Planning out a new exhaust system

[427LX]

On my exhaust setup I came up with a merge chamber between the 3 inch pipes that lets me choose between an X flow or
fully separate flow.
What I noticed is when I want the nice rumpity throaty sound I swap in the divider plate which has little if any crossover flow.
Seems to give a bit quicker throttle response.
Switching the plate to a flat plate gives the full crossover X-flow and smoothes out the sound and seems to give a better pull thru the RPM range. 
Best of both worlds when you can change it around!

Does anyone know if Flowmaster will sell the pipes to their kits separately?  They have a 2.5" stainless kit with an H pipe that is exactly what I'm looking for but I don't want the mufflers.  I reached out to the company but haven't heard back yet.

Wanted the back part of the Flowmaster kit for Fairlanes since the mid-section wouldn't fit my convertible chassis.  I talked to a sales rep and he said they can't do partials unless (wink wink) I was buying repair parts for a system that was damaged in an accident.  Ended up selling me the tailpipes and hangers separately.  That was several years ago, so they may have a different policy now.  The easier option is to buy the entire kit and sell the mufflers on ebay.  You'll lose a little on the mufflers, but you may be saving over the individual piece part price.

That's what I was thinking.  Especially if going through a seller like Performance Peddler.

That is certainly an option, but another option is buying 5.0 Mustang tailpipes, mandrel bent, and then cut the exit to fit.  I haven't don it, but friends have.  Use the mufflers you want and then buy a couple J-shaped mandrel bent pieces to make your intermediate pipes.

I have found, with a big cut off saw and a little welding, you can make a much nicer setup than a "fits-all" exhaust and it's cheaper.
