Muffler bypass questions

Need help to do the muffler bypass I have seen done by several people on the site. I have purchased an S muffler (love those twin tips) but have run into a wall trying to get the stainless steel bypass pipes, much less finding someone who can bend a pipe smaller than 1 1/2". I have found one vendor on ebay with sections of 1" pipe with a .065 wall. Does anyone know if this will work? I am even considering buying a small hydraulic pipe bender (about $100 on ebay) and bending it myself. Again, any knowledge out there about what is needed to bend this type of pipe. Lastly, I have found a local place that can supply me with 1 1/2 inch non-stainless pipe which they can bend and install. Since this is my easiest option, has anyone used pipe this large? I am not sure this would leave enough room to install the muffler in the car. Any input would be appreciated. I am pretty determined to make this work.

Do you mean you need secondary CAT bypass pipes? You can buy them from Fabspeed for $495 and maybe cheaper else where (lose 25 lbs off back of car too vs. with secondary CATs). But I would not go cheap. You end up paying for it later. Also, forget about going with 1" pipes just because you can bend them. Why restrict exhaust flow and choke off HP?

Bypass clarification

Sorry for not being more specific. I want to add a pipe to each side of the muffler from the input pipe to the output tips, bypassing the muffler with part of the exhaust. I don't know the exact name for this mod, but I have seen several postings with pictures, as well as an english company selling mufflers like this on the UK ebay.

I think you meant like in the above links.

Now that I think about it, why is there a need to use stainless steel? The exhaust from the manifolds back to the muffler is not stainless. I can think of no reason to use stainless other then it is nice.
