ARH 2" long tubes
Looking to see if anyone here has installed these on a 2010 LS3 Camaro. And whether you had any trouble fitting them?
I have 1 7/8ths long tubes now. Thinking about going bigger. Also I'm considering going with a Cat delete. Have high flows now but looks like ARH has a complete set up with open Cats. Looks like the ARH catless system has bungs for the O2 sensors. At least thats what the pictures show. Does anyone here know? Just wondering if I will need to weld them on myself, or if they come already installed? Thanks for any help! |

Unless you intend to go FI or a high HP stroker 2 inch headers are a waste of money .

Whats your definition of "high HP"?
I am doing a stroker build and want the max HP I can get from my naturally aspirated set up. |

They are worth 5-6 RWHP over 1 7/8 on a stock LS3 more with built motor.

Should get some gains from deleting the cats I would think. No???
They are pretty pricey. For the cost of these I could up grade my diff. Might be a smarter thing to do. If I could just win the lotto it would make this stuff so much easier

Cats actually are the law on the car equipped with them and removing them is illegal and a fine or 10000$ per occurance can be levied against a shop removing them and not replacing them. SO you may find some mainstream shops wont so you have too BTW and going to 2"
...sure if you have nothing but money to throw around and want more gas smell and more Rasp go ahead...But to go to 2" I would also be looking to install some $200 worth of Cats ...and 3" exhaust why not.... And no the Cats removal is worth Zilch they are high flow for headers and you have no obstruction really....Ever blow through one.... ? cats are no longer the old pellet of yesterday but rather more of a rod shape and not restrictive but more like a bunch of hollow tubes going in the direction of the exhaust flow...And I would suggest you read the Jannetty header test results thread on this page and under stand why 1 7/8 is chosen as the better all around header as if you look at the chart the torque actually is better from the 1 7/8 in the most useful range the 2-4k rpm range slightly due to design. I am sure you can sell the 1 7/8 headers on here ..Good Luck.

You are correct your money could be better spent elsewhere for making the car faster since you already have a great set of Headers. We offer completely built differentials on an exchange basis so you can swap out the diff in a couple hours minimizing down time and frustration of finding someone qualified to do a proper overhaul and gear set up. I have a 3.91, with billet caps, and Eaton Tru Trak all ready to ship. Ted.

On the header test, the 2" out performed all of the others, albeight the 1.875 were right behind. But 2" WILL make more overall power than 1.875. Is it worth it to you to spend 1200+ for just that small bit of power? That is something that YOU will have to decide. I know I sure as hell wouldn't. But that's just me........... LOL.

My 2'' Stainless Works went it smoothly(some small hammer massage on the fire isolator) and performs very well. Bought them 1000$ on sale.

I spent 400 bucks on a 2" Manzo ebay set of headers that ran the entire length of the car catless 3", ran them for a few years and went turbo. I have them sitting in the garage behind the door they are holding up well no rust and the welds look good.
Take advantage of 2" headers, do not kill yourself buying ridiculously marked up over priced headers. If i were you and already had 1 7/8th id be kicking myself ,like you are, for not going 2" LOL. Depending on what brand your 1 7/8th for switching up to a generic 2" will pocket you some money and add power. Engine masters on the tube do a good dyno spread break down header comparison on a SBC. Worth a beer and a watch. Last edited by bayarea408; 09-18-2017 at 11:10 PM. |

You will not loose any horsepower, only see gains throughout the entire band. Many tests have been done and have had the same results. We have done many at the shop on a mustang dyno and have seen no losses.
