Default Magnaflow question

Hey guys I just went to autozone and saw a magnaflow muffler there and decided it was time to get one. Without knowing much I bought it for near $100. It's a offset in center out muffler. Now when I got home I measured my stock muffler and it's 30 inches long...The magnaflow is only 20 inches...Will this work if I buy more piping? Or is there a different magnaflow that I shouldv'e bought?
Thanks

Yeah aftermarket mufflers are usually always shorter. If you know how to weld then it wont be a problem adding more piping, unless your original piping is rusted then you might as well take it to a shop and have them bend you new piping from the muffler back, and if you're going that rout then you might as well go with 3" pipe like me And if you take it to a shop dont pay a whole lot more than 150$ for the service.

No, larger pipe = better sound IMO. Its a little deeper with bigger pipe. Oh and yes 2.25 is stock i believe.

Oh and if youre thinking the muffler will give you more power it wont.. Maybe a little better throttle response, but most of the resistance in the exhaust is made by the stock catalytic converter and not the muffler. But even replacing the cat for a high flow cat wont do a whole lot. Theres a lot you would have to do to the exhaust manifolds to see the aftermarket muffler and high flow cat do you any big amount of difference. Also a larger diameter intake (like perhaps a cold air intake) would also be needed. Stock intake is only about 1.5 inches at its most restricted point.

I got a spectre CAI and put the magnaflow on last night, I removed the rest of the tailpiping from the stock muffler back, installed the magnaflow and dumped it off just before the rear axle. Sounds louder than I thought it would but sounds nice. Gotta fix some welds though, a little fumey in the cab.
