Magnaflow muffler question
Has anyone replaced the factory single in/dual out with a Magnaflow single in/dual out with any success. I would assume it would have to be a cross flow design due to the setup.
My other thought or idea would be to use a single in/ single out setup like I had on my 89 Formula. This should allow it to be a straight in and out setup?
What is everyones thought for the people that are planning on keeping the stock routing, please dont say or suggest go headers with true duals as I hate how the trual duals look and dont want to sacrafice the ground clearence for them. I plan on doing headers this year but am going with Mac midlengths as I want to keep it tucked up high and dont want to spend a fortune on a set of good/great quality headers and see way too many post of issues with almost every full length header on the market right now.
As for your question, I have replaced the factory muffler with a magnaflow one, it worked pretty well. Just get the Magnaflow single in dual out muffler and you should be all set. The only thing was the piping was the factory size, so I didn't gain anything there.
Single in single out is also an option, but you will then only have one tip/exit, so it might look weird from the rear. Performance should be about the same at your level.
I talked to Magnaflow and they said their single in/ dual out flows the same as their single in/ single out. So I guess I will try to source a single in/ dual out here soo.

You gotta be getting some sort of kick back....

First thing on start up I noticed was it was alot quiter than the 2 chamber Flowmaster I had on there, even with me not having cats it is alot quiter at idle and just normal driving.
Under WOT it seems to be a little quiter than the Flowmaster as well but still has a nice growl to it and is not too much more quiter. We will see how it does as the packing breaks in on the noise. Does make conversations easier in the car now though.
I looked at the Magnaflow right before they welded it in and had an idea of what I thought I would look like in my head and my idea was exactly how Magnaflow built it. Should be less restrictive than the flowmaster for sure.
