What actual gains recorded from Belanger header and hi flow cats?

[Late Apex]

Bringing my 09 ACR in this week for the install of Belanger headers and hi flow cats with his cat back mufflers too. OEM computer so far. For those owners of a Gen 4 that have done this exact set up what increases on the dyno did you get with HP and torque over stock? Thanks.

Hey man couldn't tell you the exact amount for Balengers but I have dyno'd both American Racing a headers and M&M's on the gen 4.

Here's 1: stock with K&N, 2: Gen V intake, Mopar ECU, 3: American Racing Headers, stock cat back,and no cats

Bottom graph is going from American Racing Headers to M&M', 3 1/2 inch cat back and Mopar under drive pulley.

This is before (all stock) and after both Corsa catbacks. Changes: Belangers, cat delete, Mopar PCM. STD correction.

Not sure what the mods would worth without the Mopar PCM.





And just to whet your whistle, with the Gen V intake.

Thanks for the replies and info. I just got the ACR back today from Tomball and all I can say is WOW. The increase in HP and torque is breathtaking. The car plain hauls ass now. It is also very loud and reminds me of my old GTSR replica in sound. Stock computer and NO cel (so far) keep fingers crossed on that. Did the engine and trans mounts also which is a must IMO. Cant wait for the track now.

I have the same set up, PLUS the off road controller on my ACR. You really need to add the controller to complete the package. On the track the car becomes a complete Beast, it is so night and day difference you will not believe the performance!!

Agreed on the Mopar ECU.

While not 100% on topic, here is the GenV intake mod on a GenIV that starves in the upper RPM range with the stock computer.

Mark, you have to get the Mopar ECU. It really wakes the car up, even more than what you are experiencing now. Congrats on the Bellanger sound system.

Yes. I totally agree with that. I put the mopar controller on and it stopped the rpm hang when you lift on the accelerator.
Throttle response is better too. I got a updated flash from Winkles for it when in Charlotte.
