Velocity AP Vantage 4.0TT secondary cat delete
Any advice or issues you ran into on the install? I just ordered these last night and plan to do the install myself. I have a lift in my garage, so that part will be covered.
Thank you.
Thank you.
I had the dealer install it. He said 2 hrs and its a tight fit. Certain exhaust components need to be loosened but i dont know which. Stu from velocity AP also told me to put exhaust paste on the one that looks like a socket connection. Good luck. Its worth it
Obviously they are bolted on with 3 bolts to the down pipes. The 3rd bolt (towards the top (closer to the engine) was a pain in the butt to reach. An extension is definitely needed, but 99% of car guys will have it. Other than that, follow a simple mechanical rule: do not tighten any of the bolts 100%, until they are all on. Tighten them all progressively so you can make sure the seal is perfect. I had to lift the car two more times to make adjustments because I heard a slight hissing noise (exhaust leak) from the coupler area (not the Bolton parts - you could tell because of the discoloration from the fumes existing). Just to be 100% sure, in the coupler areas, I also used RTV gasket sealer (the high temp red silicone for exhausts). This addressed the issue.
It’s an easy job. Back fires in track mode are much much louder (although I’m not a fan of backfiring cars).

Thank you for the replies. Installed them last week. No big deal. Sounds great! VelocityAP actually just posted a video of my car on the cat delete page. As a side note, if you watch the video, each pause is me switching between modes. Obviously starts in Sport, then I go through Sport+ and Track.

Looking to grow the 2019+ Vantage modding community - there’s not too much support out there for mods, which I’m surprised about considering it’s an AMG drivetrain.
I installed the secondary car delete pipes last week. Here's a video with cold start, revs, and acceleration runs.

Sounds amazing. Just enough crackle.
We are bringing out some new stuff very shortly - valved exhaust, primary downpipes. To add to the lowering springs, ECU tuning, secondary deletes and upgraded tail trims we already offer.

Wow those look very nice. I am confused. Are the tips the same opening size as stock? Do they require the rear bumper to be removed and the stock exhaust tips to be cut off and your new tips welded on?
Thank you for clarifying this. Sorry for so many questions.

The stock tips are just clamped onto the exhaust outlets so these are a direct replacement part which doesn't require any cutting or welding.
