tubbytreats - great write up and pics. Might want to include the midpipe donut gasket in the items needed - mine was frozen/rusted onto the catpipe. So, I "had" to run my 3rd cat. I had an experienced wrench do the majority of the work, but I just read the write up to put words to what we were doing.Originally posted by tacomaboy138
awesome...I cannot wait for my warranty period to subside.
BAAAHHHH!!! Do it, do it now! I had my STi UP/monster pnp'd TD04/Scoobysport TBE done this past Saturday for my baby's 16th month birthday @ 23,000 miles. The difference is amazing. I can't wait to get my UTEC properly mapped and put in the 3rd cat delete - just for kicks. I'll probably run the 3rd cat most of the time (emissions testing). But, spool up was sooner, midrange was much stronger, and a little on the top. Lots of audible changes like spooling noises, little pops and crackles, and the rumble. I do have an odd fluttering noise during part throttle lift off. Not sure what that is, but it's too cold to be driving around with the windows down.
