anyone can give me some advice ??

any other brand is more valuable ?? good flow good gain

I think the test pipes are probably about all the same.

Berk HFC might dyno a little higher than other HFC's -- there is a master thread with this info that is stickied, I beleive...

I have run...... INVIDIA TP's, GTM resonated TP's , CNT resonated TP's, FI HFC's.......
TBH apart from the quieter HFC at around 2800-3200 rpm, they all felt the same and all fit the same.
Have no worries about spending less cash, you can pick up used TP's as Westwood and they will fit ok and perform ok to.
Just FYI, the INVIDIA's came with the best 'install' package, not that the others did not give you everything you needed but I prefer the 'studs' in the INVIDIA package to the usual nuts and bolts. I did not throw an SES with any of them, but I do reflash my vehicle often so the ECU is getting reset every week or so due to hardware and tune testing.
