Exhaust that doesn't pop?

Hey guys, i'm new to the forum just have a quick question i hope. i've got a 07 GT, i want to put an aftermarket exhaust on it and have been combing the internet and youtube trying to find and exhaust that doesnt "pop" or sound like a backfire when you rev it or let off the throttle. not doing a full exhaust just mufflers. i think it does this due to the lower back pressure and it seems all the exhausts are 3" diameter or larger. I would appreciate any suggestions or remedies for this.

I already tried a pair of pypes muffler deletes and it popped bad. So I figured there would be a muffle set out there that didn't pop

I don't think so. Every 05-09 I hear with aftermarket exhaust does it. I didn't know if someone out there had a set on there car that didn't do it.

When u let off the throttle you don't get like a poppy crackling sound. That's the best I can describe it.

Re: Exhaust that doesn't pop?

All most any performance car will pop under the right conditions, and the way you drive the car. I bet you down shift to slow the car, that will always make it pop. So just get something you like, i run stock Ford Bullitt mufflers, and i can make it pop if i want.

Magnaflow 3" magnapack cat-back exhaust gave my car a deeper tone while keeping the popping to a minimum

No I don't want to get rid of the nice sound just the popping. I think it sounds cheap sorta like some young kid with an old 350 chevy pickup who decided to cut the mufflers off.

The JBA sounds really good

I don't think you are going to get rid of the pop to be honest

I was checking out some clips of the JBA's and they sound pretty good I may go with them. And to "onesick07" I just don't wanna be that d-bag driving around with a stock car and an obnoxious exhaust.

Mines far from stock this is the 5th one I've had and they all sound the same. Unless you go with an over priced exhaust you WILL NOT get rid of the pop it's the exhaust tone they are known for!

I'm not here to bulldog back and forth about what you have or had. This isn't my first either and there are obviously exhaust out here that don't other people have them.

---------- Post added at 01:35 PM ---------- Previous post was at 01:34 PM ----------

And the fact that yours is "far from stock" you probably have more than enough back pressure to flow 3"-4" pipes thus it probably does sound good

---------- Post added at 01:37 PM ---------- Previous post was at 01:35 PM ----------

Correction* your pushing enough pressure that the lack of back pressure doesn't effect the sound

I know I'm a bit late on the draw here, but I can explain the popping.

Long explanation:
They are lean-condition pops. When you let off the throttle, your motor experiences a low air/fuel ratio and causes the popping sound.
It is in no way harmful to your motor, in fact, it happens every time you shift in a stick. It's just part of the exhaust system.
The catalytic converters do wonders in suppressing the sound (listen to a catless GT rev and you'll notice it has wicked loud pops - ESPECIALLY if you have an x pipe). Longtube headers and a catted H is the only thing I've noticed to decrease in the popping.

Short explanation:
Exhaust just pops: every car I've owned pops. Corvettes, Mustangs, trucks, etc. It's the nature of the beast.

Yes anything built or with an aftermarket exhaust will pop. I was just wondering if any aftermarket exhaust manufactures remedied this. Your factory stock cars u can rev the hell out of and won't pop.
