Valve exhaust systems is need or not?
- Thread starter IconicSTallion
- Start date
I have a set of valvetronic mufflers installed on my ST which give me the flexibility to have a quiet stock sound or a straight piped exhaust sound. These are the same mufflers that Savage Garage installed on their ST
This link is to a clip of what my exhaust sounds like in loud then quiet and back to loud.
I removed the resonator and installed an x-pipe as well and when quiet my wife didn’t even notice that I changed the exhaust. The only drawback to these mufflers in my opinion is when on quiet under wide open throttle they make a sound that sounds like a blower motor on high inside the vehicle. I don’t know if it sounds that same way outside the vehicle.

Why stop there? Dual 3.5" custom exhaust would be even better, right? Especially with double X pipe. If you want to spend 2 grand to gain no horsepower, you need to look at Ersatz Bros tuning products here:

I added a set of tips, due to the limited space I found a set of Porsche 997.2 carrera tips that fit perfectly.
I installed the vacuum line and power myself. That took about 45 minutes I fidgeted with how to run the line through the pressure vent in the rear quarter until it dawned on me to use a nut a piece of fishing line and gravity to find a path for the hose. For power I just used the power outlet in the cargo area. It’s currently plugged in there but I plan on splicing I to that line and having the plug installed behind the panel to keep the cargo plug open to use if needed.

Overall I’m really happy, in quiet mode it’s almost unnoticeable that I have a different exhaust but when I want to open it up I can. I think that noise is just the turbulence caused by how the exhaust flows through the bend in the muffler at the exit which only occurs at WOT so not too often in everyday driving scenarios.
I did a similar thing if not the same if I read this thread correctly.
I installed a Borla Atak catback exhaust.
I removed the mid resonator and replaced with a custom X-pipe.
The sound decimal level went up from 8 to 10 or 11 however the tone of the exhaust also changed and sounds distorted on WOT.
When you rev it in park it sounds almost v8'ish or very close. When you drive at a reasonable speed with a level throttle sounds good.
When you get on it on the WOT it just sounds like a whole bunch of distorted noise.
I asked my shop if we could put a resonator in the x-pipe to try and refine the exhaust tone but they said it wont do anything.
I also get a lot of drone obviously without the resonator.
If anyone knows how to work with what I have which is Bora Atak/x-pipe to increase the decimal from 8 to 10 but not gain much in distortion, I'd be forever grateful..
This is probably everyone's dilemma lol. How to increase sound/tone with limited drone/distortion.

You might be able to replace your midpipe section with the one from the MRT Interceptor. It has a helmholtz resonator built into the mid pipe. Take a look:
