I have the extractor secondaries for a 20v and cat with cat sensor attached. They came from a 20v silvertop.
Don't need them as i no-longer own a corolla.
Also now have 2 mufflers for sale (had 3 but one sold).
1 is a straight thru muffler with a stainless steel tip. (inlet is 2 1/4 and outlet is 3" with mandrel bent internal) 3 weeks old - $80
Other is a canon muffler, stainless steel with titanium blue flame tip. Seamless welds(inlet 2 1/2 outlet 3 1/2") Brand new $120
