Thanks for all the responses guys! Pretty much know exactly what I'll be doing now, when it eventually dies.

Sweetas thanks guys. So if you had the option between stock brand new clutch and used for 5000ks Exedy Organic HD clutch, what would you choose? Those are probably my only affordable options at present.

That's awesome feedback man, thanks. Definitely cant beat that price point! Ps, how do you like the lightened fly wheel? How does it change the driving experience for you? Oh and How does the pedal feel and where does it engage? I am tossing up between the drews package and just the standard clutch (a few people are saying it works great and lasts for ages even with increased power). Please correct me if i'm wrong

Yeah well its pretty obvious when your clutch is completely worn and it slips. The whole point of the post was that i'm not sure how much life it has in it, and if it will be ok to tune given its current condition: 1. Engages at the top with very little range of control. 2. Seems to bite and have good engagement through 1st and 2nd gears 3. 3rd/4th/5th/6th is where i cant tell if the clutch is slipping slightly. The boost spikes to 1.5bar + and the car doesn't really match that in road speed, if that makes any sense. 4. Drove it up a slight hill on 5th at low rpm and it sticks, no slipping. So yeah, thats why im a bit confused!

I'd say that it probably didn't do that with your old clutch in the same scenario because it was slipping. Driving up a hill at 1000rpm on 6th with a good fully engaging clutch isn't going to be a good experience for the transmission which is probably why you're getting shudder IMO. You should probably drop a couple gears up a hill

How much did he quote you bro? Curious

Yeah definitely dont have the skills or tools for the job. The trickiest thing i've done is fuel pump, and that took me half a day haha. But yeah, wish i could! Friggin clutch change is gonna break the bank pretty hard

Cheers man, I have read this a lot too. So to confirm you got a stock exedy clutch, with uprated clamp pressure? Re Flywheel - I guess if im going to have to spend the money to get the clutch out, i may as well pay for a lightened flywheel too? Unless the gains are not noticeable, therefore waste of money?

I was thinking of going with them for a new clutch. Would you advise against it based on your experience with you current clutch?

Cheers bro. Feck me, $1000 for the HD exedy, and $640 for the flywheel . Thats like over $2k with installation..

Expecting 230kw atw and 450nm torque atw after tune aye

Unfortunately my plans to get my version 8 tuned may be halted by a weak clutch its engaging right up the top and I feel like it slips on high gears when boost comes on, but i'm not sure). Driven it up a hill etc on 3rd at low rpm and it grips solid, just feels that theres heaps of boost coming on but the car isn't really matching that in road speed on 3rd/4th/5th/6th, seems fine on 1st/2nd. This feeling is probably further exacerbated by a couple launches I've tried that ended up with the clutch way too hot and slipping into second pretty bad - Stunk real bad too, but started to bite again when it cooled down. Don't know if I should risk forking $1300 for a dyno tune and the clutch giving up on the day. The next dilemma is which clutch to get? I'm definitely keeping this car for ages and will expect about 230kw atw (hoping with my mods so far), and maybe 450wtq after dyno? Whats my best option for clutch + flywheel? Exedy HD, ACT etc. Read up a fair bit but dont have anything concrete to stand on in regards to durability, torque rating, and ability to handle some abuse. The last thing I want is to get it changed then need to replace it in 10k. Oh and who in Auckland would you recommend to get the job done? Been going to subtech for all my work so far. Any feedback or past experiences would be appreciated

Hahaha brilliant Bought a recirc valve and removed intake silencer

Hahaha yeah na not looking to swap out the twin scroll. Just trying to find out what header options there are to get that rumble, without sacrificing power

How did the tune change how it sounded? Forgive my ignorance

Haha for sure man! +10k cash

Hey guys, Been thinking about this for a while now, and have read up that this probably shouldn't be done. Nonetheless, wanted to know for sure from you guys and if there are any alternatives. I've got a 2003 WRX STI (V8), which I am pretty sure is twin scroll, and am pretty sure has EL headers (sounds like an evo rather than an old school suby - No rumble as such). Before i knew much about subys, one of the main reasons for buying this was for the good old suby rumble that we all love. Now that I've owned my v8 and researched, I know why its non existent (exhaust pulses etc.). Anyway, I am wondering if i can get the best of both worlds by switching headers. Will switching to UEL headers completely negate the positive benefits of twin scroll and possibly cause engine damage (or so I read - back pressure on one cylinder only etc.)? Was thinking of something like this: http://www.rallysportdirect.com/fits/2004-subaru-impreza-wrx-sti-2-5/exhaust-headers-and-manifolds/tom-193082-tomei-expreme-unequal-length-exhaust-manifold Is semi-tuned another alternative? I have heard the name floating around but haven't got any facts about positives and negatives, or even what it does. I'm guessing its half way between EUL and EL? Any thoughts and experience on this would be appreciated.

Add up all the money you've spent on it, then add it to how much you bought it for. Then look at how much you could sell it for. Far better off keeping it, or putting all the stock parts back in before you sell, if you do end up going down that path. Beautiful car and some sweet mods

Oh wow awesome! Great to hear from someone that has used their products! Thanks Tony I'll get my muffler changed to an Adrenalin R one.

Lol that is awesome

Thanks for all the info guys. I do have a 3 inch exhaust from the turbo back and was hoping to quieten it with an Adrenlin R muffler, as my current muffler appears to be unbranded. http://www.adrenalinr.com/productdetail.php?productID=522 Just to confirm, do you think this will definitely result in a noise reduction?

How did your adrenalin r sound man? Yours is a 7 inch one aye. After the 6 probably.

The previous owner had it install, cant see any branding but when i rung the guys who did the job (off the receipt) They said it was a big bore exhaust.

I guess the thread is twofold lol. Wanting to know if rolled edge mufflers are better or worse (or if its purely aesthetic). And if changing my current muffler (big more apparently) to an Adrenalin R one will result in an overall reduction in exhaust volume and cabin resonance. Sorry wasn't very clear in the OP

Oh really? I was going by their write-up which seems to have quite a few levels of sound deadening.: "The stainless wool breaks up soundwaves and creates a barrier preventing the packing from breaking up and exiting the rear of the vehicle prolonging the life of each and every muffler. The ceramic matting absorbs noise and heat preventing the fibreglass turning back to glass. The needlemat fibreglass blanket acts as the final noise insulator which results in quieter, deeper notes singing from the rear of your vehicle." Current exhaust was installed by previous owner, i think its a big bore muffler? Full 3inch TBE. Just a bit too loud. Borderline WOF fail as well.
