So i have the Dinan exhaust and i want it to be alot louder, i originally planned going to a twin inline borlas the xr-1s straight back to the dinan tips but is there a easier way to get relativly louder exhaust by modifing it maybe cat removal? highflowcat? without harming the car or something? not to familiar with car exhaust coming from driving trucks

 

switch the mufflers to magnaflow 11366 mufflers.
if you did both sides it would be slightly quieter than this (this is single sided) http://www.youtube.com/watch?v=hXr6k...eature=related

in a week or two ill post my setup with 3 vibrant resonators and that muffler.

 

the dinan is single sided, and thats just how mine sounds im looking a little louder

 

Have you thought about removing the center resonator.......replace the whole section from the flange back to the Dinan with just pipe.

It's how I run with the JCW exhaust.

 

removing the resonator will definetly help with the loud factor. Do you have the catback exhaust or the axleback exhaust ?
