I know all this has been covered before, but it is scattered all over the place I'll try to consolidate it into one thread. One, the exhaust may or may not need to be extended. It will either be about 2" short or 1/4" short, the latter does not need an extension added and some even think the first doesn't either. Two, the FXT hangers are about 1.5" center to center. So you either need to use the Kartboy XL hangers (realize they will transfer more sound to the cabin compared to rubber) or any generic hanger that is roughly 2.75"-3" in length (this will give about a .75" gap between the tip and bumper so no concerns about the bumper melting). I found some at Autozone for $4, but after removing the midpipe the hanger is about the right length and probably could be used on the rear. If you go with a generic hanger then realize you will have to ream out the holes since they will be too small to fit the Subaru ones. The other option here is to heat and bend the hanger arms on the muffler up about 1.5" and use the stock/shorter hangers. Three, I replaced the midpipe as well as the axleback and it has a nice deep bass burble from idle to 1500 RPM's, after that is basically just as loud as the FXT cat-back (no highway drone). Finally this is EXTREMELY easy to do and if you are hesitant go ahead and do it, you'll love the sound (just right, loud in all the right places). The rear hangers are your biggest concern, the exhaust doesn't sit any lower than stock it tucks up rather nice. If you bend the hanger arms you will have less lateral movement compared to the longer hangers. Hope all this helps narrow things down. Please post any questions about the install and I or someone will be more than happy to help. Now get out there and put this on already!
So I put on a Turboxs AB today and measured the STI midpipe, and just as I remembered it was exactly the same length as the FXT.
Tip:....................6 5/8"..........7 1/4"
Muffler:..............17 1/8"........16 1/2"
Overall length:.....46 1/2"........46 1/4"
midpipe...............49 3/4"........49 3/4"
Again these measurements are from a 2004 FXT and 2006 STI.
2004 FXT A/T (vf43 08 STI TMIC)
