Exhaust, Flowmaster 40s vs Magnaflow
Ok, I know it's been asked 200 bil times, but I am asking at again.
I just sold one of my AK47s, and have a few bucks to spend on the Mustang. Exhaust.
The two I am considering most are Flowmaster 40 series kit from NPD, or the Flowmaster X pipe system from a local dealer here (same kit NPD has for $650 or so, guy is selling for $315)
I have never heard a SBF with the Magnaflow system, and youtube doesn't do any audio justice. Anyone have any recommendations? I know that 40 series start to "drone" but this isnt a Daily Driver for me, few times a week at most, so I'm not terribly concerned with that aspect of it.
Whats the difference in sound and performance between the two kits? Difference between h pipe and x pipe?
Thanks alot, everyone.

I have a magnaflow on my 361c.i. sbf, and here's the deal. Magnaflow is a bit quieter than flowmaster at idle. At WOT it's plenty loud though. However, Magnaflow performs better by a few horsies. Flowmaster's sound is very common so I like the fact that I can lie about my 361 being a 302 with my magnaflow.

Not a fan of X-pipes on sbf's. In my experience, they tend to have a weird high pitched tone to them. Basically, they don't sound right.
That said, I much prefer Magnaflow mufflers over Flowmaster 40's. A nicer, more even tone. Less blatty and raspy than the Flowmaster 40's.

If you like the sound of a high revving motor, choose the X. If it's the rumble that has more appeal, pick the H.
I'm afraid that I can't offer any useful opinions with respect to anybody's complete kit though - I've always used either straight-through or "turbo" mufflers bought on the basis of specs and price (rather than name) and fabbed up the rest from straight pipe and mandrel bends.

This video clip is the 2 1/2" exhaust with series 40 flowmasters. I hear the Magnaflows are better but more expensive. You should be able to afford them though since the run of the mill AK's are selling anywhere from $800-$1000. I'm sure it's a Romanian you only paid $300 for last year

Got 1k for it, paid $500 just 6 months ago.
