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!

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
