850 exhaust question

[PrestigeC70]

I purchased a Turbo Muffler from Pep Boys for about $20

that so-called 'Turbo Muffler' you purchased is most likely a chambered design with baffles. From what ive been told, turbo cars need a free flowing muffler without the chambers or baffles. Good inexpensive examples of free flowing are glass pack mufflers like cherrybombs.

2 things happened, My car immediately became a terrible car to drive. No get up and go.

My guess to your cars lack of speed/torque is you didnt reset your cars computer/ecu (disconnect battery for 10mins). Again from what ive been told, resetting the ecu will allow your car to notice the exhaust change and learn/adjust to the performance gain.

The other was the noise, I know that's why you add a performance exhaust but it became too loud. My wife won't drive it any more. My son says it sounds cool when idling, but even he doesn't like the drone at freeway speeds.

Adding a resonator or 2 will reduce or eliminate the drone/hum. I think you should swap that turbo muffler for a glass pack muffler, its moderately loud but theres hardly any drone. But if your sensitive to resonate frequency's adding resonator is the way to go.

Wow. Thanks a lot. The "newly approved by California" catalytic converters are selling for around $220. Doesn't make the exhaust such a deal anymore

Iam in cali too and have a $100 magnaflow race cat. What ive done is have a shop weld flanges on my stock cat so when i have to smog test my car all i have to do is remove some bolts to replace the race cat with the stock one. Ounce the test is over i remove the stock cat & reinstall race cat. works for me

I'm getting this same exhaust. I believe that section between the two mounts is a cat converter.
