffler shop exactly what you said, are they going to know what I want or are they going to ask me more questions that I wont have any idea in answering. I'm not real fussed on it being lighter then air or being a japa exhaust, I just want it quiet through the rev range. You sound like you ahve done this, what has it costed you??

Thanks for your help.

As lot more than $1500 that's for sure :geek:

But it comes down to mufflers and labour costs. If any exhaust shop doesnt know what you are talking about then go somewhere else.

As honestly if they cant workout the biggest two mufflers and some welding, they shouldnt be in business.

If you are including a 4"-4.5" CAT as well then it wont leave you much room to move in $1500 IMO. It'll perhaps go a bit over.

Depends on the muffler cost really, and 4"+ CAT's aint cheap either depsite what EBAY might tell you

Ok, I was talking to a muffler shop today and there rates were quite reasonable I thought. See what they have to say about this idea in terms of cost. But I wont stay with the 4" I will just go to 3.5" like you mentioned.

Cheers.

Just ensure the mufflers are straight through, if they have kinks it will impead flow.

But any decent exhaust place will know this if you stress it to them (never hurts to check for yourself of course) :geek:

    • The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow 
    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
