Hey guys,bit of a noob on this topic, was just thinking of buying a new exhaust system, i found a rb25det (turbo) cat back exhaust, comes with 2.75 inch piping and a high flow cat, canon tip muffler all for a really cheap price, and was wondering if it will be droney on my n/a, or will it give a nice note? I heard 3'' exhausts are terrible for n/a's, all you end up with is a farty exhaust and nobody wants that =p

Also wondering will it directly bolt on to the factory flange or will i need to do some welding =='

Cheers guys

Haha yea second hand 100 dollars, looks like he spent a fair bit on it as well judging by his receipts, it was the only reason i was considering it =p Well if worse comes to worse i could always switch back to my factory exhaust but keep the high flow cat aye ? It has a hot dog resonator (i think thats the technical name for it)

probably going to drone like hell, even with a resonator. the turbo actually quietens down an engine, so while it would've been reasonable on the turbo, it will be loud on a natro. however if you find it too loud then you could go to an exhaust shop and have them fit a decent rear muffler (cannons are shit for actually reducing noise. an oval muffler is much better) or bigger resonator. or both, which is probably what it will need

Yea i asked him if it droned on his car, he said it did a little bit when he installed a bigger turbo, so im guessing the lagg from the turbo made it sound like a n/a with a 3 inch exhaust. But he said the stock turbo note was perfect. One of my mates told me to just install the high flow cat and the canon, and leave the 2.5inch b-pipe stock so it will quieten the noise with he stock resonator. Anyways not too fussed about it, just dont want to keep my hopes high that it'll sound good.

Cheers for the quick reply.

For 100 bucks you can't go wrong, in my experience (having owned one of the RB powered snails) they are all droney, some people claims there's isn't but I've been in alot and if they make any form of audible note outside it drones inside.....

Keep it quiet or put up with the drone :thumbsup:

Just an update on the exhaust guys, i ended up purchasing it for 120 bucks, ,I took your advice and installed it at an exhaust shop, got the 2.75 inch hot dog resonator cut out and welded a 2.5inch one, i also purchased a silencer and bolted that onto the canon. Now the car just has a humble note to it, no drone or raspy sounds at all. Its slightly louder than my factory but not by much (which is what i was hoping for). The silencer has this volume control thing on it, so i could make it a bit louder or more softer if i wanted.

Anyways cheers for the help guys, helped me a lot!

How does it drive compared to standard exhaust?

Honestly, pretty much the same mate, havent flogged it yet, fuel efficiency wise also still the same.

Putrid lol. Twincam n/a RB's in standard attire sound aids. Stock exhaust > all in this case OR 2.5" piping and two huge OVAL mufflers. A stock or very subtley louder exhaust will sound alot better then the raspy drone you will get from that exhaust.

      Me too. Apparently the new version of Invision will allow some customisation so look forward to a 'Love' reaction and a new 'Like' icon.

      Which injectors are you using? It's likely the fuelling is off also, so as above.

      R34 Series 1 And 2 Front Reo Difference?

      By LjB123 · Posted

      Awesome to know. I have a Series 1, and When pulling my front bumper off for the first time i realised my reo/crash bar was a bit worse for wear, and was going to try pick up a better one soon just so i can replace it. Someone is selling a full series 2 front bar and brackets for a decent price, so was going to probably reuse my brackets and install the new second hand reo/crash bar. I also have a genuine Altia body kit to do up, spray and put on, and not sure if that will use the series 1 or series 2 brackets for the front bumper, so having both will be handy, and knowing i can drill holes out to make stuff fit between series is also handy to know!

      R34 Series 1 And 2 Front Reo Difference?

      By Kinkstaah · Posted

      I should also say that the while they are different the only parts that matter are the center headlight supports and center bar from S1 to S2. The center bar will work, but the S1 has holes that clips go through into the S1 bumper. So if you were super cheap you could simply drill the S2 bar. Same thing with the side/wings. They have slightly different 'clips' but can be made to work. The center headlight brackets however, cannot. This is also where the GTR differs, which has a different center bar, and different headlight supports (to either GTT system), it also has different 'wing' headlight supports which is what I am calling under the headlight. However those CAN be made to work with the GTT Reo for a GTR front bar by a small spacer and a drill/tapping a thread into the reo because the bolt positions are slightly different. So people only really need the center brackets to go between GTT S1, GTT S2, and GTR if you are happy to do some tinkering.
