Hey guys,
It's time to get rid if the stock exhaust on my car. I have read that the stock system is good to 400hp and I'm currently sitting at 300hp at the crank.
The dyno tuner I bring the car to recommends going to 3" exhaust and I've read forums where Overkill Performance highly suggests it as well...but if course the elephant in the room is finances.
I have access to 2 old Duramax (3.5"?) systems that will give me basically all the piping to redo the GP exhaust. The ID on the pipe is 3" - 3 1/4" (not a mandrel bent kit).
Anyone have any input on the downsides of repurposing the old duramax system to save a few bucks?
