Default Mods

I am going to get my first mods for my 02 Z28 i bought a few weeks ago. Im thinking about getting the Loudmouth 2 exhaust.
And thinking about getting an air box, but am looking at what kind. I like the look of SLP Cold-Air "FlowPac" http://www.afterthoughtsauto.com/copa20v8caf.html



Any thoughts.

LM2 isn't a bad choice, more tame than LM1.

Personally, I wouldn't bother with all that stuff that comes in the "FlowPac." The lid is the only thing I'd buy out of it, most sponsors will sell them for $90-$100. Save the $200 and put it somewhere else.

Stock filter will suffice, and the smooth bellow isn't worth much if anything other than to clean up the look of the engine bay.

I agree about only buying the lid. Most of the rest can be bought for cheaper.
As for the exhaust, I'd consider what the future plans are for the car. If headers aren't in the future, I'd get something louder.

Look on the classifieds here for lids, cai and stuff, should be able to find stuff alot cheaper than that! And i agree about making sure that you know if you want headers or not when picking your exhaust.

Not everyone wants the loudest exhaust in town. Some people want a good sound over volume.

Definitely a good piece of advice! I got my lid for $62 shipped from here, and it was just as good as new. Same with my LS6 intake, got it from $320 shipped.

$90 Lid
$200 CAI setup like SSRA/ FTRA/ or Chris1313
$65 Get your Throttle Body Port and Polished by a Sponser, (Damian or the SilverGhost)
$500-1500 depending on what you want (painted/coated/stainless) Headers/Y-pipe
$400-600 cat back
$200 Underdrive pulley
$125 Mail order tune from LS1tech sponser Frost

Build is good for around 50-60rwhp depending on how strong your engine is. A good estimate would be a little over 400hp at the motor
