Hi folks,

Is there much to be gained in torque or responsiveness by replacing the S2 1ZZ's OEM cat with a sports cat? And would an ECU remap be required having made the switch?

No complaints about the car's current performance as such, just thinking ahead to exhaust replacement time...

Well the cat ought to last a looong time. My S1's done 90k miles and not a blip on last year's MoT emissions report.

So whilst this won't add many horses, if any, I'd be tempted to spend the cash on a nice stainless tailbox with a bit of character instead.

my cat is now a decat after 70k miles... it has no internals

LOL Ross.

Well I did think bits of mine must surely be leaving by now, but when the exhaust was off two or three years back, we had a squint and there was still a mesh in there !

Of more concern is the gradual loss of casing layers to rust...I think the next one will, in true pass the parcel stylee, be The Big One

OK, doesn't sound like a popular mod. Perhaps the factory cat isn't so restrictive.

TBH, I'd probably be better saving up for a set of forged alloys... more quickness, finer handling and a better ride (in theory).
