Willalls have made one for me but havent had chance to get it fitted yet.

When I drove Keirs I didnt think the drone was too bad, but I didnt drive it around that much.

It isnt bad enough to want to pull it off is it?

I have fitted one as well........... I agree with GGTTRR the Willall Pipe sounds awesome under power, however, I would have to say there is a bit of drone around 2k rpm when you are using partial throttle (more so when you are in 4th, 5th or 6th).

Still when you hear the sound it makes when you are changing down though the gears (with the blip) nothing much else matters.

I wuold fit it (really quick job) and try it, you can alwasy replace with oem if you don't like it.

And no I won't be pulling mine off

Cheers

Is anyone in Qld with one of these mid pipes willing to meet up to help me decide if this is the right product for me?

Challenge Street Spec Y pipe : good quality pipe, no drone, good gains. AU$1050 landed at your door.

Thats good to see.

The WR35MP Willall Racing Midpipe made in Australia by Australian Fabricators (not China) using high grade stainless, full length flex joints, TIG welding, and featuring our internal deflector plate to dampen noise without adding the restriction of a muffler(s) is $800 on your doorstep. Great comparison

Thanks DiRT!

Great to hear, this pipe is also one of the most popular and consistent re: INDEPENDENT dyno results Stateside :D

There are a couple of reasons for this. The first is that we use a reversion 'stub' in the pipe inlet to promote turbulent rather than laminar air flow the moment the exhaust enters the pipes. Secondly is we use the diffuser in the Y section which is a carefully calculated length of flat plate that in effect balances the resonance and noise of the system. In other words we can have the same db reading as a lightly muffled system without the restriction, weight, and expense of adding 'cans' to the system. Thats the difference, we like to engineer stuff with a solid thought process rather than just make something that looks cool and shiny :down:

Very nice! Challenger is designed and QA in the US, fabricated in South Korea, not China.

It has two resonators on the Street Spec and no resonators on the Race Spec, which looks similar to the above, with shorter flex joints, wider Y-Collector, same power delivery as Street Spec but louder.

I would pay $250 more to guarantee no cruising speed drone, as it would drive me mad and force to remove it and flog it on ebay for half the price.

These pipes are polished so they look a bit better finished, not that it will matter much to most.

Ha Ha. Yes I had the Willall midpipe fitted today & my wife is well pleased with the extra girth & increased thrust.

I have done just over 1000 kays with the stock system & I love the new midpipe. It sounds almost the same on start up & idle but when you put the boot in it sounds much better & feels like a real performance car. Very pleased.

I was concerned it might drone a bit but have not noticed much difference at all at cruise speeds. It only seems to make the sweeter noise when you are on the throttle & that is exactly what I wanted.

The WRX STI that I dusted off this afternoon seemed to agree with me on the noise factor. He just loved the sound & made sure to let me know at the next set of lights!!!

I was lucky enough to be able to do back to back noise testing today as I was able to cruise up the Gorge this morning & again this evening (for those not from SA this is one of the best "hammer" roads in the state with lovely sweeping bends & cambers up in the Adelaide hills) & the increased engine note is fantastic.

Full marks Willall. Great product. Great price. Anyone else out there that hasn't got one of these fitted yet - dont hesitiate. As Dirt Said....... Aussie Aussie Aussie.

Yes, I was amazed by the difference the middpipe made to your car.

And you are a top bloke for sharing your R35 experience with me. There's too many pretenders out there that are all talk.

And credit to Willalls for contributing to the experience with their best.

If you are around the Sunshine Coast at all give me a call and you can have a listen.

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
