I HAD MY 40 SERIES WELD ON AT A LOCAL MECHANICS SHOP, BUT INSTALATION WAS STRAIGHT FOWARD. I LIKE THE SOUND, BUT I THOUGHT IT WOULD BE LOUDER THAN IT WAS. NEXT FLOWMASTER WILL HAVE TO BE A RACE 40 SERIES. I DIDNT NOTICE ANY PERFORMANCE DIFFERENCE EITHER, DONT KNOW IF I WAS SUPPOSE TO THOUGH. OVER ALL WORTH THE 80 BUCKS I SPENT.
