Thats exactly what I would do if i got quads. It looks cleaner than that piece of plastic on the mtech IMO.

No, they are fine. You must delete cats or get high flow cats if you retain the stock pipes in order to see any noticeable gain. These remus tips are only mufflers(sound and look only). If you get catless downpipes and delete secondary cats and get the remus tips you will be good until about 500-600whp or so. Backpressure become an issue then. More hp the wider the pipes need to be.

I wouldnt zip tie anything in the exhaust, as it would probably melt. I dont know much about the electronic valve because I got rid of it a long time ago. Exhaust was my first mod. I know its meant keeping exhaust decibles down during startup, are you talking about the golf tee mod?

It looks like the x-pipe is used to soften vibration noises from the stock exhaust. It performs LIKE a resonator but it is not one. Its just reinforcement for the pipes at the mid-point. The longer the pipe without reinforcement like that the more vibration you will get. I dont know much about the valve, I dont think it is needed. I have been without one for 20k+ miles with no issues. I think its mainly for noise restriction on startup and when you arent WOT. The stock one opens during WOT

You asked for it, so here it is. TURN IT UP!

does the straight pipe that you added go inside or outside of the muffler? And how about on the other side does it go inside or outside or does this not matter?
