Just finished installing my gauges, got 4 in, EGT, Boost, Fuel Pressure and tranny temp. I just got my Edge juice with attitude in, I chose this because i like the ability to change settings at fingertip touch. My next mod is gonna be the ***** whistler intake, then exhaust. My question is now what do I do with the exhaust? Do I remove both the cat and muffler? or keep one or the other?

There are no regulations here for vehicles, so it dosn't matter. My plans are too use this as a daily driver and occasional hauler, But I wanna be able to put the hammer down and leave a durmax or powerstroke behind. I want it to remain dependable and last for a long time, I have plans to upgrade the tranny with either suncoast or something along the same quailty eventually, Im hoping to get a fas fuel system once it warms up so i can run the chip without choking the engine, Any comments or suggestions are welcome!

 

If you are trying to better your truck without making a lot of racket, I would leave the Cat in and put a Donaldson 51" muffler. Has sound almost as quiet as stock, but much less restriction. about $80.00 here in the USA.
Personally this is what I did, I like my tunes too much to a loud exhaust

 

id do a muffler delete from genos... sounds real good

 

^ What he said.... can't go wrong for 80 bucks shipped....
