Anybody able to answer my question in bold blue above?

Thanks --- Bonzo

you get to choose which hp, bonzo. :tup:

i think i saw somewhere they were seeing about 3-4whp. with the post MAF you might get that consistently.

I found a dyno once - but I think it was for a G. One of those threads that linked to another...and another...and another. If I remember correctly, the hp delta was 7 (but don't hold me to that).

I've got the filters in and even those wake it up a bit. Feels like it comes up a bit faster. I'm going for round #3 on the Z1 tubes tonight. I haven't been able to get the damn things in yet after about 2 hrs. of trying. There's got to be some trick. Z1 did send me another set just in case mine are cut a bit long - very nice of them.

scott- when i did my HPS tubes i removed the front strut bar temporarily. also did a little bit of trimming on the tubes. hope this helps. :)

I ended up having to trim the passenger side about 1/8". Driver side fit fine in about 10 seconds.

The tubes + the K&N panels honestly made more of a difference than I thought they would. I can't tell as far as hp, but it definitely is punchier when you get on it...like it takes out some of the throttle delay. If you stomped on it stock, you felt it ramp up slowly. Now it's instant-more of an on / off switch. Kinda fun...

I don't know what a G3 feels like but I'm happy with this combo for under $200. I'm sure when my FI exhaust & cats get here it will feel even better.
