hey all im going around trying to find a good exhaust to put on my Series 2 R33 and im coming accross heaps of different prices and wondering whats the damn diff??

Australias Best Tyre and Muffler - $1500 3 inch turbo back

Hi tech mufflers - $1875 full stainless steel system.

Then ive gone to auto barn and trust cat back 80mm item for $880.

Is there a big difference between turbo back andd cat back?? Can I get a cat back then later on turn it into a turbo back system? Just trying to justify the price difference. Im your opinion what is a decent price on a exhaust system? Do you think the above prices are a complete rort???

Firstly there is a fairly big difference between turbo back and cat back systems. Turbo back should make a noticeable difference to power over a cat back because there is as much, if not more restriction befoe the cat as there is after it. The stock dump is maybe the biggest restricion of all! Also the compliance cat is pretty bad too. Here is my suggestion Batmbl on this forum sells very good front/dump pipes a mild steel split dump/ front pipe is $395 then a highflow cat can be around the $190 mark (or around $100 for a second hand original GTR, not compliance,cat) then maybe a second hand cat back can be had for as low as $300 on the for sale section of this forum (mine was :() So all up we are looking at around $900 for a turbo back exhaust! Also on Ebay there are turbo back systems for around $700 not sure how good they are but..

Also in answer to the second part of your question all of these parts can be fitted at different times so it is possible to turn a cat back into a turbo back..I have been researching this a fair bit so any other questions feel free to pm me!

    • But it's much better to use a freedom unit that has four different possible meanings...
    • I would try messing with friction modifier to see if it smooths it out.  Just keep adding more until it stops chattering or grabbing quite so much. If you haven't changed the gear oil in a long time you may as well start there too in case that has anything to do with it. You might want to also verify the initial torque is set to the lowest setting too. Requires popping out one of the CV axles first but that's not too bad. Once you're sure the preload is set to the lowest you can try adding an ounce at a time of friction modifier until it feels right to you.
    • It is possibly 55 degrees for the Nismo version. I had a look through the manual and the stocker has a breakaway torque of 2.5 to 3.5kgm. Supposedly the Nismo LSD goes down to 5kgm when worn in but it is pretty grabby even with very little throttle. Worse when cold. So I guess you have three things. 1. Shims. 2 Friction plates 3. Cams Would think shims would be the easiest but Ive no clue how many tenths of a mm shim thickness change equals how many kgm torque. Also not sure if the Nismo friction plates are similar/different to stock or if they are the most of the source of the diff being angry. Think I can write off the Nismo rebuild kit for the standard diff as not being what I want.  
    • Yeah, it was a bit of confusion with me, I rang and asked if they had a boot for a soft top, and then the paint shop when they rang and were asked if it had a hard top on it, which it does, just not a PRHT....LOL Meh, whilst frustrating for all concerned it isn't a war stopper and should be a thing of the past in a week or two In other N/A related news, car is booked in at the end of the month for the cams, springs, retainers, harmonic balancer and retune  I might even pull the lazy arse card and get them to do a full service on it whilst it is there
