messed up on mufflers

ordered pypes sma 10, 2-1/2 inch stainless pipe system did checking on mufflers, settled on dynomax super turo mufflers # 17733, thought I had the correct pipe set up offset in and center out, spend most of the other day trying to get the exhaust system to fit, finally see that I order the wrong mufflers need off set in and oppitsite offset out, place I bought them from will not take them back got them thu some type of clearance center only paid 67.98 for both of them along with free shipping great deal I thought, come find out not correct need dynomax # 17629 which run about 49.00 each and shipping, now trying to save the mufflers, seems like I will need to spread the rear pipes of the exhaust system so I have clearance around the gas tank, and fine tune the front of the x pipe to line up with the itt headers need to take a break and get my witts back to try again !!!! :oops:
