Another question about a Prodrive sports cat and decat.

Hi guys jusy wondering what gains i would get from our wrx if i fitted a prodrive sports cat down pipe, and a prodrive decat pipe, then got it mapped. thanks john

Don't worry about the results - just get it done!! Will transform the car

Got a 100 cel sports cat on mine - on the first remap with a good air filter and walbro fuel pump it was about 274BHP and much better to drive. Highly recommend Dynamix

Yeah would be going for a Dynamix map, just talked Lian round to improve the performance of the car, so watch this space, Thanks Robbo

i have a full decat blitz nur spec R and it drives better then with the cat in
i needed to put the cat back in or the cops would inpound my car but the car never drove as good with the cat back in so i changed again
now i hope the cops don't stop me anymore for being loud
you'll enjoy the change m8

just fit a full decat upipe down pipe

You will see very little difference between a good sports cat and a decat under 450hp. maybe a couple of bhp either way. But you will pass your MOT. If your not bothered and know a good MOTer go for a decat as there much cheaper to buy.

Well finally decided to go for a sports cat, well Lian has anyway , seen a prodrive sports cat down pipe and up pipe off a 2005 uk sti with genuine ppp for sale, are they any good and if not what should we be going for, thanks john

Totally agree with iddy, I went from a 2 cat down pipe to a single 100 cel sports cat and found a huge improvement in performance, I then went for full de-cat and didn't find any difference at all apart from the extra coin in my pocket that I got from selling the sports cat that is

Both changes were without a remap but I did check for knock and AFR's etc when doing this to make sure it was running fine.

thanks jonny thats very helpful,we are buying a prodrive sports cat and prodrive de cat up pipe, should have by the end of next week,got them for a good price and we want to fit them,but dont have the spare pennies for a map yet,so want to make sure it ok when fitted,do you know who could check the afr etc and roughly how much this may cost,thanks
lian & john

u will get nice pops and bangs from full decat, love mine
