Nismo R33 Gtst Exhaust .

[discopotato03]

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 , 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.
