My truck has 3 cats and only the 2 have sensors, if I had the third cat cut would I get a check engine light? I want to run 3" the rest of the way into a flowmaster 40 and out in front of my rear tire through dual tips. Is this going to gain some power?:confused:

It won't throw a light, your sensors only monitor the precats. Gains probably wouldn't be huge, the precats and stock manifolds are the big restrictions in the stock exhaust setup.

I took all 3 of my cats and ran a set of gibson shorty headers into 2.25 pipes true dualed with turn down flowmasters along with a pair of 02 simulators , I picked up .5 sec in the 1/4. The previous exhaust was gibson shorties along with a flowmaster in place of the stock muffler.

Got a full borla stainless system on mine.

Headers, Y to 3" to a 19" muffler and tail pipe

Sounds good!! How loud is it in the cab while normal driving?

if you keep the pre-cats it won't be as loud. Mines was pretty loud inside and outside the cab. I am now running jm's longtubes 2.5 x-piped duals with 2 dynomax 12in race bullets and it sounds absolutly sick. I will try to get a video up this weekend.

No drone or annoying noises. Keeping the tailpipe exit way out back helps I would imagine
