I have an old school HKS Priest exhaust on my R33. I was thinking of swapping it but I like the style. It is a quiet exhaust and has a big old resonator. Does anybody have this type of quiet type muffler without the resonator? Would like any idea if it would sound raspy or not

I have retained an HKS Hi power muffler in my 33 gtr. It is 95mm in on the muffler, but the rest of the system was shit. Binned the rest of the HKS system from end of front pipe to start of muffler, which includes the resonator. I replaced it with custom 3.5" stainless. Sounds heaps better and is way less restrictive.

Sorry I'm retarded. For some reason I was thinking I read HKS Hi power or Hyper, then I re-read and saw HKS Priest. If you have one of these - you need to bin that shit ASAP. The muffler inside reduces down to something like 2.5" - that's why it's quiet. The resonator on or off won't do much with that muffler if you've got the full cat back priest system as they run a mid muffler too.

Most off the shelf Jap / Jasma mufflers have huge restrictions stepping down inside them, with a lot reducing to under 75mm. I'm annoyed my HKS Hi power steps down from 95mm pipe in to 85mm inside. Even the Xforce stuff here is no better either. Our white 32 GTR has a 3.5" / 90mm pipe in Xforce muffler and guess what - it even steps down to a smaller 75mm. I'm not even gonna try and sell that - it's going in bin where most Jap mufflers belong.

Good mufflers absolutely should not do that if you want to make power.

    • I’m here solo don’t have any hands to help so haven’t hit it with a timing light 
    • When you crank your car, and hit it with a timing light, can you see a steady crank timing?
    • Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).    
    • Car is on factory injectors/z32 maf/ q45 throttle body/ z32 ecu with nistune 
    • Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
