What about the Japspeed K2 with a Japspeed Y-pipe? Anyone running this set-up? All these options, I'll probably not notice much difference in performance whatever I go for but every BHP counts

I have read good things about the Y-pipe but I also like the sound of the Scorpion (from what I've read if that makes sense ), can anyone suggest a 3" system to match the Japspeed or a 2.5" Y-pipe?

I am very close to fitting a scorpion system and Japspeed Y-pipe on my '05 UK Coupe but have a few questions that I hope someone on here could help with. The Japspeed Y-pipe has two 2.5" inlets and a 3" outlet, this will connect to the centre section of the Scorpion which has a 2.5" inlet. I am worried that any power gains from the Y-pipe will get lost by the build up in pressure at the step where the sections meet, my fluid dynamics isn't great but I can see that more resistance will build up causing the back pressure to be higher. Does anyone know the size of the outlet on the OEM Y-pipe is and would it provide a better flow if I was to use it with the scorpion system? Did anyone put their Zed on a rolling road before and after fitting either systems? I have searched this forum but have not had any luck yet (I am new here after all), I'm sure someone will give me a link where this has been covered.

Zugara, your zorst sounded great but convincing my wife to deal with the 'slight' extra noise wasn't quite so easy. Thanks for the tips and the info on selling the back box.

Have you all told you insurance companies about having a 'modified' exhaust or have you claimed that its a direct replacement? If any companies have charges extra, how much has it been? I have been insured with companies previously that have not had an issue with any mods up to a 10% increase in power.

Thanks for the warm welcome, I have had a fair bit of useful advice already. I have found out from a few phone calls today that only Nissan seem to make replacement centre boxes and they want £200 +vat for them! looks like a stainless system is the way forward. I had a listen to Zugara's exhaust last night, it is very tasty but I'm a little worried it could be a bit loud on a coupe for daily driving. I have found a Scorpion system but they don't include the flexy's, is this a problem to fit (are the existing flexy's likely to be corroded, need to check later)? I'm more worried about the sound and volume, I want an exhaust which is slightly louder that the OEM one unless a plant my right foot. I am also tempted to give a couple of track days a go, I've never done one in my own car (apart from a few touristfahren laps if the Nurburgring in my RX8). I know some tracks have low-ish dB levels, has anyone had any problems on track days or know the dB level of any exhausts? Sally, I would never suggest that a female in particular would curb the rims, its more the size of the car in my situation (Saxo footprint/ visibility easier to cope with). I hope I got away with that!

Hey Zugara, What exhaust are you using? Do you know anyone locally who might be able to weld up mine until I can convince my wife that we need a stainless system? I'm in Hedge End so not far away, have got a bit to do today so probably won't be able to come over. Thanks for the offer, I would like to catch up at some point if the offers open.

I took it to my local tyre and exhaust place when it blew yesterday afternoon and the guy though the pipe from the flange to the back box looked stainless, it might just be a recently replaced OEM box I guess.

I might look into getting it welded until I can get to a meet to hear them up close as you suggest, the sound clips on Youtube are pretty poor to be used as a comparison. Do you know if it is still possible to weld it as its right on the flange? It does sound good at the moment with the popping when you back off the throttle but it's let down but the broken exhaust rattle at low revs! Are there many members in the Southampton/ Fareham area and how often do you guys meet up?

Hi all. I've recently bagged myself a mint '05 zed and have been enjoying having power going to the rear tyres again after selling a 230bhp RX8 just over a year ago. I am loving the 'slight' increase in power and especially torque, the only problem is that I have to let my wife drive it and she's used to a 1.1 Saxo!!! She is learning quickly and we've managed 6 weeks without curbing the Rays. I have been scouting around the forum and found loads of very useful posts so look forward to spending many hours on here. I have been trying to find some information on exhausts on here but there is just so much out there I'm getting confused! My centre section has cracked/ broken at the flange where it connects to the back box, the box looks very new (possibly stainless but painted black for some reason) so I am after some options. Can you buy a stainless centre section and possibly Y section in stainless which will connect to my back box or if not which stainless systems are worth looking at, I could do with some prices if known. Cheers in advance
