looking for some headers to put on my 04 TL

 

Sorry to disappoint you, but there is no such thing as the exhaust manifold is integral with the head on your motor

 

^ what he said

 

x2

 

theres a million threads on this

 

who makes test pipes to replace the precats?

 

wait a minute? Maybe I read wrong.. but are you saying there are no header or headers on the car????

If there are, and no aftermarket piece on the market, contact Hytech. They are a well known custom exhuast manufactuer who deal with many cars... Many of the Integra Type R guys use them, you will spend alot of money but will get a great piece that makes great numbers.

 

Well, there is no sepertate header that can be replaced. It is cast onto the motor block, with the Cat attaching right to it. The only way it can be changed is if the headers are cut off the stock block and new ones are custom fabed. The only thing that you can do to get a better exhaust is to get the 200 cell E-Shift Pro Cats and a better exhaust.

 

Are you kidding me???????

What crap.

 

Will the 03-06 Accord V6 headers fit?

I looked at them from many views, looked at both cars and look damn near the same in size/location.

Here are the headers:



Let me know what you all think, thanks!`

 

It looks like it may bolt up replacing the front two cats. But still not really headers, more of a collector. the individual exhaust runs have already been combined at the point of connection.

It looks like if you were to flange the rear tube to bolt up to the cat like the front is then the j-pipe project is complete

 

But still, I think it will bolt up, but am not confident... Anything seems better than those stock cats. I had my TL up on a lift today to get my 2.5" custom catback done,sounds amazing. And took a look at the headers, 3 cats in total, replacing all3 with this 2.5" SS piping is sure to help.

 

this would be for the track only

 

dude read the entire thread and all the post... even if they do fit you cant get them on because the headers are welded to the block on the 07's . Unless you have a shop weld on the new ones, but wouldnt sit well with your warrenty.

 

those so called "headers" are a POS. there have been a few guys with accords that have tried them and they had to have them cut, modded and welded to fit properly. they are not direct bolt on.

tl and accord share the EXACT dimensions from the manifolds to the 3rd cat.
