yes, i did contact them (Mitch Mixon?). they said they just do the coating, but not doing pipe modify anymore. Problem now is the outlet of the dpipe is 2.5" and will attach to 3" TBE. So i'm looking for muffler shop could do the mod for me before mailing T1 all elh/uppipe/downpipe. i guess it's better to cut/welding before ceramic coat a whole piece rite?
yes, this is the dpipe (see pic)
i'm not focusing power at this moment (supporting mod?), did lots of reading and found ppl said to avoid ringland failure on no.4 cylinder? will also pick up a getadom tube soon i install all parts/axle boot repair.
gtg, thanks again byron,
heading out with my dpipe now, will keep checking this post via my phone,see any shop could do (coz all of them said they either said don't have 3"flange or don't know what it is, yet need to see the actual pipe first). the most concern to me is they don't angle the flange correctly. x.x"
