Hello again. Darkstar, I think the look is a bit similar to a magnaflow as I'm sure you can see in picture from the link I provided. I also forgot to mention that just like K&N, Borla has a Million Mile guarantee! That was another HUGE factor in my choice. It just makes sense. As far as warranty goes breepsh, this was yet another point I thought about while shopping around. A local performance shop told me when I asked this and about passing my state inspection as they tried to sell me the HKS, "You really care about the warranty and passing inspection? You are the 1st person to ask us that." That can't be true. I'm sure most people have the same concerns we do. In any case, I asked the Subaru dealer where they installed it since they were also installing a GFB Blow-off valve at the same time about these issues. I was assured that since they installed it, if there are any problems at all, they would take care of it. Had I purchased it from them but had it installed elsewhere, they would not be responsible if something damaged my car. So, I can tell you that if you can find a Subaru dealer that stocks or orders aftermarket parts for the WRX and installs them, go with them. Certainly ask the same questions to them but I'm sure if you buy it from them and they install it, there is no way they can not claim warranty responsibility.
