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!

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
