Hey all.....

I own a manual AU XR6 & have the following mods;
- 2.5 inch Mandrel Bent Exhaust
- Hurricane Extractors
- k&n panel filter
- ss induction kit

Is it worth dropin out the standard xr6 cat & upgrading to a hi-clow cat... or is the standard all you need?????

Thanks...!

Memphis...

Is the car a HP or VCT?

The HP has the standard Forte exhaust so it this case I'd say yes, buy a large bodied high Flow Cat.

I'm sure that someone will correct me if I'm wrong, but I understand that the VCT already has one so it wouldn't make much of a difference to change it out.

mate it is a HP.....

Also, would i be looking at much improvement if i went a Hi-Flow Cat... ????

Yes you will, because you have extractors and a 2.5" exhaust the only restriction now is your standard cat. The difference won't be mind blowing but it will let the gas flow freely.

I just got rid of my standard exhaust for a complete Herrod's system and the car revs and pulls so much harder than it did before.

As I said before in another post don't do it dude!
High flow cats cost the earth and reap much of a performance increase if at all.
90% of high flow cats have a bigger body and inlet/outlet pipe but the same cat brick.
I worked at walkers Aust the place that made your stock cat and the Ford ones are the best ones made there.
stick with your current brick it's not worth the cost.

Considering you have the rest of the exhaust done already it really wouldn't be worth the effort.

I think the difference would be unnoticable if you did, and as carazy said they can be pretty pricey for the amount of improvement you would get.

Carazy and Spinksy are right about them being pricey. I should have mentioned that, but I don't know how far you have looked into this.

I'm suprised you didn't get it changed when you bought the rest of the system. I believe that if it is within your price range and that's what you want, do it. As I said, the gains won't be that noticable but they will be there.

Sorry mate

I just put a high flow it, its the same as they use in the HSV's, only cost $185, and isnt much bigger than a standard cat, so memphis look into it, it'll be worth it.

Cheers
