I'm looking at the Jim Wolf Technology 2.5" stainless cat back system for my '91 TT. I like the look of the single 3.5"x4.5" oval tips. Is anyone running this system on their Z's? The forum seems to feel that single tips are preferred for TT's because of lower back pressure than NA's. The Jim Wolf system is $950, so they are a bit lower than HKS or Stillen. Any thoughts?

 

Back pressure has really nothing to do with the tip design. Just buy what tip design you like.

 

if you are concerned about back pressure, justmake sure the pipes are 2.5...the tips of the exhaust are not going to play a factor in that. also, look at courtesy's website w/ their exhaust, few people have it and say they like it.
