i have hks silent hyper and love it.. dont let the silent fool you its loud as hell..looks chunky.. but i dunno about value for $$$ i think they are pricey compared to local ones...bolts up in less than a hr and was tested on the car so ya cant go wrong...

my r33 gts can standard with 60mm piping throughout. 2 1/2 inch piping is 62mm. so all i did was spend all my money a dayem fine muffler. magnaflow looks totalli dope. has two 4 inch tips. i'll send ya pics if u want. jus gimme ur email.

i'm thinkin of a zorst upgrade also, and yep 2 1/2 is the max imho. So paul can u please send pics of ur zorst to my email. [email protected]

thanks alot. :D

why do ya say it loses power if its bigger than 2 and a half? my hks exhaust was designed for my car and its 3 inch mandrel all the way.... you would think hks/jasma would know what there doin right..........
we're talking non turbo you fool :P

Owned :slap:

Generally 2.5 inch for NA skylines. Gregory has some sample of sound if you need to hear :)

cheers

yea n/a not turbo :Owned: besides 3" would probably b best if ur after top end. But i'd stick to the 2 1/2". Gregory me wanna hear sound, post it up please.

Cheers

p.s. Paul thanks for those pics man. that zorst looks mad and those effect from the neons looks shweet! and damn love those drift style wings man, fits in nicely!

I have extractors & 2.5" exhaust on mine. I have a mild steel 2.5" muffler in the stock muffler position. with a 4" stainless tip and looks pretty good without having a huge cannon muffler sticking out the back.

As for the muffler - all I can say is that go for the physically biggest muffler you can get as long as it is a straight through design with no baffles. I used to have a TRUST muffler before the it started to rust on the inside and then went to a smallish aussie made one (with baffles) - this was too small and loud and also lost some upper rev power. Then went to a larger aussie made one (universal 2.5" - straight through) and it's quiet again and has the same pull all the way through the rev range like the TRUST one. As for power output, a dyno run with old & new muffler shows there's bugger all difference between the TRUST and new aussie muffler.

So after tried and tested options, I say go locally made stuff as it is just as good a jap.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
