i put a just jap bellmouth front pipe on recently and it bolted up perfect. lined up to standard cat position without any modding. this was on an RS4s

D.

how much heat comes through to under your passenger seat now if you removed a heatsheild? as i have amps underthere and JJ haven't gotten back to me about wether any standard sheilds fit(or top half if its clamshell) :blink:

i finally bit the bullet and got a custom mandrel bent 3inch on my s2 auto... it's flippin awesome but 1st - 2nd it hits the rev limiter twice and the gear change completes at about 100... has anyone had similar problems or is it time to work on the box?

the turbo is running in high boost mode with the shorted solenoid

Theres not much talk about mufflers being used and how they go with drown. I have a RS4S with a standed dump,cat with a 3inch SS to 1 muffler from hi-tech mufflers (not a canon) and it sounds great but i just cant settle with the drowning. Im thinking of putting a hotdog in there and see what difference it makes.

+ if your warried about the heat shield on a different dump why dont you heat wrap it???

Im using a justjap 3" bellmouth dump/front pipe into a 3" gutted metal cat, bolted onto 3" catback into 3" magnaflow resonator (hotdog) into 3" straight through kakimoto 'gtr racing' muffler

only drone noticeable is at around 1800rpm

free flowing enough for 250kw@wheels - rs4 auto

Some cool info on here!

I've got a S1 Dayz eddition that came with the optional Nismo exhaust, just curious if anyone knows what the pipe diameter of the Nismo units are, I could probably take it off and measure it up but that requires some effort :nyaanyaa:

Just thinking whether it's worth replacing if it's 2.5 inch or something, or just making up some blast pipes for track/drift days.

Anyone know if it's a full system, catback, or axle back only?

Edit: Shit sorry, I thought this was an exhaust thread ... maybe we should make a sticky with something like "What exhaust are you running".

My S2 came with the Nismo exhaust, from what I was told it's a 2 1/2 inch cat back. I assume the one on the S1 is the same. I thought about just replacing the cat and dump/front pipes to make it 2 1/2 inch all the way, but after doing some reading and asking around ended up making it 3 inch all the way through and love it!

ohk cool! Thanks for that.

So what made you make the switch, what are you running now and did you notice any power improvements from the Nismo item? (I suppose you would considering you swapped the dump pipe and such).

I had initially planned on getting the front of the system through to the cat in 3 inch, and then having in joing out of the cat back down to the existing 2 1/2 inch exhaust, but after doing a bit of reading on here and talking to my tuner, I decided to go 3 inch all the way. What I was told was that it would be too restrictive having it 2 1/2 inch and I was better off having 3 inch all the way to get the best performance. I am running a HKS Hi Power cat back, but I am not sure exactly what brand hi-flow cat or dump pipe, but I'm assuming they are X-Force or something along those lines. Something decent quality without being a major brand. As far as power improvements, I did a Nistune chip, fuel pump and boost controller at the same time, so it's a bit hard to tell exactly how much difference the exhaust itself made, but with that combination and no other mods apart from a HKS pod filter, I am getting 204kw at the wheels on 10psi.

Hope that helps

How loud is that Tim? I might even make something up myself where I can use the Nismo rear muffler for street, and blast pipes for the track.

It is a lot quieter than I expected. I actually noticed very little difference in car, and even outside the car it is not that loud. I think I hear my pod filter more than my exhaust lol

Just remember a oval muffler is always going to be much more quiet than a cannon. they're notorious for noise. not to mention drone.

my setup on my gtr. std dumps, jjr down pipes. xforce cat, custom catback with xforce oval muffler with titanium tip. very quiet on idle. zero to no drone.

bumping old topic but didn't want to start another one,

looking for an cat back exhaust fro my stag, can anyone confirm skyline exhausts fit and if its just a case of changing the hangers or if its shorter?

this seems to be the same shape, its off a r32 gtr.

cheers

I just had a cat back exhaust off a 4 door r32 fitted to my s2 stagea. Needed a few cuts to rotate it slightly, a section added before the rear axle to lengthen it and the hangars moved. It was Mild 3" and had no center muffler, just a varex on the end, so it was easy to modify, only cost be $100 to get fitted. Sounds great too :)

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.

      Yeah, I would have said the same. It makes me suggest that there are other things wrong, such that the ECU is totally unhappy with the broken sensor. The only other thought here is that maybe it is shorted, which might cause a different issue to the typical "disconnected" sensor.
