Mangaflow bad review - going back to stock
Well I went ahead and slapped on the Magnaflow #14220 today...
There are multiple problems with this setup:
1. It sound like a Chevy S10 or a Ricer that is bogging in the low RPM's
2. From the inside of the Cabin there is a huge droning sound. At 65mph in 6th gear you would be lucky to talk on the phone.
3. This muffler really needs a resonator to block the sound on the lower RPMfs. However adding one will make it sound like a ricer even more (ring ding ding ding ding bog).
4. Loss of bottom end torque. Besides the awful sound, is the first thing I noticed. I was no longer being pushed back in my seat on take off (a sign of a loss of low end torque, which was my biggest fear).
Since I will have the stock system put on tomorrow, I am guessing that this thing will cost me a total of $300-$350 of just wasted money.
I know others may feel differently but I really do beleive this modificatioin is a mistake and should be avoided. Wait for someone like borla that is making an exhaust specifically for our car rather then going this route.
hope this helps,
