OP's keeping his exhaust, so you can continue discussion

 

rob145 - I'd be interested to know why you were even considering getting rid of the Top Speed Y-Back. Not what you expected? Too loud? Drone? In-laws don't want to ride in your car now :-)

Seems to me that TSP still represents one of the best values out there. In addition, they maintain a constant diameter from the Y-Back (just over 2.25, or 60mm), so it's an improvement over stock (50mm to the mufflers from the exit of the midpipe).

 

Basically for money buddy. But decided to keep it and will scrounge money from elsewhere!
