Pardon me, do you have any Grey Poupon in that luxury sled?

 

Where is the ROFL smiley when you need it?!?!?!

😂😂😂

 

i just got my axleback installed. I have the first part of the video with stock exhaust and a decibel reader. After this weekend I should be able to get the second half of the video done which will show some cold starts and engine revs with the new exhaust.

 

That would be awesome! Thanks for doing this.

 

What are your guys' thoughts on blue exhaust tips on USB? Yay or nay?

edit: ah Fman already beat me to it, cool.

 

I would like blue tips for my LE.

 

That would look sick.

 

Loving my GThaus! I just need a personalized license plate now..

 

APEXi with burnt tips. Match the USB. 😁

 

Did you get the full cat-back? I have the axle back and trying to decide if I want to get the mid pipe.

 

Just axleback for now. I'm looking for a cheaper midpipe that will fit, tbh

 

You might have already responded, but how is the sound ? Is it as obnoxious as the catback?

 

Hey all, as promised, here’s a video with a decibel reader that shows stock exhaust and the GTHaus axleback differences.

I set up the car in an enclosed 2 car garage, the iPhone 12 is running the Decibel X app and is placed on the ground at 12” away from the center of the rear bumper.

I’ll eventually do interior sounds and flybys later on.

I will say, interior sounds are obviously louder but not obnoxious. It seems to peak at 6th gear but then goes quieter afterwards. So if you’re cruising, it’s very mild and only slightly louder than stock, even with exhaust valves open. When you WOT, you will hear it and it will sound glorious! This is what it should have sounded stock (imho).

Edit: For anyone wondering, if you turn the car off with the valves closed, they will stay closed. (If you have the remote switch) you can open the valves even if the car is turned off, but you can’t close them again until you turn the car on again.

 

Great video and even better info. Thanks for sharing with all of us. Very surprised that the stock exhaust was within 1 decibel of your axle back. Also good to know valves will stay closed when turned off.

 

It's a nice increase over stock for sure! Not sure how it is compared to the catback, definitely more tame.
Hmm, this doesn't work for me. I have mine tapped to a fuse that's only on in accessory mode so it doesn't constantly draw power. My valves will automatically open even when I shut the car off with it closed. I confirmed with GTHaus and that is the intended design (valves lose vacuum pressure since car is off). I'm not sure how yours stay closed.
