For any of you guys out there with a maxima that are planing to do an exhaust on your car i personaly think u should go with mandrel bent 3 inch, it increases the air flow by 35 % over a 3 inch pipe from some muffler shop. I have a friend that changed his 2.5 muffler shop exhaust to a mandrel bent 2.5 and it gave him about 40 % more horse poweron his civic, and its basicly the same price compared to some muffler shop maybe like 50 dollars more, and as a result to that im getting my custom y pipe done and my full exhaust with a straight pipe in 3 inch by mandrel and it will help out my turbo soon to come and hopefully i can get all the way down to high 11 low 12 in my 1/4 mile. I have a guy down here in utah that does it and the estimate he told me on my exhaust was 4 to 6 bills and i think its worth it, and he does custom exhausts for nascar, if you have any question drop me a line at
