Ok Guys,

I'm about to pull the trigger on putting flowmaster on my JK. However, does any of you guys know the difference between 40 Delta and Super 40?

And lastly, for those who have this installed on their JK, does it drone on the highway going 65-70? I don't mind the aggressive sound, as long as it's not droning to the point where it gives you headache on long trip. I've listened to all of the flowmaster sound clip here in the forum, and i really like the deep sound. Just wanted one last assurance before pulling the trigger

Thanks in advance for the advice!

 

I'd like to know for I am in the same situation...

 

I'd like to know too!!!

 

I have a flowmaster 40 series I have no idea of what kind it is... the muffler shop just threw it on. As for as drone on the highway, I barely know it is there with all the wind noise. But start up and in the city it has a very nice deep tone.

 

Alright....that's what i want to hear ....i'm going to put this on maybe next week....still trying to find the cheapest shop

 

I paid $150 installed and that included relocating it underneath the drivers side and a tip.

 

great...that'll give me a good reference as far as price. I'm sure it's going to be more expensive around here....Everything seems to be expensive up here in CT
