Exhaust mods and MPG

**COOKZ32** · 02-16-2007, 08:17 AM

I have an 07 SRT Charger, and was hoping to get some feedback on what the effect in relation to MPG other's are seeing after removing the stock exhaust system, and changing to one of the available after market cat back exhaust mods. Please let me know if your MPG improved or not, after adding a cat back exhaust system.

I did not buy the car because I was expecting high MPG numbers. It just has a small gas tank and I would be bummed if I had to stop for gas more often.

My 06 Mag RT did not respond well to catbacks and lost nearly 3 mpg after install, however the SC tuner brought the MPG back to the original numbers.

I sure like the sound and looks of aftermarket exhausts.

Please take a second to post your findings. Thanks in advance!!

Dan

My srt went the other way of your rt, cai and cat back exhaust seemed to help mpg, the b&g s2 knocked it back to "stock" mpg on regular mixed driving....driving it hard still only brings it down to 17.5mpg at it's worst with a heavy foot
