point was, this 'design' doesn't result in a drone

you could sell your exhaust and buy a Midori one - they also have another version with some sort of extra resonator or something as well, bit quieter.

But you'll need a muffler, so your choices are cut and weld or get a new one

yes, it's a Midori exhaust

Where did you source the midori exhaust from?

Here we go...

http://volvospeed.co...ne-elimination/

An old timer retired 80 yr old mechanic around the corner from me suggests that before trying on the wrap, obtain a tuning fork and whilst a mate is revving your car at around the 3000rpm mark, you place the fork at certain spots along the exhaust.

Wherever, the tines vibrate madly, the wrap can go on at those spots.

Well it won't cost much to try.

Meanwhile as Ash alluded to, I have a decent muffler on my Fujitsubo Ti system and...

JEZ says, it's quiet as...

...and there's no drone.

im running a ganador racing titan titanium cat back and a rsr front pipe and no drone what so ever. Its very quite below 4k rpm, Above 4k rpm and it sounds like the world is about to end! Im picking up a titanium midori front pipe this week for some extra scream :yes:

If you want that unique titanium sound without the drone looks like you might have to go a system like mine or daniel's

^ are the RSR pipes equal length like the Mines front pipes? are you going the 90mm Midori pipe? Ti or SS? i'm thinking of changing, but would love to hear the difference. Poss organise a time to have a listen?

Andrew, exhaust came with the car (as well as about every single other Midori item :D)

Drone is fixed with hemholtz chambers or branch resonators. Its math and physics, not guessing. OEMs do it, you should too.

Ah lucky mofo :P

I'm trying to decide between a full custom 3.5" stainless exhaust or one of those midori titaniums...

Hey mate no the rsr pipes look like this..

And the midori pipes are titanium 90mm. I recently bought them of the forum and should have them arrive this week. The motor is out atm but everything should be put back and tuned up by chasers end of this week/early next week. Would love to meet up. PM your number and will definitely organise a time for a listen

Are these an equal length design? I cant find much info on them that states what design they are. I bought them more hopefully for the sound, even though I have never heard them before or know how different it will sound to the rsr pipes I already have lol

I have a racepace 90mm on my 32 gtr. So quiet.

BUT it's mild steel and so heavy compared to these Ti systems.

To the OP, what is the criteria that you are looking for?

1. lightness

2. quiet

3. sound of ti

In order to help we need to know what your priorities are. I want quiet so saving 5kg isn't a biggie for me, and that can be had easily by changing over seats etc or removing the space saver...

Cheers for the help,

Im not fussed about weight, TI sound would be good... But im just after getting rid of the drone it has and making it a tad quieter as its a bit louder than what I thought it would have been.

Cheers :)

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
