Velocity AP Vantage 4.0TT secondary cat delete
Just thought I would chime in having these installed last week. Apologies for the sub optimal sound clip I need to spend more time trying to capture the sound.... with flybys and bumper mounted mic.
Here goes.
1. Customer service. Among best in business and Ive done lots of mods. Stu underpromised and overdelivered. With lots of followup and prompt communication. I purchased out of stock and had them delivered in under 2 weeks
2. Quality. Perfect fit and finish, came with bolts and nice gaskets.
Pipes are labeled RHS and LHS with serial numbers. Nice touch
Stock cats, prob 400 cell
3. This is the best part..... sound. The car screams like an animal on WOT and the pops and bangs sound like the gun range. No joke. Ive done full exhaust systems before without this much improvement in tone and sound. It still maintains stock driveability but is a complete beast in sport + or track. Zero drone in any mode and I am super sensitive to resonance. Sounds Better than AMG with catless DP in my opinion. I will do a better video with side by side comparison to a stock vantage when weather is warmer. Here are a couple squirts in sport + mode. Its prob as loud as my gen 2 R8 was when you count the overrun. (Instagram vid clip attached)
4. Power. Cant tell as its winter outside and im spinning in 5th gear with all seasons on. As far as i can tell the car is more peppy with even less lag (if thats even possible on a hot V8) and it pulls hard consistently to redline with no dropoff. Will do some dragy pulls after weather warms up a bit. I would imagine improvement is marginal. I am also willing to dyno back to back with my friends stock vantage i bet there are some gains.
Honestly this is the best exhaust mod Ive ever done considering the price and result. Its a no brainer.

Thanks for the review! I am about to order the secondary down pipes + larger exhaust tips from VAP as well -- just waiting for Federal income the tax refund to come in! I am excited!

Handled flash is supposedly happening too

you own a new vantage and are getting a tax refund? what

The secondary catalysts are downstream from the O2 sensors so installing the secondary cat delete pipes should not throw any emissions faults that require the tune to defeat.
I don't really need additional power so I am holding off on the tune. If I change my mind I will probably go for primary down pipes + tune. Hopefully they will have cracked the software by then and have handheld tuners available (currently you have to send off your ECU for programming.)

It just means I gave Uncle Sam an interest free loan for a year!
I received a refund last year as well. I meant to increase my deductions but I forgot. Anyway, it's nice to get that money back and get some car mods.

Quick update. Ive got 400 miles on mine so far. I drove my friend’s stock 2020 vantage yesterday. With the cat deletes and high flow filters the throttle response is night and day. The torque hits much harder sooner and lasts a bit longer up top. Not to mention the sound difference. These are a no brainer.

Hello everyone...
I would like to purchase some high flow air filters. Does anyone know who is selling them and how much I should expect to pay? Is there a link to where to buy them? Thank you all for your help and response.

sounds good. Its a tight fit, a little more complex to install than a standard drop in filter.

Yes you are right. Tight mount but perfect fitment inside the airbox. Definitely makes a difference in sound volume and throttle response. I did this with the weistec blowoff valves and it makes the car alot more fun to drive.
