Which is the best cat-back for fitment around a large wheel/tire combo?

[mbl585]

I was originally going to go with the Mac Cat-Back system for my 91 LX 5.0 but found out that there might be problems with fitment around wide tires (15x10 Welds (6.5" bs) w/275 nitto dr's). So now I am looking for a 2.5" cat back system that will fit what i'm running. Any suggestions?

Almost every system I have seen rubs a small amount with the large tire and wheel combo with out custom tips.

The MAC system has the ball and sockets for the tails which allows some side to side adjustment, not sure if it would clear or not.

My mac cat back didnt rub when i had the 10s. Neither did my dynomax ultraflo catback that i have now.

JS90Lx....what size tire and what is the backspacing of your rim?

my father has been a mechanic for like 30 years and hates to do exhaust work... the only kits he works with are flowmasters cause it only takes him 10 minutes to install and he never has to deal with any problems with them...
