Ive got a SI/SO flowmaster 40 series, dont have the money to switch to a SI/DO right now but i was wondering if its possible to have a shop Y pipe the end of my SISO to run dual pipes out the rear. If this is done will it effect my sound because i love the sound i have now but i want it to sound even and not just louder out the right side. Any help is always appreciated. Thanks

 

Iv never done it but yes,,you can do that.
It will sound good and not much different then it dose now.

I'd just wait til you can get the correct muffler. If you get it done your way, you'll end up regretting it until you do it the other way. It wont sound as good or as evenly as a SIDO either.

 

Yeah it will give you the dual look, but its not worth it sound wise.
