Delete as in pull them? I got straight pipes and it is great. Sounds amazing and looks cool when up on the lift. Not sure about performance, maybe since the back pressure is off a slight loss but nothing noticable
I'd say for a v6 leave the mufflers. Get some chambered mufflers and you'll be happy the sound. Since you have the 05+ you could get axlebacks and save some coin on a full exhaust system.
Mines a v6. Sound incredible but yeah it took me weeks to find somewhere to inspect it and pass it. Eventually had to find the slummiest, shadiest place to go
So I've been trying to think if I should straight pipe my mustang. I've been reading about some people saying you can lose power or torque.....So I took the chance and had the local muffler shop straight pipe my mustang. Let me tell you that it sounds awesome!!!:headbang: I don't feel any power loss or torque loss. The only thing I can say to those people that say you lose power or torque is that the car is louder and when its at 2k you think its at a higher rpms so you shift earlier..if that makes sense to you guys.. thanks again to all you guys.

Exactly. I short shift all thevtime to keep noise down so I don't attract unwanted police attention. But I feel nonpower loss either. Good for you going straight pipes. Join the club
Pretty sure its a federal law making it illegal in all states, some just don't do emissions test such as AL. But if you get pulled and they happen to check for cats they can, not saying they will, give you a ticket.
Correct on the new cars the resonator is exactly like a muffler. As long as you have the resonators and the cats your good to go, that's why you can by the muffler delete or the GT. never looked at the V6 exhaust but if it has the same setup then no mufflers is ok.
I don't understand why so many guys want to take the cats off thier cars if they want to do that why not just buy a race only car in the first place I understand the sounding good thing but why go to such extreams om a street car , I know I will get flack for this,but I am just trying to understand why.

thank you!
I ask the guy at the muffler shop if he could give a quote on a recommend full exhaust system and he told me that you don't need it. The new mustangs come with a x pipe and taking of the mufflers is really smart...

I agree with everything you say, my brother also did this.the only problem with straight piping a v6 is once you get past 3500 Rpms it sounds like a loud ricey fart. It really only works well on high performance v8's (gt 500, corvette, g8gt etc....)
I have BBK headers and a BBK catless x pipe with them. Today I installed a Magnaflow competition series which has resonators in place of the mufflers and added some parameters to my tune for them. I have a decent power gain up top and it sounds AMAZING. I'm not even kidding, it sounds like my friends 5.0 with a catless x and magnaflow street series. Just a bit louder. It really does sound like a V8 now. I'd recommend it.
