poor mans duals.. Well decided to redo my 2.5 y pipe and go with a 3 inch y to dual 2.5 over the axel to some 6 inch long race bullets i have and dumps before the rear bumper to hid everthing. I picked up 2 8 foot peaces of 2.5 and 3 inch pipe for just over $40 and 2 hangers that were 3.99 a peasce.. so my set up on my 6 speed 02 camaro is full bolt on, 228/234 112 cam, 1 7/8 headers, and a moser 12 bolt with a 411.. dyno with the stock 10 bolt was 396/374 and never dyno with the 12 bolt so probably like 370's-380's. But is was through a 2.5 y pipe to a slp 2 to single 2.5 over the axel that slit to 2.5 duals.. sounded good but cant be that good for hp! so fair to yesterday this is what i got with just pie cutting and welding the 3 inch and the 2.5.. after the merge of the 3 inch its going dual 2.5 over that axel.. I know a bunch of ppl will say it will flow like **** and what not but hay i hade the bullets so its coasted meabout $50 for the hole thing so f*** it lol

Well your over the axle looks good , but I would revise the Y , I know you have a lot of time in it with all that sectioning but that driver side is not going to flow well and will probably rasp . Just split the old Y and go from there , or redo the drives side come off 20* straight 45* then reverse 45* to merge.
point is he didn't spend extra coin ... worked with what he had and spent under 50 bucks. & unless you're pushin upwards of 500 to the wheels it will flow absolutely fine i'm sure. like how people talk about crush bends cracks me up ... lets use a single setup as an example - nothing wrong with crush bends what so ever if you are looking to have say a free flowing 3" exhaust - use 3.5" piping & your only "restrictions", (which they wont be) will be points where your crush bends are which will be approx. 3".

IMO this is something I would not waste my time on pie cutting all those bends. I have other stuff to tackle and spend time on so the "extra coin" on pre made mandrel bends is worth it to me.
You can make a cleaner system in half the time for $150. But if you have nothing BUT time...pie cutting everything is one option.
