ACR exhaust mod

[commandomatt]

Hi all,

Thinking about installing a new header / exhaust system on my 2010 ACR.

I dont even have the car yet (wont be 'home' until January) but want to start thinking about it.

I know there has been tons of exhaust threads on the 'other site' but would like to start fresh here. I have Corsa's on my 06 but no headers. Its sounds pretty good but I want more.

Goal:

- Have a powerful and loud enough system that will turn some heads yet not be so obnoxious that I cant take the car for a longer drive
- Make some usable power
- Not set of a bunch of codes and have to mess with that
- Absolutely love the 'Pops' and want to retain that if possible

Give me some ideas. Also include prices I can expect. I may have it installed before the car leaves the dealership

Thanks

Matt

You will get tons of ideas on this and it depends on how much you want to spend and possibly deal with CEL issues too. Hope there is a good Viper tech at your dealer too for the install. On my 09 ACR I just did the Belanger cat back and has popping with a better sound than Corsa IMO and NO cel issues. For the most HP gains and loudness go with the complete Belanger headers and exhaust along with the Mopar PCM. Jon at PartsRack can hook you up on any of these and also send to your dealer for install. Cat back only around 1200 installed. Plan to spend around 3800 for the complete system plus another 1200 or so for the PCM. Hi flow cats is another add option. Its all $$$$$

[ACRucrazy]

ACR-X headers, corsa, spark plug non foulers after the cats (stock pcm) to retain the pops but Mopar PCM would be better IMO and a ported stock lower intake. Should be 600 rwhp give or take.

[commandomatt]

So, I will loose the Decel Pop when going to a Mopar PCM, yet there may be enough of an improvement that its worth going that route....does that sounds about right ?

I want to stay under 5K total

Dont want to get into any engine work at this time

BTW...if it makes any difference, I dont live in a place where the car has to pass any type of emissions testing.

American racing headers and a single cat delete sound amazing.

Bruce,

You got a PM

[BlknBlu]

So do you

Bruce

[commandomatt]

Ok, so I got 3 replies....and 3 different headers. This is getting harder than I was hoping for.

- Belanger
- ACR-X
- American Racing

Any negative feedback on the 3 above so I can eliminate one ?

Thanks

Matt

[BlknBlu]

ACR-X and American racing are one in the same. Those are your 2 best options, but that is just headers, You still need to decide on muffler choices and Cats/no cats or aftermarket cats. A lot of combinations to work with.

take your time

[RedTanRT/10]

Headers and a cat back will be much louder than your '06 with a corsa

If your adding headers for more hp/trq suggest the venom ECU, but the decal popping goes away

Both header choices are good, advantages to both, Belanger more lower, ARH dyno champ.

Headers will create a CEL, it's when not if, venom ecu eliminates CEL

If your looking to balance sound and power it would be a good idea to find someone local and hear their viper at idle as well as under load. Good luck, Mike

[commandomatt]

I like the lower, deeper sound. If that means Belanger, so be it.

I was going to take the approach of decide on the best header, than based on that decide on what I use as far as mufflers/cats

There is no one close to me. A Gen II 50 miles away but other than that, 5-6 hours. So it would be hard to listen to something in person.

I agree with Bruce not to rush this. At the same time, the car is in a better place to get worked on now as opposed to when its shipped this way

Installing ACRX headers at the moment, but switching to the new M&M 1 7/8 primary tri y's as soon as they can get me a set made, no cats and the new M&M 3 1/2 inch catback. Should make a shit ton of power.

Not sure what your skill level is but I install them myself so I know they are done right, and I can heat shield anything extra that I see fit.

I am also running the Mopar ECU.

Ill have to post up a video of my setup. Belanger headers, hi flow cats, and cat back exhaust. It sounds really good.

Do it...would like to hear it

So is this a brand new system or just new for Gen IV ?

Sounds interesting as long as its not to obnoxious on longer rides

When do you think you will have yours ?

Matt

[FLATOUT]

Should be the same system design just with larger primaries. Should help people take better advantage of ported gen IV/gen V manifolds and ported heads.

I would think I am a month away from having them maybe two. They have one set in use working great and I'll get them on the dyno as soon as I get them on my car. I'm not looking for something extremely loud either so I'll let you know how it goes.

Ask and you sahll receive...

First video is at start up...


This is after the car has been at idle for about five minutes...



Again...full Belanger exhaust. Headers, high flow cats, and catback exhaust.

[commandomatt]

Sapphire,

That sounds good. Thanks for posting.

At this time I am going to step back and see how Flatout does with the new, larger system. That may set me up better for additional mods later on.

No problem. Good luck!

60+ sets of the Belanger headers and Corsa catbacks installed here, Belanger equipped car will walk a AR car all day long, I would suggest the Mopar PCM though.

[ACRucrazy]

Does anyone have a dyno graph comparing the ACR-X headers and Belanger headers on the same car?
I have yet to see one.

I find this hard to believe. Is the area under the curve that much better with the Belanger? Do you have dyno overlays comparing the two?

While I have never had any dealings with Mark personally I would trust his word.

I do not have any sheets here and I can tell you that on the dyno the ACRX header looks better, but on the road a Belanger car will always be faster, I have even had that confirmed by a guy very close to the American Racing header project...

While I have never had any dealings with Mark personally I would trust his word.

Thank you, nobody is ever always right, I know that, so everyone "could be right". I will never claim to know it all, I do believe in the Belanger products though and offer them without reservation to my customers.

I have to side with Jorgensen (again)


The 'comparo' of Belanger and AR is not as long, since Belanger began making Viper headers in 1992, and AR is a relative latecomer. Some Belanger advantages:

Belanger has Tri-Y easy install +Velocity cone collectors for more Torque thru the full RPM band.

Power band starts LOW, not HIGHer in RPM range. More pull from the line. More mid-range torque. Wins at the STRIP.

Metals Matter. Stainless runs 220f hotter than Alumanized steel. Belanger is alumanized. Stainless = high picth tone, Aluminized = deep/muscle tone, was Used in musclecars of 60s-70s.

Belanger INCLUDES Jet-Hot ceramic coating. Extra cost @ AR and Coated Stainless still remains 200f hotter than Belanger!

FACT: ACR-X header was chosen for 3 reasons: and none of those reasons were "we want the best"

1) Cheaper by many hundred$;

2) Fast build commitment of 50 sets. PERIOD.

3) Spec-Race Series; All cars 'the same handicap on everything.'

Purpose built race cars like ACR-X dont have much that is vulnerable to HEAT. All was REMOVED ! Street cars do: CHOOSE BELANGER [or MM ] for this ALONE !!
