I havent had a chance to do a full write up. I will tomorrow. In the short, i am very happy with it. The auto switch allows you to adjust the flaps in the exhaust by rpm and throttle input. My system is the catless version. I should have solid results by tomorrow. The system fits perfectly, no issues at all. I dont have any pics of it fitted though.

Hi Guys
Ok, so ive had the exhaust fitted for a week now. And im very happy with it. On the dyno yesterday, the exhaust showed massive improvements over the stock headers. We were seeing gains of up to 60-80nm of torque through the lower end and mid range. We were also up 40-50rwhp through the lower end and mid range. How ever, up top power was leveling off. We believe this is due to not enough back pressure. The system i have fitted is the catless version. The only mufflers on the system is the ones fitted at the rear. Next week we will be fitting the cat section, and re dynoing. We also tuned the car with stock oem filters and bmc filters, the result, no difference maybe 1 rwkw if that.
The valves open, the car is very very loud. TOOOOO loud. The car now has a deeper note to it, which i like. With the valves closed, its quieter then stock but with a deep sound. The best setting to have the valve on is Automatic, which is controlled via throttle % and rpm.
The exhaust is a perfect fit with no fitting issues at all. The valves make some slight noise but nothing that would annoy you.
Hope that helps.

some pics of the exhaust are located in the other thread of Long Tube Headers. For prices call James at BPS Chiptek 07 3488 2911.
Alex, James also does my tuning, i do not know exactly the name of the software he uses.
Mods have been:
tune
2nd cat delete
filters
new exhaust now.
I should have updated figures next week and the week after i will be going to the track.

Nice.
Just a question for you guys that are modding, what do you do when you get logbook services? Obviously you arn't going to be removing an exhaust (like, 20h job lol).... just void it? that's it?
I am so tempted to get into this... but that's all thats putting me off. What if just something random happens....

No video clips as yet.
I have ordered a pair of Mickey Thompson Drag radials 245/40/18 - (26x9.5in equiv) and doing some modifications to the exhaust (i may have progress pics tonight, doing some changes to see if it makes a difference). I pick it up up tomorrow. Should be on the dyno Thursday? and Track next wednesday if all goes to plan.

does cargraphic sell a complete long tube set that deletes all the cats and bolts straight on?
price range for the entire set?
is this valve on all of them? how does the automatic valve thing work?
i would assume the sound with the valve fully opened would be similar to the sound of other LTH that are catless. i guess you would only know this if you've heard other ones on another car.

As super said, they are mid length. I have changed my collectors and extended the pipes from the slip joint. After tomorrow night i will write up differences on dyno and compare times with stock exhaust. Ive also tried a few other things. Results have varied but tomorrow night we will know the out come,
