Just installed my ARH LT's with catted H pipe, and i just wanted to tell every1 that these headers are the pinnacle of them all. The quality is amazing, the welds are spot on, even grinded off on the inside of the tubing, and the fitment is perfect, no rubbing issues whatsoever w stock engine mounts.

Damn these things are sexy, and the easier install with fitment, almost made me justify the price [8D]

very nice... how do they sound with the stingers?

I've been looking at getting the same set up. How long did the install take you? Did you use a lift, and where did you get them?

ARH's precision is phenomenal. congrats on your install

I came from having an off road h pipe so the level of loudness has toned down considerably. At idle is where the biggest change is between cats and no cats. The sound itself though is much more consistent and no more blatty that the off road h supplies. It still screams at WOT but it def isn't as loud as an o/r mid pipe.I believe it is the perfect loudness for a supercharger, which is down the road

memphis- Install took about 4 hours on a lift at my friends shop. We dropped the whole subframe and install was fairly easy. Purchased them at

Here are some questions for youacstone7: I'm curious about where the forward O2 sensor bung ison the ARH LTs, is it in the collector or in one of the primaries? Did you have your tune adjusted and are the O2 sensors turned on? Has it thrown any codes yet?

What's all involved in dropping the subframe? Also curious as to how much louder the LT's are with the GTA's vs stock.

howarmat

Its in the collector.

My rear 02s are turned off. Like howarmat said the holes are in the collectors and ARH provides 02 extenders. for the rear 02s I actually tightened down the sensors and stuffed them behind the heat shield [8D]

IMO Dropping the subframe should only be done on a lift. Remove the subframe and unhook steering rod, the engine must be supported before doing so.

Thanks for the info. I'm a little confused though. I intend to get longtubes with a catted H. I'm hoping this will pass emissions in PA, where they plug into the computer port to test.I'm assuming both the front and rear O2 sensors would need to be on to pass...true?

So I'm confused why you'd get catted H but turn the rear O2 off. If the cats aren't for emissions purposes...what are they for? Thanks in advance, I'm just looking to learn.
