I have done some research on this but i thought i would put this out there to see what everyone thinks. Long story short, the used header i got for my car is a pos, causing a nasty exaust leak. I have the oem manifold but don't have the downpipe (some a$$ stole my cat when i had the engine out of my car, it was still attached). So i can try to find the stock downpipe somewhere or but a new header. I really am intrigued by this tri y. Besides having to change the flange and possibly notching the cross member is there anything else i need to look for. If you are running this header what do you think about it.

 

I would get an ESP traction bar if the clearance is bad on the stock crossmember. I have heard some good things about the logic header though. One of the more knowledgeable H series guys in my area says its damn good. But, nothing beats a good ole dyno sheet.

 

i am going to either make a traction bar or buy the esp one. funds are limited right now though. I really just need to get this exhaust leak fixed before i get a sound violation ticket. I just hate to buy a pos ebay special that is going to rust apart in 2 years or never seal off. I found a dyno video online showing the logic header to outperform an rfm rep. and a bisimoto. But i wanted to see what everyone thought. Never hurts to ask for one's opinion.

 

I love mine in my H22 Civic. Stock motor, I/H/E (with that header), and minor tuning the car made 195whp/165wtq.

Unfortunately, I cannot help with fitment since I don't have a Prelude.

 

So it won't for cuz the stock cross member? I was looking at getting this header as well. I jave a 4th gen lude

 

I know that in the 5th-gen the crossmember had to be notched considerably, there's a thread on Prelude Power in the Prelude>General section.

Let's see if this link isn't blocked:

Definitely get a traction bar, I think the header was designed with Civic swaps in mind.

The tri y was fabricated for h22 civic/integra swapped setups. Thats why they dont exactly work with the ludes.
