I am so jealous of you Gen 4 guys. All you have to do is add filters, full exhaust, and a mopar PCM to see 600+ rwhp
Having heard them side by side which would you say has a deeper tone??? I am not a fan of the higher pitch of the corsa exhaust.
And now I just don't know which way to go. Guess I will wait till I can here the BBG exhaust in person before I pull the trigger.
I have a new ACR and highly considering the full Belanger set up including their headers, cats, and exhaust plus the Mopar PCM (installed by my Viper tech who has done many of them). For those of you who HAVE this complete set up installed on your Gen 4, are there any negative sides that you have personally experienced such as CEL, rough running, or anything else I might need to know. Im aware its expensive and loud and thats fine but dont want issues down the road. Whats your personal results, good or bad? Thanks in advance.
wow
I heard Viper X's Belanger headers to Corsa and it sounded good and "racey" but not loud enough and not enough "burble" to me. I like that old muscle car sound that makes the dishes in the kitchen shake when you pull into the garage
guys here is mho and personal experience:
too bought the acrx headers. it was a mistake. the belanger's are a million times better quality, better craftsmanship, run cooler, fit RIGHT, and install way easier and make the same power.
in fact the 2 highest hp gen 4 cars are running belangers.
i made a knee **** reaction and it was a mistake.
i had 2 customer cars and mine here to put headers on.(an o8 and a '10) and installed headers on all. one got belanger, the other got acr-x headers.
they both made the same power before on our dyno and after (the belangers made a bit more torque)
however the acr-arh headers have warped flanges, are mig welded, and were a super PIA to install. i will never again recommend anyone use them. even the Blenager 02 sensor wire extensions and hardware are a zillion times better quality.
belanger even puts secondary heat shields on the cats and collectors.
i called arh about the warped flanges, 3 times. no one seemed to care..........
you could just look at them and see they were warped a bunch. on a straight edge they were both warped over 1/2" to the right, both headers the same way which shows me its a consistant problem with heat draw and ARH jig fixtures. i had 2 sets both the same way.
i had to port match the acr-arh headers where they bolt together and i couldnt do anything about the flanges-it will probably be a constant retorque on the flanges to keep them sealed. i am not even going to go into how much of a PIA it is to bolt together the mid sections of the ARH headers. if they would have used a bit more thought and offset the the 2 out most holes it wouldnt take 30 minutes to tighten 2 bolts..........or make them a 5-1 slip fit merge like B&B or hennesy
checked the Belangers and they are laser straight, and perfect fit everywhere..
if i wanted the pain and agony of pulling the arh headers off i would sell them and install the belangers in their place.
i have a set of GEN 4 Belangers $ 2700 shipped to you, and that includes belangers high flo cats with heat shields.
its all good now and irrelevant. i bolted the headers down to a steel table and heat cycled the flange with a torch. then went back and lightly machined the flange.Holy crap, your flanges were out 1/2"?? That's not warped, thats bent to hell!

this type of problem is common with mass produced mig welded headers.
i havent had to install old school headers like the ARH in years. after putting on B&B, burns and bellanger for the past couple of years, i didnt think anyone made stuff like this for high end cars like the Viper. ARH headers are what you expect from Summit or Jegs for a 78 camaro...........
for what they cost i couldnt believe that they were mig welded and such mediocre quality.
the insides were still full of metal grit and cut off wheel grindings.
i spent a good 3-4 hours fixing them and then cleaning them before i could bolt them on. since then i have made heat shields to protect the lines, ac box and wiring on both sides. the end result is there, but not with out lot of work.
i need to post pics of my B&B headers on my gen 2 and gen 3..they are works of art.
hell even the stainless works on my ford raptor and dyna techs on my challenger are pretty and tig welded, with better collectors.
we sell and install racing exhaust everyday for motorcycles. the quality of any one of those headers would run circles around the ARH headers........in fact if a company offered a product constructed like the ARH it would be banished from the market.
my point is the ARH is way over priced for what you get........
George, first off you need to chill out. how i handle my supplier problems is my concern, not yours. i simply stated the facts about a manufactor build flaw.
installation doesn’t have a damn thing to do with the flanges originally being warped from ARH.
fact: the flanges on the ARH headers were warped on 2 sets of headers
fact: i own and operate a modern CNC machine and fabrication shop. yes we do tig welding and have done our own headers before. so i do know what i am doing and talking about- we also have our own tuning center as well
fact : i called and asked to speak with Nick 3 times, he was busy. i was told " oh that’s common, just bolt em on...." my reply, " no that’s not common, i have been doing this for 25 years. this isn’t common.
fact: is it fixable. yes, should i have to? answer: no
Fact: i run 3 business and i am hands on in all of them. if i can’t get a manufacture to step up and get it fixed quick. then i do it myself, and i do whatever i have to get the job done for my customer. i only have so much time in the day to get stuff done. and ******** at somebody over the phone aint getting it done
that’s why i have my own CNC machine and fab shop. I’ll just do it my damn self
fact: A&C performance had the same issue with ARH. it’s a common thing with high heat-mig welded mass produced headers, that have thinner flange thickness such as ARH. if they tig welded the flange, we wouldn’t be having this post.
Fact: God Bless Toddy, but he didn’t build or design the headers, this aint got nothing to do with him.
fact: if you knew anything about tig welding-exhaust system fabrication, and have installed hundreds of header systems like i have: then you might not stick your foot into your mouth.
fact: will anybody who bought ARH headers regret it. no, they will be fine.
fact: the overall mechanics of the ARH system is a decent one. it’s the same one the Edelbrock had over a decade ago. it wasn’t anything new, bolting together a header in the middle is the easiest way to manufacture it.
ARH, just duplicated what Edelbrock did and made it fit the new head; i just don’t care for the craftsman ship, mig welding, warped flanges, and collector design.
fact: is ARH headers over priced? heck yes, when you can look at a beautiful TIG welded and polished B&B system for less money, and get a superior collector design and a system that slides together in half the time
.
if you like ARH headers, then by all means run out and get a pair. the ones i installed it will be the last ones i recommend to anyone. i wasn’t here to start a war, just sharing my personal experience like everyone else.
No to be negative (since I'd like very much to do and am always considering these mods), but since you're asking, the Mopar PCM will also eliminate all exhaust burble. Relatively minor concern, but I spend way too much time continually talking myself out of this mod and I'm eventually going to loose the argument (with myself).
I like how SRT just came in the thread and set the record straight.

maybe ARH is the best because they gave the lowest bid and they were the only ones who wanted to crank out a whopping 50 sets............
^^^^this^^^^
$1800 difference between what we pay per set, and what Dodge paid.

Wow! Crazy Thread.
I had to chime in here.
Gary at X-metal, for as long as I have ever dealt with him, has been golden to me.
Nick at American racing from the day I met him has been golden to me.
I would do anything for both of these guys.
I have to say that I am not sure what happened then on these headers that Gary Received. I'd have to say maybe Nick was ill or something if he didn't get back to you. Heck I know we all get overwhelmed , but when I have an issue, I can reach Nick at 9pm and he always rectifies it period. No questions asked, IF there is a problem which is very rare.
I have had some issues where only a **** was in the wrong location and when I call Nick, he overnights me a new set, period.
I have to say that I've run all kinds of headers. Even had some Belangers that made no additional power on a Gen4 when I tested it. And from the beginning, I personally love the ARH headers quality and fit...AND Nick. I would use Gary at X Metal for anything! The guy is awesome and delivers great products. AND builds some BAD ASS BIG BORE SPORT BIKES on top of Viper work!
It's too bad things ended this way between two great guys that really bend over backwards for people.
I'll still say that when Headers are called for, I take Nick and American Racing over Belanger any day.
And if I have to say with Nick and Gary. Man, how bout you guys fly out here to me and I'll buy dinner and patch this up. You guys seriously are both so straight up and honest you'd want to deal with eachother!
