    Sounds like an unnecessary PITA.

    I assume you mean the upside down foxhole where the downpipe and cat live... I bet you could totally put one pipe on top of the other rather than next to eachother like you're probably imagining.

    If you're going through all the trouble of true duals, why have cats?
    Irridium spark plugs last 100k mi and work just as well as copper. Copper is a waste on N/A and only lasts 15k mi. Don't use Platinum.
    Use 195* tstat unless you can thoroughly explain why not; 99.9% don't need a lower temp.
    Almost any oil filter, ever, is of higher quality than ACDelco. Spend $6+.

    You are silly. Illegal, who is going to find out unless they get underneath your car. I run with no cat but have stock mufflers to keep it quiet cause these cars sound like **** with loud exhaust. Then again to my ears anything thats not a v8 sounds like ****.

    Pretty sure a cop wouldnt get under and check cause i dont fit unless its on blocks or somethin. Its more like my dad doesnt want me to do it cause its technically illegal. However theres at least 4 kids at my high school (of like 350 or 400 kids. huge school im tellin ya.) that have no cat and dual pipes with hardly any restrictions and the cop sits right outside the lot (yes theres only 1 cop on duty at all time in the town of like 785 people). The one kid cuts off his exhaust and strait pipes it and all he gets are those "fix it" tickets so he puts the cat on and takes it in for it to be checked and then goes back home and rips it off.

    Not mine, the car isn't running. It has pacesetters with tubing coming out of each collector straight back.
