Modified Exhaust

Alright, so I have a 2010 V6 and my dad seems to think that Modifying the exhaust goes against one of the emission laws, the thing I would be doing is going from single to dual. Is this true? I was going to try and get the Pypes true dual but the guy at the muffler store said it was illegal to modify exhaust. Help would be nice


Performance Mods- Dual exhaust (Straight pipes to flomasters), BBK CAI, 93R Bama Race Tune

Appearance Mods- 20% Tint, tinted lights all around, 1/4 louvers, Black A.M. 18" Rims, Black Boss 302 Style Striping, Black Rear window louvers.

you're violating federal law if you remove the catalytic converters.. however just removing the muffler, and splitting the midpipe to make duals is not illegal by any means

The rule of thumb is anything after the cats is fair game to modify.
That being said, if modifying the exhaust was illegal, you would have to lock up 99% of the forum.

Check your local laws instead of listening to the lawyers on this forum. There are a ton of things that are illegal to do to a car but most of the time either the cops don't know or care and people never get hit with the fines. There is no rule of thumb, only rule of law.

Federal law makes it illegal to modify or remove any emissions control device on a car. The fines are high, but enforcement is low.

State law adds another layer to the motor vehicle laws. Most likely it is not against the law to do what you want, but if you pay close attention to most descriptions for auto parts on performance websites most clearly state off-road use only so that in the event of a ticket they are not responsible, you are.

Its not illegal as determined in the prior posts but I would stay away from the persons who told you it was (accept your Dad) and look into something other than the Pypes set up. That is a fantastic car you have and you would be doing yourself a favor by contacting your local Mustang shop and working with them to appropriately modify your exhaust in a way to compliment performance and the car as a whole. Borla products would work nicely. Ford Racing has a GTA 4" (as opposed to the 3.5" to stay away from)tip package to put on.

as others said a local mustang shop would be a great place to start and as with many things we do to our cars laws may be broken but they probably wont be enforced (like the 5% tint i have on my rear windows). As long as u leave the piping from the manifolds to the cats you should be fine.

Show: Smoked everything, cobra front bumper, gt rear bumper, rear decklid and lower valence blackout with black mustang letters, 5% rear front 15%, black 98 Cobra rims front, 95 Cobra R rear black with chrome lip, black scoops and spoiler and exhaust tips

Go: CAI, True Duals with flowmaster super 44's, Bama Tune, full suspension (lowered, 8.8, 4.10s, UCA, LCA, springs, CC plates)

modded exhaust

I'm about to do this myself. I looked at the Pypes stuff, my guess is you were probably trying to do an off road kit. They do sell full systems with cats just a little more expensive.
