Hi All,

Anyone know what the X-Force turbo back exhaust systems that JustJap sell are like?

I noticed that they come with an adjustable silencer... Do they cut power down heaps? I'm assuming you would have to balance it between power and noise...

Any feedback is helpful.

Thanks,

Dave.

Ok lets have a look here.. the x-force exhaust is about $600 excluding a CAT.... another $200 for a half decent CAT and another $100 - $200 for fitting... so approx $1000 for a bolt on cheapish system... Personally you could spend approx the same kind of money you can get an exhaust shop to custom make a 3" mandrel bent exhaust, high quality dump and high-flowing CAT and you can also angle the cannon the way you want it... get 2 years warranty and is MUCH better quality... thats my 2 cents...

If your in the sydney area i will be more then happy to help anyone with getting them a great deal on a custom exhaust system from liverpool exhausts... what have you got to lose?? let me know if your intrested..

Regards,

Sarkis

They are good for the price, see link below for a thread I started on the Xforce systems about a year ago - heaps of info and a long review.

Friend had an X-Force titanium on his S15. Not bad for the money, the welds were a bit shit through and after a couple of times of scraping the ground ripped apart. You get what you pay for I guess though, so overall it was pretty good :P

I have a stainless Xforce exhaust on my s15. Because they are a mass produced item the fit is very average. I am going to get a custom cat back made up that will quieten it down and will fit a whole lot better. I just find it a bit noisy as well.

That said, a friend of mines r33 gtr has a 3.5in xforce from the turbo back which is nice and quiet and the note is perfect along with the fit.

If you are planning on purchasing one to run the silencer in it all the time I would stick with a stock exhaust. The level of back pressure the silencer creates can often be more than a stock exhaust.

An exhaust is only as good as its smallest orifice.

FYI - The custom catback I am having made up is mild steel with a stainless cannon and a very high quality straight though centre muffler (which will do almost all the work. Cannons do very little!). Cost is $600.

Hope that helps.

I picked up an Xforce turbo back 3" system for $650 including hi flow cat and stainless cannon. Fitting was about another $200.

The silencer cuts down the noise noticeably, but looks like shite. Without the silencer it was tested at *just* under the legal db limit at the specified rpm.

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
