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!

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
