Good choice on getting a catted y - pipe with that LM1. It sounds like crap with a ORY and longtubes

Thanks guys it took me along time to get these headers I had my heart set on these headers for along time I mean I could of went with lower grade but that's not what I wanted I want great fitment and most powerful headers money can buy with out me having any problems later down the road I know they are expensive but you pay for what you get

You will be very pleased with your order. That's the same set up as me as far as ARH with high flow cats and their Y, along with the LM1. I was amazed how it took alot of the rasp and drone out. Even tho I always liked it anyway. The install was done in 30 degree while snowing under a open carport. I said if I'm doing it at this price then I'm doing it one time. Damn glad I did!

Yea I can't wait for mine did you feel a big difference with these headers like low end and or did you feel all the way around power and did you ever get it Dyno tuned sleeping hawk

It was one of those seat of the pants feeling! It felt like the power was so much better all the way around. I wish I had done a before and after dyno but never got the chance to compare it. Soon as I did the headers, I did the underdrive pulley new gears, and axles, then had John (mechanic) tune out codes and do the speed odometer and other things. Then later got it tuned by Frost.

I recently had Kooks headers and catted true duals put on mine. Everything sleepinghawk said is spot on. It really is a night and day difference plus it's going to sound great. ARH and Kooks are the two best headers you can go with on these cars, definitely a solid choice!

I installed my newly ordered ARH's just 2 weeks ago. My aplication is a stock LS6 long block, ls6 intake and now full bolt-on's thru an A4. My headers are 1 3/4 stepped to 1 7/8's. I had JBA shorty's with stock cat's and an SLP y-pipe thru a Magnaflow cat back. I have never driven nor rode in an LS1 4th gen so I can not say how they feel, but my LS6 powered car runs and pulled smooth like a freight train to 6500+ rpms. The delivery was smooth, controlled and very hard with a nice throaty sound and being 100% California legal. After the ARH install, I feel as though I lost responsiveness in the bottom end until 3500 rpm's. However, above that #, the power comes on hard and almost violent now in comparison to smooth. At cruising speeds around town 35-40 mph, everything is quieter, but hit it and the animal comes to life. The fit of the headers and catt'd y-pipe was like a glove with zero issue's. I had to remove nothing. I also do not yet have a tune and badly need one now.
