I would like to put some performance exhaust on my 850T before an ECU upgrade. IPD offers it but at a $700. I realize it is stainless but if I could get a local muffler shop to bend some pipe, 2.5" I guess, and I put a performance muffler on would I get the same performance gain as the IPD system? Also I would have to find a muffler that was not too loud. I am 37 and don't want me or my family to have a headache everytime we ride in the car. I would be willing to sacrifice the stainless material for galvanized steel and save the extra $ for some other upgrades like the ECU.
Any thoughts?
Thanks
Ed
