I install two 2.5 inch, center inlet quickflows on my 4.8 today. I feel a good amount of bottom end again, and great top end power. But the sound is amazing. Good low grunt from 500 to 3000 rpm. Over that, wow, it really opens up and pulls hard. Everyone that is running them around here are pulling there cut out off cause there is no difference with the quickflows to open cut outs.....

I am tell you now, you need to look into these mufflers...

how much did you pay for the two? listened to the 4.7L on the website and it sounded pretty good?

 

Almost sounds identical to my 40 series Flowmaster.

 

Go to the website and you can order them online. If not, message me or email me and i can get you a set for around $175. That will be in either size, 2.5 or 3". Email me if you need more info.....
