4 or 5in exhaust

Hey guys

Which size should I go with? Any sound difference?

Another question if I buy a full exhaust could I just run from the dpf back until I find a tuner? I wanting to get rid of the factory exhaust look?

Thanks brad

I've got a 5 and really like it. It's just a little deeper sound. Also if you buy a full exhaust it won't bolt on to the dpf so it's not that easy.

Well I guess it just depends on the exhaust. My flopro exhaust uses big band type exhausts clamps to connect the pieces together but the back of the dpf has studs where the tail pipe attaches.

I suppose you could get a dpf back exhaust now then just get a delete pipe when you tune it. That should work, but that means the only size you can get is whatever the stock size piping is.

Ya I have had a couple opinions cross my mind. Thought about getting a 5 in dpf back exhaust and getting a delete pipe when I find a tuner. Or I thought about getting a full exhaust 5in with a band clamp or something after the dpf to make it fir for the time being

Save money buy whole exhaust and do it all at once. go 5" you'll always wonder if you should have gone with 5" if you buy 4".

aFe has a really nice full 5" SS w/ muffler. All the other brands I looked at were 4" up to the tail pipe and then jump up to 5". aFe was the only one w/ a full 5" (when I did this a year+ ago.)
