Ok guys I know everyone has been chomping at the bit to know more about these, so here we go! The wait was more than worth it! I just got done doing some test pulls using the V-box. Test pulls were performed on the exact same road going the same direction each time and launching at the same rpm as when I tested the Garrett and Vibrant intercooler cores. I have not done anything to the car since then except the 3" DP's. The car is an animal now and is having major traction issues in first gear which is why the 0-60 times aren't quite as impressive as the 0-100 times. Driving around town the engine power band is much improved, there is much more power on demand and barely any throttle is used to get going fast quickly. As far as exhaust note/tone there is a subtle difference, it sounds more throaty and deep but nothing that the wife will notice(my car is on completely stock ex other than DPs). Obviously with no cats, there will be a CEL that comes on as the PCM knows they are missing as that is the whole point of the rear o2 sensors. There are ways around this but Im not going to cover that as most of you already know what to do. With that said these are for off road/race use only!
I did 3 pulls so we can get an average of the gains. 0-60mph was 4.7,4.7, and 4.8 seconds. 0-100mph was 10.7, 10.8, and 10.9 seconds. That gives and average of 4.73 0-60 and 10.8 0-100! If you remember from the intercooler test the car ran 4.96 0-60 and 11.53 0-100 on average. So thats a gain of .23 seconds 0-60 and .73 seconds 0-100!!!!!!!!!!!
According to Wallace racing ET/Hp calculator a drop of 7 tenths in quarter mile is a ~70 hp gain!!!
So now onto the downpipes themselves, they are made of T304 stainless steel made in Canada and mandrel bent in the USA. A thick half inch stainlees steel 2 bolt flange is used where they mount to the turbos. 6" long stainless steel flex joints are used as well as 2 o2 sensor bungs located in in the factory location. Everything is hand TIG welded and back purged to get the strongest weld possible.
Price is going to be $1199 + shipping
Ceramic coating will be available in silver or black for additional charge.
Here is some pictures of the downpipes next to stock, installed and V-box results:
