Your standard type of High Flow Cat is usually a ceramic internal type, where the dearer Catco, X-Force and BPM 'Metal' or 'Metallic' Cats use a stainless biscuit core and flow a lot higher.

There is NOTHING wrong with X-Force Cats as above, dependent of course on the vehicle and its level of modification.

For the price, I don't think you can go wrong, and I have used one on my old GTS-T and had no problems at all with a significant performance gain.

I would say depending on your level of mods and how far you want to go... go a metal one... I bought a ceramic highflow... put it on... previously I had a gutted cat (straight through- all the inside bits taken out for max flow) going from that to xforce's ceramic was a massive step down...car lost a lot of power... but once again.. depends on how powerful your car is.

Adam

I might be able to help on this matter. I have an xforce ceramic bolt in cat on my car at the moment. I recently bought a "metalcat" weld in cat. getting it welded in on friday, getting the car re tuned on saturday, so ill post up a before and after dyno graph. I wouldnt imagine a BIG difference in power, but we shall see.

300ish extra cfm can flow thru the cat now, should probably see a bit, it will probably be noticeable.. cant wait for the results anyway

xforce make a cat that is about double than close to double that flow and price too, check to see if you got the oval type? or the higher flow racing cat (round barrel style)

I agree that it depends on mods, i have a hi flow (hi flow front vg30 rear) blitz fmic, jjr split one piece dump with a 3" the rest of the way, apart from the cat, that was still the factory 2.5", put the x-force ceramic cat in today, got rid of a mis i had (although i also did the cam belt no idea if that would have helped) power is now more crisp, boosts a little earlier and harder and is also a little quieter when idling, i would say they are a good thing, that being said my next engine im hunting for 300-350rwkw and will probably upgrade or remove the cat completely.

WRONG!

Have a full xforce exhaust, including cat. Running over 400hp on an rb25 for 3 years. What more could you ask for??? Flows well, good value for money.

Not wrong.

I put a 3" supposedly "high flow" Xforce cat in to go over the pits and it was crap. Loss of power and response, felt like crap to drive, took it out as soon as I got home.

I was trying to push 3L worth of exhaust gasses through it though.

Which cat are you running? a "High flow"? or a "Race" cat?

And if you went from a stock exhaust to a full Xforce exhaust then yes, it is going to feel a lot better but you have nothing but a stock exhaust to compare it to.

^^^ agreed

I took my HI FLOW x-force cat out for de-cat and perfromance gain was heaps better.

I haven't tried the race cat one with higher flow but i am sure they would be alot better much like a de-cat

      S15 Spec R

      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!

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
