So I'm looking for a project over the winter, I'm just not sure which one to go with.

First off, 04 impala SS, mods are: k&n intake, 104 plugs, 180* t stat, intense shift kit, p-log, 3" catted DP, 2.5" magnaflow cat back, 3.4 pulley, 1.9 yella terra roller rockers, 130# comp springs, in car tune by overkill.

Now here's my question, I want to put in an intercooler because I know that will give me the best gains. However, should I be doing headers before* I do an intercooler? Or is my p-log and DP sufficient enough?
Everyone's 2 cents appreciated.

I say headers. ZZP powerlogs are only rated 'til 300 HP, and depending on your tune with that 3.4 pulley you are probably really close to that number.

I would go headers first.

When you do go with the IC, go full size. Most I know with the SSIC did it to save money and soon after all regret not spending the extra for the added cooling.

Headers.
Work on the exhale first, then the inhale.

Excellent, thank you. Now when choosing a new downpipe, what are the advantages/disadvantages of a cat? I'd like to eliminate it and already have rear 02 sensor disabled. Thoughts on that?

Advantages, possibly a few extra ponies, a little throatier sound

Disadvantages, you'll fail inspection (visual)

Ok great, not worried about failing inspection. So I think I'll save a few bucks and opt for the off-road downpipe.

And to reply to other post; I won't be getting rid of my resonator, just my catalytic converter. When I do get the headers I will be looking to sell my downpipe with converter, but that is another time, another post.

Thanks for the advice and info.

I have a gutted cat, if you like that smell of raw burnt fuel like the old cars have, you will be happy.

Personally it's a little strong, but I don't drive the car much Laughing

I prefer this smell myself. Especially coming out of an old big block. Very Happy
