those ports looked hand carved. I hope that's after you took to it with the dremel.

you could port match the manifold, but you would probably need to add some locating dowels.

yes, but nobody has posted the factory exhaust manifold weight yet

btw guys, stainless in it's pure form is non-magnetic, but it becomes slightly magnetic when worked, like making tubing, welded, etc. so the magnet test is not considered accurate

I hate to say it but grinding out that header like that didn't give you anything. Don't guess on how much something can flow by looking at it. Too many people try that and they never get it right. There is nothing you can do outside of the engine to increase flow in the center port. A dremel is also a terrible tool to use when trying to grind on steel. The sanding wheels are fine for finish work but that's the only useful thing about a Dremel on an engine.

Completely agree... My dremel is only used for cutting small objects or sanding after the grinding/stone work is done.

sorry

dremel is just an example

but I want to remove the little piece of steel


rotarygood do you think it's no interessant to try to remove the steel ??

I hope everyone is paying attention; remove the 02 sensor BEFORE taking the exhaust manifold off

nice


exhaust ports same to be bigger on the original ....

davefzr

Did SMRX8 ever get his car back?

therm8

just remember, bigger is not always better when dealing with port sizes

rotarygod

The exhaust ports on the stock manifold are much larger than they are in the engine. To make matters worse it's only the flange where they are shaped like that. They have round pipes welded to the flange and there isn't a very good transition to that shape. The stock manifold just plain sucks from a design standpoint. Don't look at the size of the runners and try to figure anything out from that. It's worthless.

sorry rotarygood for my poor english understanding ;

for you

I should try to remove some steel to open the port like the gasket port

or
no interest ??

thanks

rotarygod

Do not gasket match this!!! The gasket hole is enormous! I have no idea why it was made that large. The opening in the stock manifold is smaller and the actual ports in the engine are the smallest.

I just so happen to have an exhaust gasket here I'll overlay on a tracing of the actual engine port size so you can see the actual size difference and why not to match it. Leave the header alone.

florent75

oh yeh ....


thanks a lot

everything is clear with the picture


so my header is nice ...

ports are "dirty" but bigger than necessary ...

so no dremmel

thanks rotarygood

No nothing happened except i blew the nitrous solonoid and had to order one, I figure i will wait to the end and let you guys know the final numbers. but things are looking very good and the ric shaw unit works like a charm.I'm glad i didnt sell it when i had it on the f/s section.Oh and we did get a little more hp out of the computer but hes not done yet.

Cool! Keep us posted on the final results.

Sure will , I just didnt want to keep telling you guy one more day

davefzr

Sweet! Thankx for the update. I cant wait to hear your impressions about the car after it's fully tuned...

So, is this header a thumbs up or a thumbs down? Did they say the rise in HP is attributed to the header and not just the tuning alone? I just ordered mine from an SF dealer here. Got it for $250.

Moostafa29

Good price

florent75

on ebay you can find it for 249 $ or 289 $ ..


choose your price

cool keep us updated on the install. Are you planning on installing this yourself or at a shop. I would love to come by and check it out. I might purchase this header also, great deal imo.

are you planning on keeping your stock exhaust on with the headers also?
