Other exhaust questions...

[Desert Viper]

Been reading the thread concerning the H/X pipe. I'm getting ready to have a complete new exhaust installed. I' thinking of 2.5" from the manifolds back, with cats deleted, with a 4" single from the buffler back. Is this big enough? I heard I can increase HP by this type of set up.

The cat delete is where you get your HP. Not sure how the 4" single will affect things. Most people are going with either the Magnaflow, Mopar/Borla or B&B catback. There are some who have experimented with their own configurations such as Flowmaster or Corsa.
