Catted DP w/ Catless CBE vs. Catless DP w/ Catted CBE

6EPLN · 11-23-2005, 12:23 AM

I want to get the APS 3.5 TBE, but my dad wont let me because its catless. So i need to have a cat somewhere in my setup. Is it better to have a cat in the DP or in the CBE? Im wondering if it will make a difference? What will be better performance wise, and also sound wise. I want a LOUD exhaust setup. So what do y'all recommend? Thanks for all the input.

In the DP. I believe the cat flows better when its hotter. Just get a DP with a highflow cat.

get the Turboxs downpipe and RFL catback... this allows you to keep the bottom cat i believe, then you can just buy the midpipe (testpipe) later on and have a fully catless system
