I've just been through the original receipts. It seems to be a quiksilver sport muffler, k&n gt4 air intakes, 200 cell cats and manifolds (headers) from DAE.

I agree mine sounds more American and yours more race car.

Update - just spoke to the previous owner actually the back box is not quicksilver, they are lightweight GT4 items. He took the quicksilver off for being too loud 😝

Sounds just like mine, I got a miltek sports exhaust with miltek 200 cell cats, just a lovely sound.

I would be surprised at 10bhp for filter change alone.

didnt the factory quote +20bhp for the N400 kit, which was a pair of airboxes/filter and run on 97 ron?

Are the filters easy to fit?

Yes, but you have to dismount the front bumper and wheel archs, I mean is laborious but not impossible. You gain about 10HP and more exhaust sound.

How are you going to gain ANY BHP by replacing the air filters? The air intakes are on a tortuous path to the injectors. Its even as if yo can get any 'Ram Air' effect at speed.

Not to be pedantic, but the air goes to the valves, not the injectors. And it is not about achieving a ram air effect. A filter of any kind represents a pressure drop to the system as a whole; the more restrictive the greater the drop. And the greater the drop, the less pressure is available to charge the cylinders on the intake stroke, hence less power.

Now, how restrictive are the OEM filters as compared to something like K&Ns, I don't know, but it would seem to me that 10 hp would be a lot more than is possible unless the OEMs were totally clogged up to begin with.

Good points, I'm sure that the K&N sticker is worth at least 5HP though? That's what the advert in Max Power claimed.
