I have a 05 Dodge 2500 CTD 325hsp. I am wanting to add a Quadzillaraider. What do I need to change on the exhaust? Does the k &n Help. Thanks lmk

 

IIRC, your truck already has a 4" exhaust. Straight-pipe it and call it good.

 

If you are going with the Quad race box you need to get a good set gauges first.Your exhaust should be fine (4 inch)coobie

 

rrsmtd,

A lot of members have been getting our MBRP performance replacement muffler as it's built from 409 stainless just like the stock system, has welded hangers that reuse the stock rubber mounts and fits easily to all the stock factory pipes, price is very attractive too. We even have cat test pipes so that if you want you can take the stock Dodge 4.0 inch pipes and make it a 4 inch turbo back system, makes the EGT's better and sounds real good too when you have your foot in it. Call us if you have any questions etc.
