What a mess this is hey bud! lol.. I found another site last night with pics of a fellow who did this. He used the exhaust out of a Challenger so had to modify the headers to fit, I do not
but, he used part of the stock exhaust piping like I was thinking. His install job is sweet, but he's complaining about loss of some low end torque. He did a dual in/out muffler and did away with the y-pipe and ran the exhaust on the drivers side right to the back of the tranny it looks like then crossed over there. I was thinking I would go with the 2.75" exhaust right to the cats, then after stepping it down to a 2.5".. Can't find a step thou, MBRP makes a lot but not that one. At least I have the O2 extender harnesses.
I don't have air care where I am so I could hollow the cats out or just delete them, what about the O2 sensors and with a DSP how do I make it so they don't throw codes?? Crap what the hell have I done.
Oh and SS4Luck, just wanted to say I love your truck man, the LED's are badass bud! I ordered a pair of amber PUTCO Nova LED's for my front turn signals, think they'll throw a code? Should I get resistors? The bulbs were a tad expensive, 65 bux for 2. Also got their 6000K hi beam to go with my very soon 6000K lo beam
And I bought a mini 12" Fire & Ice bar for the rear. But we'll need to talk about your lights soon enough as they look AWESOME!
Ok enough writing. Peace out guys!
