Re: 572 update
Is that cross pipe after the headers sold aftermarket or did you fab it?

Re: 572 update
I like magnaflow.... you dont get that metal clanging sound with the straight through design. Should have a deep tone to it....

Re: 572 update
Magnaflows are pretty mellow (maybe not on that engine ) and get VERY loud under heavy throttle. No resonation with my magnapaks and no crossover.

I just finished my BBC502 swap and I went with Magnaflows instead of my Flowmasters that I had on the truck before the swap. So far I'm very pleased with them they're not nearly as loud at idle yet they still have a very nice deep tone to them. Once you get on the gas they come alive with a nice deep rumble, and there's not nearly as much drone in the cab. I'm not sure how much sound difference there will be between a 572 and a 502 but they're perfect for my 502.


Did you ever figure anything out on the upper radiator hose? If not I may have found a solution.

They sound pretty good at lower rpm but I'm not too crazy about the sound under heavy acceleration/high rpm. However, the performance increase is usually worth it. They flow significantly better than flowmasters. Your basic turbo muffler is like 50-60 cfm on 2.5" pipes, the flowmaster 40's are about 105 and the magnaflows are like 160

Re: 572 update
well I hooked up the power steering lines, then I hooked up the brake lines to the master etc., I installed a summit swivel thermostat housing and flexible rad hose for now, and also slapped in a K&N 3 inch filter.

here are some pics

Re: 572 update
Well got the truck ready today to be sent out to the body shop, Don't get excited, it's just having the frame straightened, we noticed the frame rails where a little tweaked on the back.

I just took a few pics, I'll be out of town for a few days so no work will be done this week.
