Sounds like you got it set up right. Do you have any pics of it? Any links to the pipe and clamps used?

Thanks, that all answers my question pretty well. Was just kinda curious, but I think im gonna end up putting a Thrush welded on, can get one for $24, might finish it off with a new tailpipe as well for an extra $25. But ill tuck mine better like you did, I think it'd stand a better chance against damage.

Mines cut after the cat. I don't have any issues with her running. Other than idling low when it's cold, but I just need a tune up.
It's really really loud though

sets car alarms off if ya get too close 😁
