I tested them when i got my mufflers done, they sound good on V8's but I didn't like them...too quite, I didn't like magnaflows or glasspacks. flowmaster 40 rumble like big block at idle and still raps great at like 2100-2400 rpm, you wont be disappointed, I tried them all...just my opinion

you can lead people to truth, but you can't make them see it!
