How are the CNT EL headers holding up so far? I'm very interested in these as a cheaper alternative to perrin's.

Default CNT performance Subaru STI Equal Length header

I have the eBay headers pictured above and so far I found that the slip joints leak like a bitch and the O2 bung stripped out when I dropped them to fix it. I only have 150 miles on them

The cheapness of the header comes from the poor materials used and poor assembly where you can't see it

Na, the $500 ones that still sucked. I imagine the 99 are made of cardboard

Updates on any cracks? I noticed that CNT says wrapping the headers voids the warranty.

No leaks. Car is actually at PSI Proformance and I'm getting it built n tuned. Should be ready for pickup in about 20-25 days. Dropped it off today.

Before the rebuild I was on 91 oct plus alcohol at 24 psi. 382whp/387wtq

After build I went without the alcohol (pump 93 only) at 20psi 396whp/370wtq

After I put about 5,000 miles on the block they said to come in for a 23psi map and should see 430whp/400wtq

The car definitely pulls harder and feels way more powerful. I did remove the alcohol kit, added TGV deletes, forged internals, gsc 272 cams,and ELH. Both numbers are from 2 different DYNO jets & tuners. Many variables came into play; different fuel & boost were the main 2.

I installed mine and fit decent. No issues installing them. I did a ceramic coating and heat wrap.

Installed mine 2 days ago. I can't complain so far, the car definitely feels like it picked up power with just bolting it on. The install didn't give me any issues, pretty straight forward. The only thing that annoys me is that it rattles at low rpms. Probably because it's thinner metal but other than that im happy with them for the time being

im currently on a stage 2 open source map at the moment. Spoke to my tuner and said im completely fine with the way it's setup now but it's in my best interest to get a retune with the header to get the full potential out of it.

Good quote from Chris at Killer B:

Adding a header, thereby increasing the engine's efficiency, will cause the fueling to be more lean under heavy load, which can lead to detonations, which is bad.

A tune will resolve this issue via A/F moitoring on a dyno, and the proper fueling changes. Another benefit to these changes is more power

I'm afraid of these.. I've always lived by the term you get what you pay for and these are by far one of the lowest priced pieces I've found.

If these were the same price as the Agency Power would you pick the Agency Power or the CNT?

This is my pickle.

I don't know the answer for that but for an update,

My CNT el header is still running fine. Got a FP Red HTA and made 430whp on the same dynojet that my 20g made 396.

I can't remember if you said whether you wrapped it, coated it or nothing?

Thread revival.

I just picked up this header and I'm trying to document a full before/after review of sound and performance. I have been doing a lot of back and forth e-tuning with my tuner to get the most out of my current setup, and then swap out the headers and retune. The goal is to have the headers be the only difference, not fuel, atmospheric differences, etc.

I got all tuned up yesterday and went to install the header today only to find that I ran into fitment issues with the oil filter on my 2006 wrx wagon. I found some good info on Perrin install that requires you to modify or replace the oil cooler, so I'm going to give that a go, but I had to put the car back together so I can still drive it.

I will post my own thread with pictures, videos, dyno graphs, etc and the most thorough review possible. And hopefully follow up with a long term review later on. If install goes smoothly, I plan to remove the headers to get them ceramic heat treated for better heat control, as CNT claims wrapping will void the warranty.

There is a version 2 of these headers I believe just released. Is that what you bought? If you do a video with sound and you get a strong itch to use a background music soundtrack please don't.

Looking forward to this!
