S2 Manual.

JJR Dump & CAT

Dodgy 3" J spec steel cat back with big mid muffler and HKS mega can (5" tip with a silencer thing that has never been shoved in).

Its quiet at idle but doesnt really have an RB burble.

I would like to maybe change the mid muffler to get a meatier sound but it's welded in.

I dont want it louder just sound better.

If you think your car is droney, try driving with the boot a little open.

I picked up a door for the house that was too long, it was the loudest trip home with everything being reverberated straight forward into the cabin.

Scotty's dump

Front pipe

Apexi N1catback

Sounds good between 3 and 5, bit droney otherwise, and makes some wierd 'wind exiting cannon' sound at full noise...


Will replace eventually

Just curious if anyone here has actually had their's db tested. Mine is a custom job from about 8 years ago now (previous owner). 3" from turbo back, custom made oval mid (apparently it was meant for a rotary I was told) and some kind of cannon up back. I've never had any attention from the police with it, but they are coming down real hard on anything that even looks modified around my area at the moment. Its not a bad sounding system and far from obnoxious but it does drone a bit and I'm still not sure its completely within db limits (it wouldn't be far over if at all). The canon on the back has seen better days now anyway and I got over the "canon thing" years ago. So I'm thinking of changing the mid and rear. Making the rear some thing oval with twin tips. Will look a bit more inconspicuous. I'm never going to be chasing massive amounts power from this car, one day if I can get up to 200awkw then I'd be happy with that. So I'm still going to keep it all 3" but want it quieter now with less drone. So something internally baffled instead of straight through is probably going to be the way to go. Anyone with a similar setup to this I would like to hear what you've got.

the one i posted in the youtube vid, is my straight thru system, from 1m away @4k rpm it did 106dB. (thats no cat, no mid muffler, just the end muffler from the HKS hi power silent kit.
now with a 170cell cat, and original HKS hi power system, i did 91dB @4krpm from 1m away.

tested at my mates exhaust shop with the dB reader

Hi I'm considering upgrading to a custom 3.5" cat back, car making about 450hp, wondering if it would benefit...over my current 3" set up

Pretty vague, there can be substantial differences between 3inch exhausts so how would we know how good yours is?....

Go on dyno , do power run.

Drop exhaust, do power run.

Figure out if you want to make new 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

      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.
