Here's my idea, but the pic i used isnt mine:

So far heres what i think i need interms of piping..i'll need a 180 u-bend for the last two bends before the muffler, but what i dont know is what the angle in the middle should be inorder for there to be a straight shot to the 2nd last bend..Also, the stock DP is 2", should i go 2.25" or 2.5"? And obviously i'm switching to a single outlet system because i dont care about looks

2.5" DP, spools up way faster.

knocking off a muffler. You will need all the breathing you can get. Here is a pic of a 2.5 into 3 downpipe. Then scale the pipe back down to 2.5 or 2.25 as you get closer to the muffler. This will help with spool up, and give you some lower end torque.

what size each at the split? 2.5"

I recommended larger sizes for you since you are getting rid of one of the sections.

Good deal. Hey, are you still looking for 17" sport wheels?
