So I just finished the install. Bit of a pain, figuring my 13mm socket broke :evil: and I also took the resonator completely out and fit a 2.5" straight aluminized pipe in it's place. Most of the issue was getting the cat out, as it was sort of a puzzle. Other than that, I wouldn't say it was too bad. Advice for others would be to have another person with you as it will save you much more time and be a lot less frustrating working as a team and being smart about it...I'm currently running JZW stage 1 with the CXRacing FMIC, Custom CAI, and the car runs and pulls great. With the resonator out it sounds a little more aggressive and slightly louder, but not stupid loud. Might save a new muffler for a later project, I'm pretty content with it right now. I might run it a little more on the highway when I get my tags tomorrow and I will be more able to notice the power increase...but for now I'd say roughly 300 for everything I bought to complete the project is not bad at all...and quite worth it. I'll prob get some pics up tomorrow when it's brighter outside.
