Which Header would you choose & why?



Like many say, you can't go wrong with either but me personally, I would pay for something that has been track proven.
BTW...Jack make sure you keep next Saturday open. We have a special guest coming on up from Socal and it's not a E55

From your list, I'd probably pick FF, if they're still around $2,500. Proven track results on the fastest 55s, allegedly high quality (no direct experience with any from your list, but instead from the opinions I've heard, from respected members here), and a reasonable price point.

Also extending the O2 sensor wiring the correct way will cost an additional $$$
am not taking anything away from them, its just not as easy as some might think, so wanted to let you know

especially if you consider that to see adequete gains you should at least replace (or remove) the primary cats with high flows, even if you do shorties.The MBH headers can be considered bolt-on, since he adds the slip fit to the test pipe. You could cut the exhaust yourself, use the slip fit, and drive it to any competent exhaust shop to be welded. They are actually an option for the diy guys to save some money.
I was quoted a higher install cost for the Kleeman unit's, with cats, than the actual parts cost...lol.

The install went well but we did have one issue with the fitment towards the muffler. The problems was easily fixed and the rest of the install went well.
I believe Zod's issue was more of a miscommunication problem. Zod owns a CLS and Chris never made headers for this model which in turn makes sense why he had fitment issues.



Performance wise, the car seems to pull much more in the top end. It feels as though the car can breathe easier and is more responsive.
Sound wise, since I have NO Cats or resonators, it sounds beautifuL! Very aggresive. I can only imagine what it will sound like with an exhaust system.




I use to live in Gilbert. I emailed Chris at FF just waiting for his reply.
