And it makes power

Joewee3.5

But wouldn't it make more with catless downpipes or catted for that matter. I'm sure the 3" makes as much power as the 4" but the OP wants sound. I just don't think the 3" is better for sound than 3.5 or 4".

I would recommening running stock y-pipe/cats + FR 3" catback alll day long over no catalytic converter and stock exhaust... i dont think anyone in their right mind could recommend a 3.5" or 4" exhaust to a guy looking to do long tow-hauls with a 3.5L gas engine...but thats just me. The ford cats are designed to have a little backpressure to function optimally. Not to mention most of the dealers we spoke to are 100% cool with a catback, bring up the idea of a catless dp and watch the attitude change quickly.

you have posted in almost every thread i see that you prefer the 3.5" or 4" - and thats fine, however you have zero experience with Full-Race products or our exhaust ... so agree to disagree

I'm trying to stay away from that 6cyl sound if at all possible, just looking to make the turbo louder out the exhaust. Don't think I could listen to raspy exhaust tone when driving all day.

to the OP,

Start off with a catless and/or catted downpipe. (shameless Plug coming up) For the catless look into our 3in bolt-on Mandrel bent Y-Pipe.(Link) Get the right tune for it with an SCT Programmer, the 3015(XF3) is tried and true and affordable. The Livewire is the one for you if you are a gadgetty person. The SCT gives you a world of options for tuners. Starting off in this manner lets you build the exhaust to suit you in which ever way you want. If you do the catback first and then end up getting a mid-pipe, you may be surprised to find out that you don't like your catback any more.

After the mid-pipe, maybe look into a catback exhaust. The chambered muffler Stainless Works Catback is one of the best sounding when used with a y-pipe. My best advice is to listen to clips online. Take the sounds with a grain of salt. but you can at least get a feel for what sounds like what.

If that is the result you are looking for the our off-road pipe with your factory catback is your best bet.

Agree to disagree is best. Thanks for all of your work.

I've listened to damn near every clip on utube and came up with either FR 3' cat back or SW cat back. I'm going to make my mind up and order one one em this week. Will it be ok to run my cai and catback w/o a tune??

Yes you will have no problems running it with out a tune

Does a aftermarket catted downpipe with stock exhaust make less power than a 3" catback alone?
