right now i have pacesetter lt's, ory, and spintech catback. it sounds good im just wondering if they flow bad or not? ive read mixed reviews. ive heard they flow almost as good as straight through mufflers and then ive heard they are a big cork. could someone post some truth in the spintech mufflers?

thanks

 

Anything else done to your car? If your just a bolt-on car, you won't notice much if any difference even if you bought the "Best flowing" true duals, so if your happy with the sound, I wouldn't mess with it. There are much better areas you could spend your money. Tune, Suspension, Drag Radials, etc.

 

i am just bolt ons right now. i would like to build it one day to a 383 with ai h/c. i have a manual cutout in the I pipe before it goes over the axle. i notice that when i have the cutout open and rev it, it revs up much quicker than when its closed. does that mean that its a big restriction?
