If you are getting headaches, the first thing I would check is your eyes. Seriously. If you wear glasses, your prescription may have changed. If you don't wear glasses, your eyes could be fighting hard to maintain focus. If one eye has less acuity than the other, it will cause severe headaches.
I did the hogzaust today and the noise is nowhere near as loud as my 92 Eagle Talon and it has no exhaust leaks. My Talon is MUCH quieter now that I added more exhaust system to the downpipes, but even with a good muffler, it is still louder than the hogzaust. At cruising speeds, I can barely even hear it.
My 15 year old daughter (who loves my Talon) just kind of said, "meh", about the new tone. My friend (who built my Talon for me) agreed that it sounded meaner but I could tell he was trying really hard to be open minded about a mod that is not strictly for *performance.
However, I have some interesting news about performance. I did not think it was worth it to do a before and after dyno run for it. That would increase the costs a thousandfold! But...
My butt dyno said that there was at most, 8 lbs more torque. Most of that, I attributed to the new sound. I am like a kid with a bike who puts a clothespin and a card so the spokes click, so I figured it was probably ALL my imagination... but that may not be so. Read on:
There is a stretch of private road just over a quarter mile long near my house. I have done several 3rd gear runs on it starting at 2000RPMS. I always top out at about 92MPH before I have to stop rapidly. An hour ago, I topped 100MPH. WTF?
My car is mostly stock. There was some sort of aftermarket intake air filter in it when I bought it. The only change has been the hogzaust. There is no way bypassing the mufflers would create 10 extra MPH. I have no idea WTF is up. I am going to hook my Tactrix cable up again and compare a new third gear run with several older logs I have of the same run. I will post here again if I find anything interesting out. Very weird. (I bought the Tactrix cable for logging, I already have a badass car I can reprogram)
