1999 V6 Mustang True Dual Exhaust Systems


I know this has been discussed to death, but I'm having some real trouble finding a true dual exhaust system for my 1999 V6. At least, one that isn't Pypes brand. I've read about dual exhausts provided by Flowmaster, MAC, Magnaflow, Jegs, Borla, Bassani, Pypes, Thrush, and Spintech. I wouldn't mind an H, or X pipe. But it must be catted. And it would be great if someone could recommend some shorty headers that bolt right up to them.

So far, the only "true" dual I've found is made by Pypes, but I'm not a huge fan of how raspy it seems. If someone could direct me to a site that sells a "true" dual exhaust system for a 99 V6, I would be much obliged. Again, I don't mind H/X pipes, but it should have 2 pipes running all the way down, from the headers to the mufflers. Thanks in advance!

What you do is buy an H pipe adapter, and then bolt up a GT catback.

Shorties are a waste of about 200$

That allows any GT catback to bolt up while keeping your stock cats.

I don't know if that LMP is a copy or is a Pacesetter pipe, but that same adapter is available through Summit Racing as well. You cut the pipes off at the end of the factory cats, and weld that pipe in, then you can run any GT cat back system.

The BBK ceramic shorties are nice parts, I have a set on my 01, but like ESG said, performance wise, they are useless.

Hey, Great ideas, guys! But just wondering if I would need a gt style bumper to accomodate the tailpipe tips? Finding one in Electric Green is gonna suck, and I don't really want to mod the body if I dont have to.

Also, are there any headers that anyone would recommend for our sixers? Longtube headers that would work with the gt catback adapter previously mentioned, included. I want a deep rumble, and I understand that headers help with that, even if they don't provide the utmost in performance gains... Thanks again!

if you go with longtubes you dont need to even worry about the adapter.. then youd just buy a shorty midpipe and replace the entire exhaust all at once
