Bad news is my cats are bad and inspection is due in Jan and we have emission test. Good new is i gonna get those bbk H-pipe and converter set-up. My question is it bolts right up but the pipes are 2.5 in and i thought the stock pipes on a LX are 2.25 so what can i do to make this work. Thanks

i have a stock h pipe if your interested, it is in great shape. you'll need to get 2.5" headers to fit. no point in having 2.25" restrictive headers, to 2.5" midpipe, to 2.25" cat back.

um i passed with NO CATS, they only take the reading out of one tailpipe( 4 cyls), if your in good tune, turn the timing to stock and you should pass.

a muffler shop can weld in a piece to make it work
