ok so i decided to get 5zigen fireball axle back along with custom mandrel bent piping, so i went to one of the biggest muffler shop in town to see if they can make it. the answer is NO. instead, what they would do is to use 2-3 U pipes depending on how many bends are on my car and weld them. and they want $220, including, flange, hangers, gasket, 2.25 pipes and labour. They said, there's no one on this fawking island, Victoria, BC, that has mandrel bender. since im a noob about this, im not sure if 220 is a good deal or not. does any of you can help me out on this? will 2.25 custom piping really make a big different than stock pipes, sound wise?
