Firstly, I will be as unbiased as possible, I have run many configs of exhuast , HFC's / Test pipes on my vehicle both in a tuned for and bolt on state.
4 different TP and HFC variants prior to this test
Three different Y pipes
3 different intake set ups
2 full CBE's
Various tweaks for above via EM.
Today up for test are the MD ART pipes.
Mods at time of install.
Y pipe, K&N drop ins, stock ECU so purely a bolt on comparo.
I was going to wait till after xmas to do this but when I have car stuff waiting for install I gots to jump on it
I got the pics and idle video today, impressions below... I will get fly by / third party video during xmas break and update this thread accordingly, also will be going back to my local dyno to compare to previous runs.

So....
Buying experience.
Tony seems a very sound guy, easy to deal with, lots of time to respond to ?'s , straight up buying experience.
Delivery / Purchase
Spot on, super quick and very nicely packaged - good comms.
Pipe Quality
Very good, nicely done, great quality.
Speak for them selves
Comparo to stock units
6.5 lbs saving pair for pair, sorry scales stuck on Kg
Fitment
Spot on, no issues - clean, tidy install 45mins.
Video - idle and rev up
Driving impressions
So - Nitty gritty time, car had been idle for 2 weeks, fitted these, reset ECU and went for a spin.
Sound - Simular volume to HFC's, no massive rasp as usually associated with regular TP's, VQ 1800 rpm hiss is there but it was even with my stock cats. On full throttle very nice, got a good growl down low.
TRQ - Feels improved, especially around 3K, normally in my experience with TP's I have lost a little TRQ, these actually seemed to have picked up some for sure.
HP - Def makes a lot more power, RPM band is smoother and pulls a lot harder up top as expected.
Over all from first drive, based of learning ECU is...these are a great bolt on, the usuable power is great, the TRQ is very useful mid corner etc.
Going through the gears (VDC Off, I never have it on
means from 3K in first, plant the throttle, its fish tail till second, now instead of chirpping a little in second its a full on slide to redline, good fun for sure but shows a siginificant gain on my vehicle.
Like I stated , I will get motion video as the time over holidays permits, also will return to dyno for concrete numbers in new year.
Planning to get me an intake manifold from Tony in Jan to see how it likes it.
Hope you guys fimd this useful, any ? PM or post up.
