I really wanna go with a set of Mac LTs and HiFlo Prochamber...Although my budget is pretty drained from gears/springs/wheels/tires - Oh well maybe in a month or two!

Anyone have clips of Mac LTs/Prochamber and Stingers?

 

Anything High Flow from MAC is Discontinued.... they're having a problem with their catalytic converter company.

If you give me a call... watch how much you'll save on MAC products

What would be the better buy,Mac LT's with Prochamber or ARH LT's with Catted H-Pipe?

 

ARH x 1000000000

There's nothing WRONG with the MAC's per say... they're still considered a "mid length" header. They are a mild steel, but they are coated and make decent power.

However the ARH's are top of the line T304 stainless and a true full length with formed collector, nicer 3/8" thick flanges, GREAT fitment, more power... 1000000 times nicer. It's all about the money....

You get what you pay for... just my personal opinion.

 

Yeah, ARH lt's seem like the way to go. Tillmanspeed,do you have the info about the cylinder heads yet for me and rafael?

 

I'll throw some info your way tomorrow. Sorry about the delay, this weekends car show and the first few days of the month threw me into a frenzy. My feet, hands, and head are still throbbing from today!!

I will PM you tomorrow my man!

The only cats the rear o2 sensors like are the the stock cats any other other hi-flo cats or o/r midpipe will require turning off the rear o2 sensors. The rear o2's are designed to measure the efficiency of the stock cats anything else just flows to well and makes the rear o2's think the cats aren't working properly. If you are getting that P0430 code then the rear o2's are still on.

 

I understand. I can wait for the info,since I am not going to buy them soon. Its always good to know about things ahead of time though.

 

Does that price include the MILs and O2 extenders like the Brenspeed package?

 

They're $20 bucks additional. It would bring it to $920.99 shipped.

The rear 02's do measure rear catalyst effeciency. Do you mean P0340 code? Just curious as I just replaced my alternator due to that code. It wasn't procuding enough power (amp's) and was running weak which in return through the code saying my passenger side cam sensor was messed up. I also have the rear 02's turned off in my tune due to my O/R H, but also had them turned off when I had my stock mid pipe.

I think that American Racing and Kooks are the best headers to go with. If your staying N/A, or don't plan on going past 500RWHP or so go with the Kooks. If not, go with the ARH's with larger primaries...

Just remember cheaper doesn't mean least expensive, and won't neccisarily get you the best results. If I were you I would talk to CR or consider Borla. CR offers the ARH LT's.
