This is what I did. Go to your auto parts store and purchase FLO-PRO Flex coupling part # FT17504N and 2 x 1.75 HD muffler clamps. Take the muffler off the car and cut off the both ends of the OE flex coupling. The new flex coupling should replace the OE. You might have to cut 2" on each side of the new coupling so as to get a proper fit (length). Do a couple of mock fittings to get the proper length. Use your muffler clamps on each end and your done. I did this 2 years ago and after a lot of driving the replaced coupling failed.(I thought mine was supposed to be stainless steel but apparently not and it was an off shore manufacturer) But it was an easy cheap fix. Cost me $15.00 Canadian for the new coupling and clamps and should keep me going for 2 more years. Good luck.

Sorry, I don't. After I posted, I said to myself that I should have taken some pictures.Any photos?
I got it from a Company called National Exhaust. Their phone number is 905 453 4111. They are located in Brampton. Let me know if you need my help.
I've seen flex pipes at canadian tire. They were rather pricey though. Something like $40 or $50 and they weren't even stainless steel. I'm planning on ordering the clamps and flex pipe from rockauto. There's a 1.75"x8" w/ ends stainless steel flexpipe for $8.
What did you use to cut the flex pipes/exhaust? Something like this? https://www.canadiantire.ca/en/pdp/oem-tailpipe-cutter-box-1250057p.html?rrec=true#spc
Mine were 1.75" Inlet and outlet. The flex pipe had ends on them and the overall length was 8". That was too long so I used a hack saw to cut 2" off each end to get the correct overall length. This is going to be a trial and error method. The original flex pipe blew apart and fortunately did a clean cut off the flange end of the muffler. Luckily I did not have to remove the flange. This allowed me to slip the end of the new flex pipe over it. The other end (muffler)had a bit off the old flex pipe left and I cut it off with a hacksaw on a work bench. This is my recollection what happened 2 years ago. This time, the removal and installation was a piece of cake as I just had to undo the 2 muffler clamps and insert the new shortened flexible pipe. I still am baffled that this piece only lasted 2 years considering it is supposed to be "stainless steel".
