The sound is deeper and more refined. Not at all overwhelming in the car but clearly there. The best part is in car from 3000-6500 rpm just sounds like the car should sound smooth deep and balanced.

 

That's exactly what I wanted to hear. Can't wait for a sound clip. Fabspeed is really onto something here... Whats the seat-of-the-pants difference in performance?

 

The seat of pants dyno is even more impressive. Between the better sound and notable hp difference the car is much more fun. I'll be interested to see if my lap times are any better this spring. As I told Nick from Fabspeed I would also imagine the car is getting better fuel economy but I just cant keep my foot out of it enough to actually find out.

 

Great to hear, sounds like it's an awesome mod

 

Are you going to the AM Owners Club Lime Rock Event on June 25th or any other events in the NE? I'll have my car sorted by then & hope to see you there.

 

I do most of my track time with COM SCC but am hopefully going to the AM event at LRP this year. Hope to see you there.

 

Awesome, very healthy gains up top. It smoothened out the power band too

 

Are you using stock muffler or something else? I removed my secondary cats & installed Quick Silver de-cat pipes.

 

What we realy need is a x pipe with 200 cel cats built in.

 

The early generation cars that only have one set of cats we did just that! 2005-2010 Vantage V8's have one set of cats that we removed and replaced with out HJS 200-cell cats followed by an X-Pipe.

Sport Cat X-pipe Exhaust System

For these newer Vantage V8's 2010+ there are 2 sets of cats, this x-pipe bypasses the redundant secondary set that is not monitored by O2 sensors.

 

Hey guys!

Good news the product is LAUNCHED thanks to John and I'm ready get a production run started if we can get a few guys in on it. I am having a special intro price for you guys on the forum, please PM or email me for me details if you're interested! Accurate dyno results and some sounds clips will be posted soon!!

Secondary Catbypass X-Pipe

 

Awesome,

Great price too. Would love to see some I house dynos as well just to see what you guys do on your I house dyno to compare to your other V8V dynos you have done in the exact same dyno (every dyno is obviously different)

Great job on finally bringing this to market!

 

I have a 2013 scheduled for next week getting the secondary catbypass AND a tune more photos, videos and power numbers coming your way soon!

 

See you next week Nick for my X-Pipe instal & ECU tune... Before and after dynos will be done for the 6Speed AM community. (apologies to Stuart)

 

Perfect opportunity!

If you could measure both separate and combined with the tune that would be awesome.

So glad you guys came out with this solution. It really is the perfect exhaust system for the later V8s
