Im having exhuast issues right now. Truthfully i am just getting started at this and am just starting to learn everything. I have been told by various people that it is possible to use GT x pipes and catbacks on a V6. If this is true i would like to put a magnaflow x pipe with cats for a 99-04 GT on my 99-04 V6. to match up with the x pipes in the back i was planning on a Magnaflow Magnapack system for the 99GT. I know the catback and the xpipe will match up but im worried about the MAC shorties coming together with the xpipe. Please can anyone help me out im in desperate need of help. All i need is a simple yes or no if these things will come together fine. (MAC shorties,xpipe with cats for shorttubes,and the Magnapack catback) I greatly appreciate any advice you can give me. Thanks
