thankyou.

Akeenan, i know this is kinda off the subject, but have a R33 GTS-T and just ordered a Trust Power Extreme II turbo back with a 3.7" pipe... it comes with a baffle that sits in the back box, but now i'm worried that it will be EXTREMELY loud... i live in a high residential area with lots of old folk who may become scared... is that what you had? Any baffle? :eek:

Oh dear. The EPA and the elderly are certainly going to be unhappy. Is it unbearably loud? why did you take it off your car? You had a cat back didn't you?

I've ordered a turbo back, with cat replacement pipe (yeah yeah i know i shouldn't :uh-huh: ).... this will surely only be louder?

my car got complianced with that left on it...i wanted it left on so the place i got it done at just said ok....they knew it was illegal, but they didnt seem to care....

anyhow i got busted with it about 1 month later so we took it back to the joint and they replaced it for free with something legal....ive got no idea what it is all i know is that it is only 81db now and its got a 3 inch from the cat and a 3 inch tip...its all stainless steel. They said that my current exhaust is 100 times better than the other one but I would trade anyday!! however I would only get busted again...:mad:

and the dudes kept it and that was the last i saw of it

  • 3 weeks later...

So i've just got my exhaust... only the cat back section at the moment; the front pipe is on its way.

It is a 4" TRUST Power Evolution, basically straight through all the way (there is a pic on the last page i think). It is loud. Witout the baffle i couldn't drive around; it was so bloody noisy. Has an awesome note though; without the baffle sounded like a racer.

With the baffle in (after 1 day) it is not too bad, but will still be a fair bit above the legal limit i'd guess... Akeenan, must be the same one you had. Posted some pics too

I received an EPA notice in the mail back in October for excessive noise.

Someone else was driving my car when they passed a copy car who had pulled someone else over. My car pulled into a driveway a couple houses down as this was his destination.

2 weeks later, I received the notice and had 30 days to have the car tested for sound. Somehow, my car had to come in at less than 90db at 4200rpm.....

How did a car like mine pass I hear you ask??? It's a long story but let me tell you that a dead stock R33 GTR including exhaust reads at 89.2 db and not all Midnight purple R33 GTRs are the same as mine :P

Oh and BTW, they don't give you certificates with smiley faces and passes to stick to your boot anymore. I don't even know where I put my copy of the statement which I sent to the EPA.

Turtle, it is a bit low, but i have no problems on speed bumps so far coz my car is stock ride / stock wheels.

Leewah, hopefully i won't have to visit the EPA with the baffle in, but if i do i'd better find a friend with a silver series 1 GTS-t :P

    • Small update for the day... Turns out the intercooler and engine coolant hose kits are anything but complete....I probably should have counted better but it only really covers about half the coolant hoses in the car, it really just covers the visible stuff and pretends everything else doesn't exist (turbo water feed and returns and also heat exchanger lines through the 2 pumps and cooler) .In any case, I'm happier to have half reliable hoses than none, but a bit of a disappointment. Anyway...finger click (and 5 hours).....hoses in place, lots of spring clamps replaced with screw clamps, and engine coolant is on the pressure tester for the night.   Incidentally, upsized header tank is an Inifiniti factory option....not sure I'll ever do prod car racing in this but at least it is legal.
    • Just weld it onto the hot pipe. If you want it right after the turbo, put it right after the turbo. Or rip the comp cover off and drill and tap a hole into it.
    • hahaha glad I can rely on you two to go on a spiral at the drop of a problem! Some quick answers....the ducting is excellent top bottom and sides....everything that gets in goes through the coolers (noting the oil cooler redirects it out again, fair call if it is cooling 120o+) and the heat exchanger for the intercooler also has some scoops to pick up more than it's fair share too. I can't see going down the water spray track....no bueno for formal racing and a big risk for long rally days if you run out (plus I'm not clear if it is allowed there either yet).   Frankly, it must be possible to reliably put 400kw through a standard front end, the BMWs do it so I just need to work it out....I'm starting with reducing blockages in the way and adding some coolant capacity with a bigger header tank, flushing rad and making sure it was filled/bled properly (I didn't do the last coolant change); also taken measurements incase next step is a bigger/higher capacity custom radiator
    • wow, a completely stock GTR! I've got to admit, I have no idea from what you are describing....do you have  any idea where the "thump" comes from, and are you certain it is the HICAS light not something else like the cat overheat light?
    • nice work, welcome to the world of CAD! fabricating accurately in 3 dimensional space is beyond me....I almost always end up making something more than once...sorry I mean I extensively use prototyping
