2 different products, 2 different approaches, but Australian made.
I have the BM DP on my GENII. As for power agains and better engine response, I can't say enough. But I am still having trouble with CEL's (check engine light) which has got to do with how the car is reading the efficiency of what were 2 cats. The DP install replaces both OEM cats with a single High Flow 100 cell cat. The cars reads this as being less efficient hence the CEL's. It's not hurting the car, except that it's running a lot richer than normal.
Stuff the SRI or CAI.
Go the DP, big cost, but definite gains.
