Thinking of getting one of those straight pipes systems for my r32 gts-t , look quite good, but I was wondering if there is anyone here that it is actually running one of those systems at the moment.

Interested to hear opinions of people good of bad, in relation to the sound and overall quality of their products.

Cheers.

one of the magazines have a cool artical this month where they test an rb26dett with stock GTR exhaust and then with their aftermarket one...

They GAINED 4kw by putting the stocker back on. Not generalising obviously aftermarket exhausts are generally better than the stock but its food for thought.

It is 90% track, 10% street car, so not too concerned about legalities.

How abuot stop destroying the environment and killing future generations. Whilst you're on the road, even if only 10% of the time, you risk I beleive it's a $15 000 or $25 000 fine. Might as well be prepared to sell the car to pay it.

How about you shut up and stay on topic. If you have nothing productive to contribute to this thread do not post in it.

Thanks

get two high flowing cats and run them in parrellel on a stright bit of pipe, never seen anyone do this but i rkn it would help flow a bit?

How can you run two cats "parallel" to each other on the same pipe? :whistling: or did you mean on two full pipes turbo back?

what MBS206 said is quite valid mate...

maybe you should consider the wider effects of what you might be doing?

one skyline tries to run no cat/muffler and drones at 100dB+ and then the cops turn on all skylines because they can

if you must, why not get this exhaust you want, and change it at the track before your session?

u got a point there mate but wat about telln that to holden and ford when they have their bathurst comps?

if his got a car thats used for track and he wants maximum output....im pretty sure his entitled to it.

even though i do agree with u.....maybe some extra thought should be taken into account about dumping bad gases into the air........again if its a track car....wat can ya do....its not like he can get EPA'd........can he?

exactly my point, all race cars have run no cats on their systems, and they flogged them for hours on end every weekend on every track of the world, and I dont see anyone complaining about that, or any goverment doing anything about it.

Maybe if you are such a tree hugger, you should put the idea forward to do EPAs to race cars as well.

Dont get me wrong I care about the environment, if it was a daily driver I would never think of runing no cat, I am not stupid.

how loud would a r32 gtr be with a straigh pip in place of the back muffler? keeping the same pipe and cat though out?

See the forsale in my .sig.

That exhaust is a bolt-in for a 32 GTR and was 105dB @ 3500RPM with twin highflow cats/no mufflers.

It's now 95dB @ 3500 with the 2 mufflers in it. Stock turbos. 105dB is, IMO, insanely loud; 95dB is IMO not.

Stock turbos do an awesome job of shutting up your car. But it all depends on pipe size and load.

If you're talking about just deleting the rear muffler and keeping everything else; you're going to

be restricted by the stock pipe size but you will probably pick up 3-5dB in noise.

It won't be _insanely_ loud as the stock pipe is quite small and you will still have the centre muffler.

Regarding the cat stuff; there's another thread I posted in showing what I believe the best legal

solution is here.

Saliya

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
