i dont like my 3.5" exhaust with a 4" cannon.

the exhaust is too big, so it sits too low under the car, and i hate the look of a milo tin hanging off the back.

im essentially after a twin 2.5" system, with a 3" chrome tip on either side of the rear bumper.

much like this.. (yes its a stinking holden, but it has the style i like :))

anyway..

where would i go to get something like this, and is it do-able?

is there room on the right hand side of the car to run the exhaust, or can twin pipes be run down the left hand side, and the second pipe crosses over to the right after the diff?

give me answers and/or suggestions!

ps. if it works, anyone want to buy a 3" trust dump + really high-flow cat *wink* + 3" -> 3.5" expanding exhaust, with a 4" tip? ;)

probably about $600?

its in pretty good condition, dump pipe is powder-coated, with a small scratch on the bottom, and the cannon has a bit of scratching and a small flat spot on the bottom.

yeah, ive seen that style... i like it better than what i have now.

however i still prefer the single tip on either side :)

might ring a few exhaust places and see what the verdict is..

if it can be done on a GTR, i cant see why not on a GTS-T.. both have the same exhaust channel on the left.

yeah it would creat alot of extra un-needed piping making it more expensive? the twin exhaust on the Monaro/350Z/300ZX etc is like so as its easier to run twin pipes either side of the V-shaped motor. The inline six of the RB25 make sense to have the single pipe down 1 side.

I hear ya mitchy - Love the twin tailpipe look :banana:

P.S. You wouldn't need to sell your old exhaust, just the rear section really.

You can get any exhaust shop to weld you up a nice twinpipe system (from say the rear-diff backwards) - the only real cost would be in the twin mufflers.

How you'd go with in-cabin drone is another story but!

Good luck, and don't forget to post pics when you're done!

Try Genie exhausts, they may be a little more expensive than some places but theyre generally competetive and always have a good end product.

i think street force built that LS1 R33 which has a cannon muffler exiting on each side. give them a call. i'm sure any competent performance exhaust shop could make it, not sure how much room you'd have for piping underneath the right side of the car though.

i was thinking about just doing the rear part after i posted..

just before the dif, and back, should be all i need, because its only really where a 3.5" mandrel bent pipe passes under the dif shafts does the exhaust cause any problems for bottoming out, etc.

emailed mettams and they doubted it would fit with the stock fuel tank.. but i reckon with a bit of creative thinking, ill get my twin tips ;)

ps. with the twin tips.. i was thinking about putting one of those apexi exhaust control valves on one side..

ie. when i dont need power or noise i can make it run off just one 2.5" exhaust, and when i want to give it a squirt, open it up for twin 2.5" goodness :D

just do what im doing with the stagea - 3 inch to the diff, then split, with a 2.5" going to each side, with cannons.

dump pipe, cat, length of pipe, magnaflow muffler, resonator tuned for 2000-2500 revs, or 2500-3000 revs to stop drone, then length of pipe back to diff, splitter, 2'5inches each way, to cannons.

brilliant. but expensive, maybe $1300 depending on brand-name parts or not.

      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?

      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.
