Stock Exhaust Valve Switch?

Hey peepz,

I recently turboed my NA R33 and it wasnt running perfect. So mechanics told me it might be the stock exhaust and not flowing freely enough. So i ended up looking at it and realised that one of the exhausts wasnt even geting the gases out and it was shut through a valve/flapper type thing. This is operated through a cable and spring and connected to an electronic thing that pulls the cable. Anyway there is ment to be a switch somewhere to open and close it, i looked in the boot and inside under the dash and stuff but couldnt find anything that resembles a switch.

If anyone has came across this or knows where i can find it, that would be great. For the moment i have opened the valve manually and it made a big difference.

Im stumbled as why i didnt come across this before or hasnt ever been mentioned. Maybe not too many R33's have stock exhausts lol, with all the exhaust threads on these forums.

Cheers

The rasp everyone is complaining about?

This is Nissan's answere to help muffle it.. It should open under WOT

The rasp sound is that metal vibration sound yea?

I eliminated that on my old car by fitting a cannon which wasn't overly large and fit the dimensions that the rest of my exhaust had. (2.25 inch)

All that remained then was the RB screaming along and a solid exhaust note as heard above.

p.s I love the downshift at the end of the vid.. 150 metres away or so and you can hear it loud and clear =)

      Does that price include the rack time to straighten the frame and body and replacement of parts and paint, as well as the noise and emmisions testing  The last engineering certificate I had done, albeit about 15 years ago, was around $1000 for a few inspections and the certificate

      Geez, engineers fees have definitely gone up. Mine back 2007 cost me all of $300. Mind you, I had to go back to him a few times to get him to write the correct things on the report after he'd inspected it. Things like wrong exhaust size, wrong wheel sizes, etc etc.

      Can we see a scan of the original quote? The problem with engineers (and by this, I mean, all engineers across all engineering industries) is that there are "engineers" and there are "engineers" (you'll have to imagine the two different vocal emphases on those two versions of the same word. Engineering is a mindset - your farm kid who spent his life rebuilding the tractor will likely make a good engineer. The farm kid who spent his life taking photos of butterflies.. perhaps not. But on top of that mindset, the modern engineer has to learn how to write so that there is absolutely no way of being misunderstood. Proposals/budget estimates/quotations are one place where this is absolutely vital. You have to delineate your scope of supply with extremely hard boundaries, and anywhere where there is any possibility of not being able to have such a hard boundary, you need to write language that will cover you from scope creep, cost overruns, the inevitable interference of the client or their "engineer", etc etc. Now, if your clients are the BHPs and the Rio Tintos of the world, and similar, then you get good at this. If you are an automotive engineer, pitching work to the great unwashed masses, your skills in this area might not be well developed, because you're only dealing with knuckle draggers trying to get a big block legal in a Torana. And when I say "might not"....I'd suggest there's a better than even chance that any such skills might be completely absent. So, we might be able to look at your quote and see what the opportunities are for rebuttal.
