05-09 Mustangs SLP Loudmouth Exhaust system

75

Asked by Apr 12, 2013 at 11:06 AM about the 2005 Ford Mustang GT

Question type: Car Customization

I'm looking at the SLP Loudmouth Exhaust system, and i've seen videos online, but they're only videos...
and what i'd like to know is if anyone has had trouble because they were too loud and resulted in getting pulled over or if the police said anything to people about the custom Muffler Delete system.
any input about these would be greatly appreciative, because the sound of this exhaust sounds legendary, but i dont want too much attention from the PoPo.

Thanks

Are you going to keep the catalytic convertors with that new setup?

Yes. I plan to at least. I don't want to do too much to the car. Just want to have a nice exhaust sound. What do you think/recommend?

My Grand Am has a stainless steel SLP cat back exhaust system. My daughter got pulled over once for have a non-OEM exhaust but I think the sheriff was looking for DWI's. The SLP was discontinued for the GA years ago. It was louder than the Borla cat back. In the winter months, I install resonator tips to reduce the drone on the highway.

I live in New Jersey. So I don't know what to expect but I know there's going to be an amazing sound coming from the car.

Depends on your state and how much of a prick the cop is .what I don't understand is why they pull cars over but 1 loud ass Harley you can hear for blocks get nothing. Think about it ,it would probably take 3 or 4 cars at high rpm's to equal 1 cruising Harley-Davidson

I have longtubes, catless mids, and the SLP LM1 on my 5.7L GTO. Got pulled over once and was complimented on the exhaust actually. I live in WI though.
