MasAyinde Posted June 17, 2011 Share Posted June 17, 2011 Isn't the 2nd one on the DP the least restrictive of the three though? I plan on getting a Shorty DP for stage 2 and keeping that 2nd cat. Link to comment Share on other sites More sharing options...

MasAyinde Posted June 17, 2011 Share Posted June 17, 2011 Not overly concerned with passing the test; there's a shop here that only check for codes. Link to comment Share on other sites More sharing options...

Blk2.5GT Posted July 1, 2011 Share Posted July 1, 2011 You can find used uppipes and downpipes for decent prices. Sometimes it takes a while to find what you want for a price you want. I found a used Turbo XS flex catless uppipe on here for $85 with shipping. I would get a catless DP for all the reasons that were already metioned above.
