instead of 30whp, you might get 28 or 29, no dyno is going to pick out the difference. A catted aftermarket downpipe might be good for about 20whp, so the resonators are definitely going to be much much better then the catted version.

Okay cheers, that's what I thought too. It does not look like a restriction. Is the 30whp gains with a tune? Maddad are claiming 10whp for their resonated midpipes. Do you think catless downpipes + maddad midpipes is good for 40whp or am I dreaming?
