Exhaust train modifications... Ques?
Okay, I've got three choices apparently.
Bramford
Velocity
Quicksilver
I have a 2015 Vantage V8S. I like the sound when I hit the sport button.
Other than reduction of weight, what is going to be my reason for selecting either one of the three? This is not a question about which "one" is better since apparently they all provide a fine product.
Apparently, I can get more db's with a quicksilver exhaust. However, I find the sound level when I engage the sport button is "loud enough".
Are we talking HP here, or simply noise volume? Also, if I replace exhaust manifolds (headers), cats, will I need to replace the rear muffler too for maximum HP. Also what will be my HP gains without the ECU remap?
Remember this is not about Bramford vs. Quicksilver vs Velocity (i.e., which one is better), so please not make it about that I'd just like to know what each one can offer to a Vantage V8S and I'll make a decision from there.
Expecting to hear from Stuart and the guys from Bramford, here.

Thanks for posting, and hope the Porterfields worked out for you in curing some dust issues.
There's not much to choose from between one supplier and another in terms of HP increases, for the most part as you've identified. A couple of specific questions you asked:
- Replacing the rear muffler does little to nothing in terms of HP increases. It is really about weight reduction and achieving the sound level you want, whether increasing that or fine tuning it to your needs.
- If you do the full shooting match (headers, cats, ecu, filters) you should see 50BHP, or just shy of.
- Without the ECU tune you should see 30-35BHP, however I would not recommend doing headers & cats with out doing an ECU Tune for three main reasons (leaving aside the HP increases.)
- Changing to a single pair of motorsport cats can produce transient CEL's for catalyst efficiency. Not all the time, but in particular in cold weather when they don't heat cycle as quickly, or when doing a lot of short trips.
- On the later MY cars (2011-on) because the O2 sensors are relocated from the manifold back to the catalyst section in the transmission tunnel, further adjustment to the ECU settings is required for seamless and DTC-free integration. The physical movement of the O2 sensors downstream changes the response rate to fuel trim changes in closed loop. Similar to the Catalyst efficiency codes, the 'Slow Response' error codes will not trigger 100% of the time, as the condition is marginal but they will inevitably report this error state at some point. For proper integration, you need the ECU settings altered to allow the car to run as though it left the factory with these exhaust mods.
- A VelocityAP-specific reason: Insurance. Every time we write an ECU tune, it includes £2,000,000 GBP of insurance coverage on your engine, including public liability.
- Sound Level on the rear exhaust portion: One person's idea of loud is another's idea of too quiet. One thing is for sure; when you change headers/cats the sound level goes up substantially. There are a few options here, all of which we have successfully executed for customers:
- Exhaust Valve Remapping: As part of the tuning process, we can alter the RPM's at which the exhaust valves open & close. Sometimes if we simply push that level upwards, people find they can operate in stealth mode with valves closed on the OEM back box up to say 4500RPM and by staying below this, the exhaust note is muted enough to keep things classy.
- Custom-Sound Level Conventional Silencers: Our X-Pipe silencers in particular offer a very broad range of sound across a fixed (non-valved) level. In some cases we have produced silencers which are quieter than our 'Touring' sound exhausts, in order to bring the overall level back down to an acceptable standard for each customer.
- Custom-Sound Level Valved Silencers: In cases where people want 'mild to wild' type scenarios, we can again create valved systems, which are a little more expensive but which offer both quiet & loud performance and enable the use of Sport Button control or remote control/override switches. VelocityAP actually built a custom silencer for the owner of the DC Dealership, for his personal car. The brief was that he wanted the exhaust note to be at exactly the same level as an entirely OEM exhaust setup, when operating in conjunction with our headers/cats/tune etc. We produced a system which was actually MUCH quieter overall than the OEM exhaust both when valves opened and closed, so that you wouldn't even know from listening that the car was running a non-standard exhaust.
In addition to providing the ECU tuning to support the physical parts, we also work with a number of main dealers & independents, which means you don't have to ship your car thousands of miles away, you can receive great products & service close to home.
Hope this Helps

Great info Stuart. I've got a clearer picture of what's at hand here.
Yes, the Porterfields are great. They greatly reduced the level of brake dust.
I've still got your notes from prior conversations about opening up the exhaust train. I'll do some "man math" and decide what to do from there.

Like new Q/S S/S
I have a 10K mile (like new, bright and clean) Quicksilver SuperSport for sale. Light weight and the best sounds you can imagine.
A bargain, you pay the shipping from Dearborn, MI. Interested? Send me a PM.

Did you get that X-Pipe system fitted then?

Our latest development is an N430 system which is supersport sound level and offers a huge weight reduction and will fit your car http://www.quicksilverexhausts.com/A...ctbulletin.htm
For further weight reduction we have a titanium silencer version http://www.quicksilverexhausts.com/A...ctbulletin.htm
For Ultimate weight saving we have a fully titanium version
http://www.quicksilverexhausts.com/A...ctbulletin.htm
Our SuperSport Plus system provides the greatest sound levels compared to the above http://www.quicksilverexhausts.com/A...ctbulletin.htm
If its a daily drive you may prefer our Sport option with our cat deletes (which also fit all the above systems) http://www.quicksilverexhausts.com/A...ctbulletin.htm
Cat deletes http://www.quicksilverexhausts.com/A...ctbulletin.htm
All of the above are kept in stock ready to despatch.
If its ultimate performance you are looking for the our GT4 system and manifolds will provide that for you, these were designed for the GT4 race series and provide significant weight reduction and increase in BHP and Torque http://www.quicksilverexhausts.com/A...ctbulletin.htm (This one is incredibly loud!)
