Dunno Paul, just a personal thing i suppose. This will be the last exhaust i ever put on the car, so i want it to last. And sometimes i get under the car and make it all shiney again. Is that weird?

Give Peter a ring at Advan, they get some great TRUST front pipe copies made up...you would be hard pressed to tell the difference!

P.S. why do you want stainless?

I'm welding up my own mild steel job that runs a 3.5" dump/front pipe in to a 3.5" cat, from the cat runs a 3.5" pipe in to a 3.5" Magnaflow muffler that splits the flow in to 2 x 2.5" pipes.

Then from the intermediate muffler 2 x 2.5" pipes will run to the back of the car in to a 2 x 2.5" inlet and outlet magnaflow muffler.

2 x 2.5" nice little exhaust tips and it will be quieter than a single 3.5" flow slightly better and won't look like a damn Milotin. ;)

Magnaflow also make a 4" in that splits in to 2 x 3" out.

That would flow damn well. :rofl:

Generally Aus exhausts from my experience are crap. I had a $1660 D&T Performance exhaust made up that was absolutely sh*t house.

The dump pipe has massive slags splattered inside not to mention how the pipe wasn't stretched properly to mate up with the lower part of the flange, resulting in a 15mm V shape exhaust flow protruding lump smack in front of the compressor wheel. :P

Its been around 3years, now all the welds are rusting, but its s/steel?!??! :(

Depends on the setup... a few scenarios, using 350rwkw

a) if you are using an EXT Gate and plan to plumb it back 4" regardless

B) if you are using an EXT Gate and keeping it atmo... 3.5" would be pretty reasonable if your tight in cash, it would give you enough otherwise 4" if you ahve the bling bling

c) if its all int gated and stuff (read:nasty sh|t) then 4" regardless

As for WetGTR, from what ive taken in, the CAMS and stuff will be allowing you to do that power with the 3" as they are forcing it.

Put on a 3.5", or even a 4" as im sure ben has told you... and it would be VERY interesting to see the power difference which should be very notceable.

PS. Racepace custom turbos are the shiznit ;)

Weird....thats nuts!! But then again our TRUST 4" has got cat guts splattered all over it!

Yeah, ill be venting external wastegate to atmosphere, but if i get sick of that (or defected) i'd like to be able to dump it into the exhaust pipe at a later date.

Im actually having a hard time finding a 4 inch (101mm) stainless exhaust for my r32. I like the Apexi, but the N1 evolution goes from 85mm near the cat to 95mm towards the rear!!??? Apexi do a true 100mm exhaust, but not for the R32 anymore.

BTW, its $1100 for a cat back stainless Apexi, and $1700 for a cat back MILD Trust. WTF!

Yep your right R31Nismoid!

Ben did tell me that the exhaust system is becoming a restrictive point in my system. I'm now in the process of installing a HKS Super Dragger Muffler which is 3.5" and will have my EXT Gate vent to amto.

Wanted to go a 4" system but when you have the 3.5" HKS Muffler but sitting there doing nothing at my brothers place (was to be a future project of a Supra) , thought I use that and see what the results are.

I can tell you that atm I have 412awkw with a 3" system, then if the ext gate vents to atmo, I get 417awkw.

I hope the 3.5" system takes my power levels a little further. I will post up the results once completed.

The following modifications are as follows:

RB26 ENGINE

HKS 88MM FORGED PISTONS

HKS CON RODS

HKS STEP 2 280 CAMSHAFTS

WAS MAKING OVER 500KW WITH PREVIOUSLY FITTED HKS T51R

This is almost the exact same combination that i have put together. Will be interesting to see what it does on the dyno next week. I will keep you posted. Only thing that i can see is different is you have used 280 degree cams where i used 272 .

I would highly reccomend a Trust TR (they are 3.75 inch i think) they fit the bill for your requirements except for the stainless steel part which is really nothing major. The silencer system they have is very effective and they make room for large power increases.

Advan Perfromance in Silverwater stock them - 9647 1326

I have this. Got it from Nengun.

It is pretty loud... but tough sounding with the cams :)

It's a bit much for daily driving, and particularly highway work

nice on the track though

How much was it? Is it the Trust TR. Is that all you got or did it come with the rest of the exhaust (cat back including silencer and cat replacement pipe)? Im really interested to know becuase ill consider doing this as well.

    • There's no current law that stipulates that you cannot eat dessert with a soup spoon, although, it is socially unacceptable of course, shame on you But, there are emissions laws, which is sort of on topic to the OP's questions Things like emissions are, if anything, going to get stricter in the future for road registered cars I believe, 'Merica has yearly emisions testing in some states, the UK has it's yearly MOT testing as well which includes emissions Building, and purchasing modified vehicles may become alot more problematic if you want to keep them registered, how, if, and when each state handles this is anyone's guess  More food for thought really
    • I'm on the AD09, strictly on the street. They are a very nice tyre, have done ~16k km and are near the end, might make it to 20. They are, in my opinion, very much just a street tyre. I wouldn't expect them to be equivalent to some of the others in your list on the track. Although I'd be pleasantly willing to be surprised. My memory of the AD08Rs is vague enough, due to the passage of time, that I shouldn't try to compare them, but I feel as if the AD09 is not quite as "sporty" as the AD08R was.
    • There's a difference between "selling" a product to someone (which, if you walked into a workshop or bricks and mortar store and bought and walked out with it, is just the act of buying and selling) and rolling your buggy into a workshop and having them fit non-roadworthy stuff to the car. And for the latter, let's ignore any potential legal loophole arguments that the armchair lawyer might want to make to differentiate between supplying your own parts to be fit by the workshop or getting the shop to supply and fit. The workshops that have been dealt with in the US for this are in the latter category. It would be near impossible to try to charge/attack/criminalise a shop for selling "for off road use only" parts to someone unless those things were intrinsically illegal in their own right, or had other legislation wrapped around them, such as there is for guns, pharmaceuticals, etc. Well, no. And you knew your argument was silly when you made it. And there is. it might be somewhat harder in Vic, but then that's the price you pay for electing the long list of (unts that you have to run the whole shit hole**. But otherwise, you can put an aftermarket or otherwise tunable ECU into a car and get it run through the whole shebang of emissions testing as part of an engineering cert and, so long as the tune is "locked" afterwards, then that modification is on the list that is approved on the cert. But....it is an expensive process. ** Of course, the (unts who make up a large proportion of the population that eternally try to get around the rules are also a part of the problem and the reason that you end up with draconian rules in the first place. By contrast, SA was founded and the government and civil service set up and run by very sensible types (largely German) who set up good structures that enabled a lighter touch of government on the somewhat better behaved population. it is only more recently that we have followed the rest of Australia down the criminal drainhole of penal colony behaviour and now we have to catch up with mobile phone cameras and so on.  
    • Not specifically the revamp Toyos. In the past I've used Nitto NT01s, which were essentially the same compound as R888 with a different pattern (that's what the internetz said, so just be facts). I did like the NT01, progressive fade, didn't go from grip to 0 grip in a split second. If you look at the serious street/track guys, most are either on Cup 2, A052, A050, AD09, CR-S or AR-1.  
    • I have one of these! It is absolutely useless. It provides not nearly enough force on the bolt, it just slips over anything that is not finger tight. And if it's finger tight, you can use your fingers.
