Do you find any performance loss with the air box back on ? I ordered one of those piper x panels when i bought my car they are dry filters not oiled they have a extra layer of foam but when i went to fit it had a green panel in already doh so sent back for refund running open cone jetex now but on light throttle the turbo is to noisy

No not really, not that i can tell. I thought for a minute it wasnt quite as quick but it was because it doesnt sound as quick if you understand what im saying, due to lack of noise really. I looked at the speedo and its definantly as fast, also pulls just as well and i find it more responsive at low revs with the pipercross airbox setup.
