Thunder header or TSUDO ?

Im in Canada, it was $206 Shipped, I expect some duties when she comes (I get most of my stuff shipped in from the states, and Im familier with them. Im just not sure how much its going to be if any. Ive gotten a bunch of stuff with no aditional Charges at all. Do you have any idea what I should expect (The charge NEVER coincides with the Price I paid for the product, more on the "Value" Customes decides its worth)?

Im in Montreal also (Was that you at St Eaustach having tranny trouble last year?)
Or Do you have a few decals going down your doors?
I saw 2 Red P5's there last year.

if you gain the power down low, you still gain the power though dont you? still more than with the stock mani.
Rac3rX said:Why?
You shift at Redline for maximum acceleration, this makes your next gear catch arround 4000rpm's to 4500rpms, Maximixing the Use of the 4-1 header design, as they give benifits between 4000rpm and up. You got to love Gears.
4-2-1 designs will keep the gains Low in the Rpms, this is great if you want to pull a trailer or something, but not as benificial as having the power higher in the rpm,s.
Hypethetically if there is a total of 10ft.lb of torque gains from both designs, the only diference being the rpm's where the increase is applyed, the SAME 10ft.lb of gains will generat MORE hp if its higher up in the rpm's as a FACT. HP is power put to work.
In order for a 4-2-1 design to produce More HP than the 4-1 design it would have to generate a Much larger torque increase then the 4-1 design to make up for the low rpm's where its applyed, and I dont see that hapening with a bolt on replacements.

It goes without saying that eithor design will give gains, because both remove a cat & generate increased flow.
However
There are 2 reasons you want your gains to be higher in the rpms
#1 it will produce more hp higher up in the rpms
If you take the same gains (hypethetically lets say 10ft.lb of torque at the point of peak gain ) Its better to make that gain at a higher point in the rpm's as that will generate more hp. Remember Tq x rpm / 5252 = hp so a higher number in eithor will generate more hp.
What is hp?
Its a calculation of the cars power put to use over a period of time.
#2 You will be able to better use that increase of power due to the gearing.
To get maximum acceleration you s*** at redline (Or close to) When you shift into second gear it will catch arround 4000-4500rpm (As will 3rd, 4th, 5th, & 6th) If your gains are below 4000rpms then you will be outside of your peak gains during maximum acceleration. If your peak gains are from 4000rpm and up you will be inside your peak gains during maximum acceleration.
This means that the same amount of tq gains will generate more hp higher in the rpm's & the gearing of the car will take full advantage of it.
Lets take a real car for example, The Integra LX & GSR
The engine in the LX makes arround the same tq as the GSR, but the GSR makes it at higher rpms, and revs higher, this producing more hp out of the same amount of tq. When driving the GSR it doesnt FEEL faster then the LX but it is. The LX pulls as hard as the GSR because of the equal amounts of torque, but the GSR is faster because it Pulls LONGER.
GSR: 170hp @ 7600 rpm & 128 lb/ft @ 6200 rpm
LX: 142hp @ 6300 rpm & 127 lb/ft @ 5200 rpm
It's always better to make torque @ high rpm's than at low rpm's, because it produces more hp & you can take advantage of gearing.

Rac3rX when you suppose to get your header.

Hopefully this week, according to UPS its been at the border since Friday (They are opening her up and Charging me Tax and Custom charges most likely) Hopefully it gets out soon, but I doubt Ill be at the track this week. I should be all set the week after and get some 1/8 & 1/4 times.

When you get it will you take some good pictures of it out of the box not installed and measure the ID of the pipe.

Sure thing, Ill get you pics with the mesuring tape held up to the pipes, how's that?

Lol thanks im sure its about stock im just curious and want to see some quality shots of the welds.

lol that sucks.
Im at least Glad to know Ill have all the parts for tomorow (headers, mount incerts, & new exhaust clamp)
I also will change the oil and flush the brake lines filling them with DOT4, as I f-ed up mixing DOT5 & DOT3 (Yeah yeah I know...)
I should have 1/4 mile times slips up next week

Yeah its good to group things up.
"vtcs removeal"
Whussat?

UPS came with it today, But I was 5 bucks short of the 68$ Fees that came with it.
ARRRRRRRRR I held the Fricken BOX!!!
Soooo I will have it tomorow, Ill be waiting for him cash in hand.
man that really sucks. Didn't they accept cc or debit? You can always go pick it up yourself at their depot.
