whats the best way to do side exhaust?

Just get the kit. I know cause I already tried it. I have the flow path(very similar to FM) and took it to the shop so they could custom bend the piping and it ended up sounding like ass. To me, it sounded like a camaro. Too many bends in such a short distance. Wasn't worthethe hassle to me. I'm not sure it this will work, but try it with a straight thru muffler, that way it'll only be one bend to the outside.

I second just getting the Borla kit if you are going to do it. Coming from manufacturing, if grade of materials is equivalent, mass produced is almost always cheaper than custom. I did however cut off the Borla tips as I didn't care for the dual cylinder look and I had the shop weld on a single wide oval to fit within the side skirt opening. Here's a pic.....

Do you have closer pics of it?

These pics suck (you can't really see the skirts cause of the glare) - but....here you go:

I'm not gonna lie though - the job as a whole SUCKED.

Borla's kit isn't bolt on and go. I had to get one of the side pipes bent to fit up into the exit hole.

The skirts are horrible - I had to get them custom cut, painted, grind down the front - and have to fill in the small space - but the pro is that the kit looks badass - I love the skirts.

I don't now if I'm too keen on my exhaust coming out a bit, but its growing on me - I kind of liked Rio's where the tips just came to the edge of the hole, and not past it. I'm sure he'll post pics and you'll know what I mean.

AS FOR BUYING:

Don't pay more than 600 shipped for the kit. I got it from Borla on clearance and I believe ford should match that price since it's no longer continued. (it's still under warranty though)

If you don't like the skirts I know Cervini's makes them pretty much the same without the "SVO" badging, and they're urethane so they're much easier to work with.

Good luck!

Oh and one more thing - if you want to do custom tips like above that's not a bad idea, borla sounds awesome without the tips on, with them on they're a bit quieter - you can always make custom tips instead of dual and they will sound sick.
