That can happen. It depends on the size of your exhaust pipe and how much/little back pressure you get without the muffler.
 
That's why I tell people there is NO power in a muffler or a free-flow air filter. Usually you get the most power by removing both of them, so they can't "create" horsepower, then can only release a little more that might (or might not) be trapped in your engine.

#71 of 78 99 Cavalier Cold Air/T Body Spacer Problem by mrcav99

Jun 08, 2008 (8:01 pm)

I have a customer with a 1999 Chevy Cavalier 2.2. A Cold Air and throttle body spacer
was installed and now when you accelerate hard from a rolling start the temp gauge drops to near zero (acts like a vacuum gauge dropping to zero under full throttle). Does anyone know what could cause this?
 
Thanks, Ben

#72 of 78 Higher flow muffler, Toyota Highlander Hybrid, improve MPG?? by sebemismnusa

Jun 10, 2008 (1:46 pm)

What I have: 2006 Toyota Highlander Hybrid with front wheel drive, 3.3 liter 6 cylinder as found in many Highlanders.
 
Would a higher flow exhaust system, for example a Flowmaster muffler series 50 or 60 help, in addition to removing the twists and turns in a Highlander's exhaust system ? I have not found any catback systems for Highlanders. Would I really have to replace the catalytic converter, too? Or how would I know if the stock catalytic converter impedes exhaust gas flow? I also assume there are EPA regulations on catalytic converter replacements, too.

I am looking for any feedback on after market muffler systems, like Speedtech or others. I have visited two different websites for two different manufacturers which include video/audio bytes of the products as installed and driven. Any dos or don'ts or advice? Performance and sound seem to be the "plus"
