No bigger than 2.25 or 2.5

Not many off the shelf skyline exhausts which are 2.25 or 2.5 unless you want a used gts-t stock exhaust.

Go source out a custom exhaust from an exhaust shop and get some quotes.

yeah will do asoon as i get same cash together.... i want a performance exhaust so probably round 2" would be best huh...

Is this for an RB20de or RB25de

2.25" mandrel would prob be best, with heatwrapped extractors - if your after performance

Even with an RB20de i would think with a few mods (cam/intake) you would lose top end with a 2", by heatwrapping your extractors and maybe some of your exhaust (with no/highflow cat and mufflers) should keep your exhaust nice and hot (hot air takes up more space but is lighter = flows faster) with a healthy back pressure.

Yea what he said, 2.25 and/or 2.5 is the optimum size for a gts.

Hey mate, I have an r33 with a RB25DE, I have a 2.5inch straight thru exhaust from the cat back with a cannon on it, The tip is 4" but the muffler itself is just 2.5. I also got them to put a resonator on, Its damn loud and still has the RB purr to it. Hopefully soon i can sus out some extractors and a high flow cat to complete the system, Sorry to thread hijack but could someone please help out with that.

Need extractors and a high flow cat for an RB25DE fitted.

thnks

josh.

    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
