yes, the guys at NECO can share alot of opinions with you all. the install of the kit is the same on both cars.
as for the question about no mufflers. yes we can make kits without mufflers. also, we do make kits without tips. (some people want to use thier own muffler or tips). as for adding the magnaflow muffler, unfortunatly, we can only make the kits, using our mufflers. this is just how we have it all set up. i believe the guy "frank" did get a kit from us and added his own 18 inch muffler to it. it's not hard to add them, just something you need to do while installing the kit, so you know where to place the muffler.
the cost of these kits, is the same as our cougar kits. $310.00 for aluminized and $460.00 for our basic stainless kits. lifetime warranty on SS and one year on aluminzied.
take it easy guys
