i know some company sells midpipe for the sc300, but my question is does any company sells a midpipe at least 3" that will be long enough to also delete the stock cat, or should i just take it to a local shop to do it if they're willing to?

 

I would go to your local shop and get a pipe fabricated / cut to your desired length and girth.

I would probably be cheaper than a company selling an "Sc300 midpipe"

It's just a pipe. Unless you want titanium or flex pipe, etc. The local shop could probably do it.

I have a local shop here that is great! They can do it all. The place is a mess when you walk in, but these old-timers know their parts and will cut pipes for any application for cheap, bend them how you want, etc.

I would even print out a pic of the "SC300 specific" pipe and take it in for them to see, then they'll fab/cut exactly what you need. Just make sure they can bend it if you need any degree of bend.
