I've been experiencing many problems with my aftermarket midpipe. I bought a cheap 3 piece cat back system and it is all my fault, however I would like to try to put an angled style axleback muffler on my stock midpipe, but im not sure if it will fit. Has anyone on here done it before. Please let me know!

 

People have done it before. Looks up the numerous exhaust installs on this site. Depending which year tC you have you may or may not have to buy additional hardware. On my 07 the nuts were welded to the midpipe flange so I had to go to a store and buy some bolts that would fit my Tsudo axleback exhaust I had at the time.
