I have SI/DO system now, believe it is roush street system with 22" mufler. Looking for better sound/power. Does anyone know how long tube header with flow cats and then probably a set of magnalow mufflers would sound?? Dumbquestion but I'm hoping smeone has already tried it..Thanks

 

Anyone?

 

I Can't speak for the Roush system since I've never had one but I do have a Flowmaster 10 series, single chamber, single baffel, si/so dumped at 45* and love it. Everyone hears you at startup and everyone on the road knows that you're there without having to stomp on it. If I do stomp on it it sounds like a supercharged Mustang. Just my opinion though.

 

Longtubes & high flows = loud! haha and combined with maggie mufflers, very deep toned & loud. So you will be heard.
