Best after market exhaust?

[Ghost Hunter]

Time to replace the exhaust on my 2005 Ram diesel.  Any recommendations?   Cat back?  Turbo back? 4" vs 5".  Any help appreciated.  Got to get it done before spring bear season.

The factory exhaust is good for about 500hp.  Unless you have plans on more than that I'd just do something similar to stock.

MBRP ...in my opinion

MBRP  also, went 4" turbo back stainless on 2000 Ram, easy install

I have the banks monster 5" on my 04 GMC 2500 diesel. Not that loud at idle but it sounds really good when you get on it.

Ordered the MBRP SS 5" Cat back.  Hope it's as easy as it sounds.  Looks like I have a project for next weekend.

A lot of dodge guys like the Diamond Eye. Depending on what mods you have 4" is usually the best for our common rail trucks.

I bought thier Kit for my 03 and installed it. Its sweet! I can tell you tho it is loud when above 2krmp or lugging it at 1300. Cheapest 5" kit i could find and its been working great for over a year now... Highly recommend

I have a Diamond Eye 5" on my '07 5.9 and love it!!! Low and deep and no annoying drone in the cab.  Not to mention it's one of the cheapest available.

yup!!
 actually a 4" exhaust is good for over 600 HP. at that level, the difference between a 4" and a 5" exhaust is actually only about 5 HP. hand calc's and also tested by the Ripster himself.

unless you start upgrading fueling AND the turbo, it's not worth doin muich to the exhaust excep a kitty delete.

my 2001 CTD with twins has a 4" exhaust. Primary turbo is a garrett GT42-02 with a 1.15A/R T4 turbine housing. It has a 4" outlet. The engine is currently making 635 RWHP.

Unless you want to sound like a Freightliner.

I did this to my 06 Ram, still wasn't happy with the EGT's.  Went to AFE 5" SS Turbo back and haven't seen over 1200 degrees since.  Even towing a 10,000 lb trailer over the pass.
