Headers for lowered cars. So, I know that SLP's are the lowest hanging headers out there. But, how do the others compare for ground clearance. Since my car will be lowered, ground clearance will be my deciding factor. Should I just go with Mac's setup? Opinions appreciated!
It won't be the headers that hang the lowest...it is usually the y-pipe (or x-pipe). FWIW, I run Kooks headers on my 1.5" lowered car. No scraping, but I've scraped my 3" pipe that comes off the headers on the driver's side (that is my lowest point).

I'm lowered about 2 inchs with the pacesetter LT headers and ORY. Barely scrape, but if I do its the Y pipe section on the drivers side. I kind of want to add CATS back onto the car, so I might go have a custom built y pipe in 2 1/2 inchs.

i have sportlines (~2" drop) and have MAC headers w/ carsound catted y-pipe. i dont have any scraping problems, only if i go over a huge speed bump straight on. but when driving with a little sense, i havent had any trouble what-so-ever.

There seems to be a difference in powerbands between the two but both can generally achieve the same peak power level. I would suggest going with longtubes if you can get away with it, but for someone that is lowered this header works very well. I ouldn't suggest the cats with he macs as they flow very poorly.
I'm pretty sure the gains have more to do with either how your computer adjusts for them or how well your car has been tuned after the fact. My car gained little from my Kooks LTs (as was shown by my track times), but a little time on the dyno showed that my A/F was way off and my timing was too high. I still haven't been able to fix it (as I don't have any tuning software), but my car just didn't want to adjust for my LTs.
