headers question

Im getting some mixed answers so maybe I can get some help here.

After I had my Pypes exhaust inatalled (o/r x pipe w dual exhauat, cats) my mechanic suggested I get new headers at some point. Im also being told my stock ones are just fine. So to get headers or not is one question and the second question is shortys or long tube??

I looked into this a lot.... Shortys are same size as our stock headers u will see a little profmance gain but not a lot..longtubes always the way to go get a lot more performance but is a pain to install..so in short

Get longtube headers, but why would ur mechanic suggest headers?? Is urs cracked or leaking?

Want slightly better performance, get headers, if there's no holes and you don't want to sink $300 in headers then dnt worry bout it

Shortys=waste of money
Long=better performance

Put it this way, you upgrade your intake to a cold air intake, bigger diameter intake, more air flows to the engine, after it passes through the engine you have a lot more air or exhaust fume, So you upgrade your exhaust so you can let more fumes out faster
This is why most people would do a CAI, then exhaust system, then tune before their other supporting mods
And long tube headers really help with this, compared to shorties which really don't

No problem, if you'd like, you can snap a picture real quick of each and we can take a look, they might be rusty

I got the Pypes system and changed out the headers. Changed out the headers and felt no performance gain. Just a slightly different sound. I have had it with and without cats. Still a different sound. Barely any horsepower. Dynoed it barley makes any difference.

Here's what I did until i can afford LTs. Your mechanic probably suggested you get headers because our stock manifolds are prone to cracking. BUT dont get shorty headers, i fyou can't afford to get LTs then go to your local u-pull-it salvage yard and get the stock manifolds off of a 94-96 V6, the SN95 V6 came with headers from the factory instead of the logs we have. The SN95 ones bold right up to your block but you will need a shop to put a different size flange on the rest of your exhaust because the SN95 headers are about 1/4" wider from one hole to the other.

It will also only cost you about $40 for shortys while you save up for the LTs

Good idea .. so I have another question. My manifold was broke I cant even say cracked. So obviously it was making a crazy ticking noise. Now thats its fixed he said there will still be noise because of the air flowing through the pipes but I feel like I hear not ticking but light fluttering? Thats the only word I can come up with. Its mainly when I speeding up from going slow. Not at a fast speed either. When Im driving fast I can only hear the exhaust. Do u think maybe the manifold could just be f'd up?

Its probably a spot he missed, It also depends on how it cracked and broke, my broke right at the flange pretty much ( on the passanger side, My muffler guy said it was a design flaw with the A/C drain on the 99-04 model V6's and he's fixed a hundred or so of them...)but it's possible he wasnt able to seal it up completely. Again it depends on where it broke.
