I end up saying this to a lot of customers so I figured I would share with you in hopes that you guys can help educate other people when they are looking at parts like this.
So the price difference now comes out to roughly $25 price difference.
Because GrimmSpeed places their 300 cell catalytic converter to the rear end of the j-pipe, you are able to use all your factory exhaust shields around the turbo/j-pipe.
Now, let's add in the MOST important parts in my mind. GrimmSpeed is MADE IN THE USA and comes with a limited lifetime warranty. Do' you think a $25 price difference is worth it for those two things?
It's very important to remember it's not always about what looks like the best price...it's about what is the best VALUE.
But what about other catted brands not mentioned? These other brands are more expensive than GrimmSpeed, roughly $30 and 80. They are not made in the US, doesn't come with turbo gasket or turbo hardware and only includes a 1 year warranty. To me, that is a product that has NO value at all other than the name that is stamped on the outside of the box.
Remember to shop SMART not CHEAP.
