SLP x-pipes

2000gt w/ MAC catback. im thinking of an x-pipe to buy soon. My question is will the SLP fit the MAC and stock headers? im leaning towards the SLP beacuse of the design, that way i wont have to buy a new X-pipe if i go LTs.

Also any other suggestions for x-pipes?
 
uhm. you'll have to get a new x-pipe later if you get long tubers anyway.. because the long tubes (are longer than shorties/stock manifold) so you'd have to get shorty x-pipe.

so either buy the 2 at the same time, or stay with shorties. the connections on the xpipe > catback systems are universal pretty much.. **** will fit :)
