I was suggesting it was so loud because it was essentially a straight through pipe; ie has no mufflers.. What are we disagreeing on again?

haha, seems Aaron has confused you by confusing himself :P

Ryan. can you get a dB reading on that exhaust? Idle and 3000rpm perhaps?

Do like the Ti tips

Andrew builds his mufflers slightly differently. Instead of the traditional route, he uses sound deadening material around the outside. It does work, but he just needed to use more of it. Lessens restriction and gives a better sound.

Isn't that how most aftermarket mufflers work? You need a large muffler body, the bigger the chamber, the more low end noise it takes out. Hot dog or resonators are practically useless.

Doesn't explain the Blitz NUR exhaust

Not sure about other aftermarket mufflers, but I know most standard ones use baffles and other restrictions to lessen noise. Running a straight through pipe with sound deadening material around it should be the go if you use enough sound deadening.

I will get the noise down, once the bigger muffler is in we'll work out if we need to add another. Andrew prides himself on his work, and after having the car on the hoist today you can really see it.

Sounds like a few people are interested, so I'll get some group buy info.

I am still genuinely interested in the argument of bellmouth vs split dump? I have no idea, so I'm curious on the pros/cons of each?

I finally remembered to ring Andrew today, and he'll send me group buy details tonight.

In answer to another question I had, the cat installed in mine is a 200cpi metal cat.

Should get my new muffler in the next 2 weeks (assuming I get time to go round and get it fitted), but I have no doubt it'll be all sorted before group buy orders start happening.

Watch this space :thumbsup:

Ok guys, finally have the pricing for the AM Performance exhausts.

Dump/front pipe without cat - 480.00

Middle pipe with 200cpsi ceramic cat - 450.00

Middle pipe without cat - 250.00

Catback with muffler in the middle and single cannon style - 800

Catback same as above but twin mufflers 930.00

Titanium tips as per photos add 150.00

All is stainless steel (except titanium tips obviously).

Installation is $280 if you're in Adelaide, and prices are excluding shipping.

I have some group buy pricing if there is a number of people keen, we would need 4 people to go ahead.

If there is enough interest I'm willing to run a group buy, so let me know.

So complete system with Ti tips is just over $2k plus shipping?

I think maybe some db levels and a youtube clip for the sound might help.

Only reason I say that is because you can probably get a Kakimoto R or Blitz NUR and one of Scott's dump/front pipe combo's for that price, although AM's is probably a little easier for SA residents.

Still, very interested in the design and how AM are implementing the sound deadening. :D

Do love a well designed exhaust!

      Blue/grey smoke after idle

      By sunsetR33 · Posted

      I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.

      The old approach was to fill the cylinder/chamber with a length of rope pushed in through the sparkplug hole. The new approach is to connect compressed air to the sparkplug hole and fill it with enough pressure to push the valves up. Doing either of these things with the head on and the engine in the car is a lot less pleasant than doing it properly.

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Unpeeling the Orange

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.
