Muffler / Exhaust

[cheetah2390]

After reading through this thread and seeing the innards of the stock muffler, I decided to replace mine. I went with Magnaflow #11225. Had it installed last week for $111 (muffler and labor) at Modern Automotive Performance (employee pricing bc my brother works there). I’ve had it on for about 300 miles. It’s mellowed out a bit, kinda loud if I step on it. Not much if any increase in HP. I will report back on MPG.

I'm also making a switch. SpinTech makes a 16" [body] offset inlet, dual outlet muffler. I ordered it in the quietest version. (Sportsman XLP)

My shop is going to add resonators before the stainless/chrome tips. They'll point straight rearward vs. being angled down like factory.

Hopefully, I won't regret the change in sound! Hoping for a big of responsiveness out of the deal. Maybe another mpg too.
