Default SLP Loudmouth check engine light

Will the SLP Loudmouth axle-back exhaust for sale on www.AmericanMuscle.com cause any check engine lights to go off?

I bought those exact LoudMouths. Put them in myself and have had no problems in 3+ months.

Enjoy!

no. the exhaust wont throw a light until you start messing arround with the cats. some people talk of high flow cats causing it, (had mine for 6 months and no light) but mainly removing the cats and using an "off road" x or h pipe with no tune or mil elimators is what does it.
