If you run a centre muffler it's perfect. I did one on dvs jez drift car the sound that car makes is unreal. I agree with the ecu controll of the flap that would work and not cause issiues.

The Varex valve is a restriction when closed, there is a bypass into the muffler that flows around the valve giving near oem sound levels, even with only a single muffler. You can have the valve anywhere in its travel for adjustable sound levels using the supplied remote fob.

When open its a straight through muffler, up to 3.5 inch.

I decided to mod the 3.5 inch Varex muffler I bought.

I wanted my car quiet until boost kicks in so hopefully this works well. What do you think?

The rev controlled actuator accessory has been discontinued according to Xforce, so this was the best option, otherwise I would have to design a circuit, controlling the Varex motor with the car ecu.

It works, finished the exhaust today and went for a squirt. Its much quieter than the old 3 inch Legalis but the boost ramps slower now meaning the valve is opening too slowly. (even though the turbo spools earlier) I need a very soft spring in the actuator, a 2-3 psi actuator would be perfect but I cant find any. I might buy one of these and modify the spring tension.

Pretty happy with how it turned out, I got the larger pipe tucked up nicely. Hopefully there are some top end gains to be had too once its sorted.

Just a quick update i got my hands on a fairly cheep cat back 3" titanium trust exhaust it has one muffler im pretty happy with the sound on ideal its not much louder but when opened up it sounds real tuff and the raspy sound from the titanium is awesome

My RS*R 3.5 inch cat back is errr quiet when it's turned off haha

Mine was loud when I was just running stock twins with the Trust front pipes, 3.5in decay and the 3.5in cat back (rear muffler only) and stock dumps. Now it's running a single turbo with 3.5in turbo back... With a 2 inch screamer, I'm 24 so I guess I'll get sick of the noise fairly soon lol

Anyone tried the xforce 3.5" cat back systems before? I'm looking at upgrading my 3" and am considering one. They're under $700 and i'm struggling to find anything similar cheaper than that atm.

There was one that I saw come off a 32 GTR (Xforce 3.5in) it was almost as quiet as standard but also had a few nasty restrictions ie centre muffler arrangement. Once they were cut out and replaced with straight pipe the noise level barely rose however performance improved dramatically

    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
    • After @Kinkstaah debacle, I'd never want to try and get it right 😛
    • The hood lines up with the fenders. The front bar doesn't perfectly line up with the fenders where the wheel arch is. You have to 'squeeze' the front bar 'in' as it wants to naturally flare out and be longer on the sides. There's a few threads where people notice this when they only swap a GTR style bumper and front bar. Unless you have genuine OEM items - you may be better served getting conversion kits. There are GTT bumpers to fit GTR hoods. There are GTR hoods (non genuine) to fit the GTT bracketry. MAY
