Its for an A-body w/ 505 ci little over 700hp and anticipate running high 9's to low 10's or even slowing it down and running super street or PSCA 10.60. Trying to stay in a budget, but do not like to comprimise w/ quality or dependability for small $ increase. Thx Steve

Other wise I run a pipe ( same size as collector ) to a race muffler ( three chamber ) and dump just in front of the axle. Fastest 300

I run that back and it dumps out the side right in front of the rear tire. It is still loud but knocks that edge off for sure. Here is an in car clip. http://www.youtube.com/watch?v=4hqD4OzpCpU

Have not compared them on track as opposed to open exhaust but they sound nice. I personally don't like the tin can sound of the Flowmasters. Fairly quiet till you it I used a 18" collector extension then the muffler then a section of pipe with a turn down just before the rear tire.

The mufflers are 3 1/2 in and out. The inlet and outlet are centered on the muffler and you can look right through them. Very sweet, low rumble and not raspy at WOT like some.

Car went 9.02 at 149 with this set up, all motor. The Barracuda has a set of Dynatech collector mufflers on it. Been bottom 8's at 168 with them. Here is some sound from the Valiant from a walkaround video. http://videos.streetfire.net/video/Walkaround-of-B1-Mopar_90841.htm Here is some of the Barracuda with a little idling http://www.youtube.com/watch?v=PuhfPsfYBKg "I am not ashamed to confess I am ignorant of what I do not know."

I used a set of Hoocker 2 inch A body fenderwell headers and a three inch pipe from the collector to behind the rear axle and then into a Magnaflow three inch by 14 inch long oval muff exiting at the rear bumper. This is a street car and the noise is not bad until you floor it The car has gone 10:34 cork up at 128.6 MPH in the 1/4. I have not treid removing the exhaust at a 1/4 mile track yet, I have done that at a 1/8 mie track and the difference in ET was .04(four hundreds)and about a 1/4 mph, not worth the effort, especially when bracket racing. Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
