HPS tubes, K&N Drop-ins, Injen CBE, and Z1 HFC's installed
 

So last night I installed my HPS post-MAF tubes and K&N drop ins, and today I got the Injen CBE and Z1 CBE's installed by a local shop. Sounds AMAZING!

I was sitting in the waiting area, and all of a sudden, I heard, VROOOMMM and I knew it had to be my car. So I ran outside to see them bringing it down off of the lift and the tech hit the gas with his hand. Man did it sound good!

Cold start is a very deep rumble, sounds great, can't wait to get complaints from the elderly lady next door (and I know she will complain), but at idle, it's barely noticeable, I doubt any louder than stock. At around 2000 rpms, there is some pretty serious drone - I assume due to the HFC's - does that get better with time? I can live with it, but I'm just not used to it yet. WOT sounds really great, MUCH louder than stock!

This is the first time I've installed an aftermarket exhaust, so I'm totally new to it... I've done intake mods before, so I sort of know what to expect there... Does the ECM have to adjust to the exhaust/HFCs/tubes/filters combo a bit before I really feel the power increase? I mean it pulls hard, but I haven't driven it enough to really tell yet. Would a tune benefit me much at this point? I really don't expect to do too much more to it...

yep, tune it. it will help optimize your torque and throttle response throughout the rpm band, and should get you a couple of hp on top if your into the numbers. Ecutek gets you some cool features too.
