maybe some help here...
...as far as any visual checks from emissions, no ideas for them looking at the shorties but I've had my converters on my Chevy truck gutted and had a straight thru pipe put in so it looks like they're there and the straight pipe keeps flow without it bouncing around in the canister. of course emissions tests will prove otherwise. And on my X, I also put the 24" Magnaflow Muff with dual inlets and single out to eliminate the 'Y' or 'H' pipe contraversy that also saved space....
...maybe some help.
