Volant & Gibson Installed - Not too exciting
I should know better by now, as I have changed exhaust and intakes on many trucks over the years....similar results!
I bought a 2013 Overland Hemi in march, and I love the Jeep.
Being a gearhead, I knew I could not leave it alone.....so, I added the Volant Cold Air Intake for $275. The result was no more than a moaning sound from the engine. Little if any performance increase, and NO increase in MPG....this was really expected, but it was installed in anticipation of the exhaust, hoping to let it breath better.
The I looked for an exhaust, and was absolutely amazed at the cost of the cat back systems available. $1500-$1800 is incredible!!
Plus, the reviews indicated droan and vibrations, etc.
So, I opted for the $360 Gibson axle back mufflers to replace the resonators. I just wanted a richer, and deeper exhaust tone, again realizing there would be no power of MPG increases....
I spent $100 to have the old units removed and the gibson units welded on. No that I have had them on for a couple of weeks, there has developed a nice mellow tone upon startup, until the rpms drop to idle. then it is as quiet as a church mouse.
Inside the vehicle there is a sould that allows you to hear the engine, but it is certainly not what I was hoping for....instead, it is a cross between a moan and a modified ricer muffler, but very quiet. It's not irritating but not good either....difficult to describe.
So, after $600+ spent, I can hear the engine run, and it sounds cool on start up.....no increase in power or MPG. It does sound great under WOT, but it did before I spent the money....now it is LOUDER!!
When will I ever learn.
I guess I could spend the money on something to replace the main muffler, but everything I've read indicates that that it would either be super loud, or drone or both.....so, I'll keep what I have and hope that over time things will get better....
In the meantime, I hope this will save some folks from wasting a hellofalot of money for nothnig.....ugh!!
