Is anyone running these? (I did a search. MILAN! lol) and didn't see anything....

Just curious if anyone knows how they are. Fit, finish, etc..I thought I read on one of the other forums people are running them....Since I am not a PEAK HP guy and want more area under the curve I would think these, based on what I know about TRI Y's, might be a good alternative for many folks.

I wonder if all the sensors work without having to turn anythign off.? Thoughts anyone?

Never heard of them until now. If someone has a link to them, then post it up. I wonder how much they cost as compared to the others. I love my Kooks, so I feel the price was worth it, but I still think that headers for the LX's are overpriced...just like alot of the other parts are for our cars. The sensors work with all the headers, but will throw cat efficiency codes due to the higher exhaust flow. I guess noone has or is legally able to adjust the tables in the PCM to allow the rear 02 sensors to be enabled and not throw codes, but hopefully somebody will do it soon.

Although the price is nice would still go for Kooks for 2 reasons: those look like shorty's where Kooks are long tubes and Doug's are 1-3/4 primaries versus Kooks 1-7/8.

I read the 2 threads over at LXF, but I wonder why nobody has given a full detail reply of what they think of them. They definitely look pretty, but I'm not convinced they're as good as the other long tube headers on the market.
