I was contemplating the easiest hack on my stock 00' S muffler & reading this found me with drill in hand in no time. Your'e idea is brilliant. I drilled 2 holes 7/16 in each side & with a reemer punched them out to about 11/16. Used a 2x2 chunk of fir with a 'v'groove sawn in it to guide bit. It is a perfect note w/ minimal cabin drone which goes away @ 2800. I rarely run less than that anyway. It just screams when whooped! I also recently swapped stock header/cats for chinese headers ($69.00 +32.00 ship). They are awesome for the $ & collectors/welding is just great. Extended all 02 sensors placing pre-02's near header outlet (fitting provided in hdrs) & post 02's in top of pipe right behind 2nd cats, behind rear wheel well. I am now remodelling intake. All this fancy stuff available for $3-400 is great for a neurosurgeon, but I can't see it. I got some 3.5" silicon tubing (50%+- larger than stock dia) & 2 3" abs Street 45 deg. plumbing fittings, cut them down, rasped & sanded the insides to elim drag. The stock air box provided the short section w/ MAF hub when sawn up & removed, & I'm now patterning 3/32' uhmv plastic (or whatever it's called) for a new AB to house a 4.5x5.25, 6" long Conical filter from local ap store. I opted for an oilless K&N look alike for $20.00. It will be more of a plenum than an air tube, not much sucking hopefully, the fixed dia @ MAF must be maintained to get the cfm reading though. It will throw cel's I know, but with what I've saved I'll find someone to remap ecu. Working on this car is the most fun I've ever had with mech tools. What a great car. $15K for 31K miles, are u kidding? Rich mans garbage i guess. I won/t have 18 in it for a really fun fast ride thats so addictive to drive!
