New CAI, need advice on new exhaust

taz0624 · 02-01-2010, 06:57 PM

Just installed the new S&B CAI. I now want to put a better muffler on and open it up some but don't want it to be much louder or do any deletes. I just want a little more when pulling trailer as far as mpg and power, nothing big. Advice please!

Are you planning on keeping all of your emissions equipment? (DPF, EGR, Ect.)

If so then any exhaust mods (DPF back) are a waste of money.

i do plan on keeping all emissions junk

Then the good news is, you are almost done with mods

You can run a couple of different tuners for a little more power, like a superchips, or I think the smarty has setting for stock trucks. But keep in mind that running tuners with the emissions equipment installed can cause problems, as your filters may clog up more often.

I ran a superchips flashpaq, for a couple of months, and it worked pretty well, and I did not have any issues with clogging. It is also very reasonably priced.

But as for exhaust, the stock set up is fine. A DPF back system is a waste of money.

i dont want to do anything that may void warranty also< i just don't want alot of noise..

Removing the muffler with stock exhaust will make no difference at all. Dpf back systems are just expensive exhaust tips.

Understood, nothing wrong with that, but you are limited on what you can do for power and MPG.

What year is your truck?

2009 2500 mc

Power and MPG with the DPF is nearly impossible. Unplugging the EGR helps somewhat, since it lessens the frequency of regenerations. No DPF-back exhaust on the market improves sound or performance. It's a tough spot.

Hmm, what is your build date? You may have a locked ECM. Which would take a lot of the decisions out of your hands anyway.

I would just leave the truck as it is if you don't plan on doing any deletes.
