What s the best exhaust setup for the gev v gts

[jaxtk]

Not to familiar with the arrow pcm, is there a way to get the cliffnote version explained to me? Price, purpose, ease of install. I don’t think the warranty will be an issue for me at the dealership.

Think again, kiss your warranty good by.

[ForTehNguyen]

depends on the dealer. To me the car has enough power and sound, not worth risking warranty for a little extra power

That’s impressive for the older model. I had similar temp issues with with my z06 on the track and did a couple little tricks to cool it down. Do you have an upgraded radiator? I also like to use redline coolant water wetter. It has always dropped my coolant temps down on the track.

I never tried an upgraded radiator but someone else on here did (Karl, I think). Didn't really help. He tried various things (removing hood vents, removing weatherstrip at back of hood, Viper engine covers, etc.) to get the car to cool down, not much helped though. He also changed out the water pump with one that had closer tolerances (he got it from Arrow). I believe the water pump helped. Dick Winkles (engine designer) said car is ok up to about 250 or 255 coolant but the PCM will start pulling timing below that number. Plus the dash starts flashing a red warning at 240 which is a bit disconcerting.

There are some threads on here about cooling that are worth reading. Here's one:

Car feels great, no doubt about that, I just want some more out of it. It’s just in my nature and my obsession to modify my vehicles. Lol.

I had the Arrow controller on my 2016 ACR w/ belanger headers/hi flow and exhaust. I had high temp issues at multiple tracks, car even shut down a pit out. . On my 2017 ACR I only did the headers cats and exhaust and I have had no high temps. Same basic car, set up , and tracks of similar temps. Only difference was the Arrow controller. Other Illinois club members with the controller have experienced same high heat temps. Its my understanding that if your motor goes and there is any indication that the controllers had been swapped you kiss warranty good bye. FCA can verify somehow by the mileage in the computer if the controller had been swapped. I don't know how much HP the controller made but the throttle response was much improved.

A friend in a bone stock 2014 GTS was at the track the same day I was there in my 2015 TA 2.0. I had full Bellanger headers and exhaust with the Arrow controller. His car was just as it came from the factory. We were running similar lap times. His temps were 239 mine were 241. No appreciable difference with or without the Arrow controller. I did multiple tests - with Arrow controller, without Arrow controller, without under drive pulley, with under drive pulley. No statistical difference.

Re warranty, while FCA did originally deny engine claims for three cars with the Arrow controller they eventually reversed that decision as examination of the bearings that failed showed they failed due to debris not detonation or something that could have been caused by the PCM. There are several threads on this site concerning this.

The basic problem with the Gen 5 re cooling is the air inlet in the front bumper is too small and the engine compartment is too tight as compared to a Gen 4.

sounds like I will be going with a custom tune then, lol. hp tuners.

I will start looking into cooling mods and see if I can make something with the 3d printer to better direct airflow under the hood

[Scott_in_fl]

There looks to be significant opportunity to pull air into the engine compartment from underneath the car. The underbody has a panel in front of the engine that could potentially be ported to allow air to be driven into the engine compartment. The real issue may be how to get the air back out (preferably someplace up at hood level and near the rear of the engine compartment so that you have some lateral flow up and out of the car just before the windshield).

Thank you. Does anyone have videos of the different manufacturers headers and exhaust, and how they sound.

Here is my car with Belanger longtubes, hi-flow cats, showing off the difference between Corsa and Belanger catback.

I believe full Belanger is the best absolute tone for Vipers, period. Just my opinion.

I would take those blanket statements with a grain of salt. TONS of guys track with Arrow controllers without issue, so there could be a lot more to it than just ecu.

Great video, I appreciate it. Sounds good.

Arrow PCM is like $1600-1800 (?) i believe, it will disable the primary O2 sensors so you can run the headers without a CEL and other tweaks to the programming. I didnt want to risk powertrain warranty, gasoline smell, or not being able to pass emissions so I didnt go that route.

Arrow PCM is $1100~$1200 and disables the rear o2 sensors and not the fronts/primary's. Also if anybody is curious about the uncatted gasoline smell; it really doesn't bother me much and I can hardly smell it. There is not an abundance of exhaust that comes into the cabin with the windows down or up in my experience. My girlfriend didn't even notice the smell and she hardly tolerates anything car related (working on fixing that lol). Even when I do smell the uncatted exhaust, it smells like race fuel/C16 and isn't actually too bad haha.

Thank you, this is really good to know. I had no idea it was that bad.i will do this at the same time as the full exhaust install.

As for the heat issues, I didn't want to play around. I have the full uncatted ARH setup with all the drone. I got every inch of the exhaust ceramic coated inside and out (Except the inside of the mufflers), and I wrapped every inch of the exhaust with DEI titanium wrap. Underhood temps are noticeably lower when I open the hood, nothing has melted, and the side sills hardly even get warm. Very glad I coated and wrapped everything because the heat isn't an issue at all.

Does the Corsa just sound like a louder version of the stock exhaust to you? That's the impression I get from many of the Corsa vids. The Belanger sounds very different from stock though.

Sounds very similar imo

Eddieg, I sent you a PM with detailed information on the subject and my findings with a header swap.

Will I be able to achieve the same power numbers with hp tuners?

That's exactly how I would describe it.

Corsa is very loud past 4k, but is very restrained and drone free below that. Belanger is deep and "droney" all throughout the rev range. I didn't particularly like the corsa "dump truck" idle and hollow low rpm sound.
