Hi all , my R33 came with a Nismo catback which is very quiet . It has the rear muffler with two internal perforated pipes through it . Can anyone say for sure if these are restrictive and if so what fits this system thats quiet and flows well . The metal matrix Catco cat will be the first performance mod to this car and it would be good to keep it quiet .

Thanks A .

It is better to have a quiet car as you will not stand out as much and wont and youcan still

hear your stereo over the car and you will gain a good boost of performance going to a turboback3in

as the nismo is only 2.5 inch and still fairly restrictive, system such a hks silent power ,apexi n1 and trust peII are both fairly quite untill youopen it up,will be slightly different with high flow cats and 3in front pipe.

make sure that ur nismo ext. is ont sportsmode there should be a little switch to change between the too.

cheers

I have heard that Nismo exhausts come in 3"? I have bought a 3" mid-section that I was told was Nismo.

I've heard they are quiet, but i'm also keen to know how much more flow you can gain from a noisier exhaust.

It has a single 4 inch tip with at least 3inch piping. Internally, the rear muffler has two pipes that i assume are to decrease restriction while remaining quiet. Also has a straight through middle muffler. Its not the "normal" nismo exhaust with the twin tip and butterfly valve setup but it is a nismo genuine cat back.

And i thought you didnt want a loud car :P ;p , quiet doesnt always mean restrictive, it looks like an quality exhaust.

The cat and stock front pipe would be more of a restriction than that catback.

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
