As you probably already know, Magnaflow does not make an IRS specific Magnapack catback for the 99-04 Cobras. If you swapped to a solid axle, you are OK though (because the catback for the GTs will work).
The easiest way to run Magnapack mufflers is to just weld in a pair of Magnapack mufflers into your factory catback.
OR, if you want to run a "Magnapack catback" with your IRS, you have to purchase the regular Magnaflow IRS catback for 99-04 Cobras and additionally purchase two Magnapack mufflers, then swap the regular Magnaflow mufflers out of the catback for the Magnapack mufflers (takes a little bit of pipe bending if I'm not mistaken, to ensure a proper fit).
You can then sell the leftover magnaflow mufflers to recoup some of the extra money you spent...
does anyone know for sure what size i should be geting, 2 1/2 or the 2.25 mufflers to use with my stock exhaust. i ordered the 2 1/2 yesterday so hopefully those will work.
thanks jordan
