Sounds good, what magnaflows? Here is mine with a 3 1/2 X and 3 1/2 Bullets, I had to cut the X cause the headers that were in this car were Hooker super comps, and they were narrower than my Hustler's with those adapters, anyway after trying to figure out where to cut it and how much to weld back in etc so i could get it as close to the rear of the trans as possible, cause that's How it will be in spring. I ended up with a 1/4 gap at the top of the drivers collector ,cause the bullets were hitting the bottom of the floor by tunnel, this was just to hear how it sounded it with them, I will change it or just get a New X I haven't decided yet, But it sounds good! When I revved it the smoke is from dumping trans fluid down my carb from before to store it, and the mic kinda gets muffled when it is revved up too. This was just a test tho as its 50 here today !! Turn up the volume!
. It's put away now til spring ![]()

Kind of a crappy vid I did a while ago. I am actually going to be changing my setup in the future.

Is that the road paver cam in there Darby? It sounds pretty beefy! What all have you done to the motor since it's gone in the bird?
My only sound is the old retired wagon in 2010 before the wreck. It'll sound different in the 65 next year! The link in my sig is all I have..... Iron headed, 60245, RPM and Quad, Dougs 1 3/4 headers, 3" pypes w/X, race pros, and 3" tails.
