Back in February 3 months before I had my car I decided I wanted LT Headers for my car, after reading several reviews and deciding on what my goal was for the car I decided on the ARH Long Tubes with 1 3/4 primaries. Very huge thanks to Weapon X who gave me an outstanding deal on them, I highly recommend you use them for ARH headers.

I sent mine off to a coater and had the insides done with 2000 degree race coating and the outside done in 1200 degree Chromakote. Judging from the feedback of the installer he was quite pleased with the fitment of the ARH headers and said they installed like an OEM piece. Actually the OEM piece looked much cheaper than these.

He ran into a couple of issues installing them, first off the O2 sensors were stuck in the pipes and ended up stripping, make sure you can find a replacement sensor there are not many around. The other issue was the ARH gaskets which he threw away and re-used the stock ones. He felt the quality of these were not good and would result in a quick failure.

While the car was being done I also had the rear pipes wrapped by the transmission and rear dif to keep heat transfer to a minimum. I will see what difference this makes on the track. Overall no issues no noise and no leaks.

Impressions: They said to me this car is no louder than it was, then I said do you have it in Sport mode....what is sport mode? I got in the car and flipped the dial. HOLY CRAP!!! Talk about going from mild to wild you do it this simply. This shop is a race shop for Porsche's and Tudor Sports Car Challenge cars. About 6 guys came over and said what in the hell was that.....the Vette they all said....

This car is insanely loud with the ARH headers and NPP exhaust and the sound is simply intoxicating. Out for a test drive, I got a tune from Vengance racing and I wanted to give it a few blasts. All I can say is the headers made a huge difference in the low end torque and the pull up top. The difference is very noticeable. I thought my race exhausts were loud on my M3 but these are simply insane. The car sounds amazing and the power is intoxicating. What I love about the NPP is you can go to very tame if you need too or you can blow out windows with the baffles open.

I get a dyno and WOT tune on Wed. I'll post results it will be on a Mustang Dyno so the numbers will probably be lower.

 

 

Not even an honorable mention huh... lol. Glad you're liking them.

 

You got me wanting a set for the C7. Got to get a few other ends sewn up first! Nice! I know they would add under the curve with my Blower kit!

 

My ARH long tubes go on next week

Going to be interesting because there are no local tuners where I am located...

The installer is going to leverage an individual who runs an outfit called "Livernois Motorsport) to remote tune the vehicle. Never previously heard of the company or their rep so it will be a bit of a roll of the dice.

 

Ben I owe you a huge thanks. To all Weapon X was awesome and the best price I found on my set up.

 

I bought HP Tuners, which is what I would recommend. It costs $500 and then Mike at Vengance can tune the car for you. It is very simple, I loaded my program on before going to the shop. Then he can data log your car and make tweaks. You don't get a canned tuned that way. I also don't live anywhere near a tuner.

I think this is perhaps the most important part about adding mods to a Corvette LT1, get the right tuner who knows what their doing. I wouldn't compromise in this regard.

 

Livernois is one of the premier shops in the country, so you should be in good hands.

 

This is awesome. Just what I wanted to hear to lock in my header choice. I also have NPP exhaust, but mine was added to a non NPP base C7 so I will be blowing out windows until I can get a mild to wild working..

 

Livernois is a one of the top motorsports shops in the country. They are excellent. Nothing to worry about.

 

Leadville thank you for sharing your thoughts. We really appreciate you choosing ARH. Enjoy the system!

Nick

 

So Ben, are you a speed reader? Maybe you should re-read the first paragraph "leadville1" posted. Seriously though, the 1 3/4" primaries sound small compared to the 1 7/8" and 2" so many are discussing. Do the 1 3/4" flow well enough for up to 500+ hp? Are the 1 7/8" or 2" over kill for "leadville1s" state of tune?

 

It's called the edit button...

 

haha I'm not the only speed reader... it happens

Just joking with Jim, he's already shared his weaponX experience!

 

Hi Nick,
Are you going to have headers installs at Carlisle this year? Count me in!

 

I went back and Edited, Ben is awesome to do business with.

 

I am not going to say anything negative about any tuner, but let me just say that I did talk to them about tuning my car with my set up. Their tool is not designed like HP tuners is, and they also have not tuned a car with ARH headers and and an AFE intake. If your going to be making an investment in a tuning tool, I would make that investment in one that can give you access to more which the HP tuners does. I also would consider how much experience they have tuning this particular car. Let me just say I would encourage you to ask tough questions before you make your choice and be confident in the person doing the tuning.

I have complete confidence in Mike and the time I spent talking with tuners was time well spent.

 

ok, it's wednesday.... where is the dyno graph.. lol sorry I'm just excited to hear the car, and numbers.

 

Dyno got postponed until tomorrow, Mike was in New Orleans. We got the part throttle done today and the dyno is at 10am tomorrow to dial in the WOT and then off to Road America for a weekend on the track.

The car is just plain wicked loud, a neighbor a block away said he woke up from his nap when I rev'd my car....seriously a loud car with NPP and Headers.

 

Is it tomorrow yet?
