What made you choose this particular product?

quality

Is this your first time buying from this brand? Did you consider other brands?

Was it easy to install? Any installation tips that will help others?

chop/swap with the 50s series muffler. slightly more forward for location. local muffler shop did the work

Once you've had a chance to use the product, did it meet your expectations?

yes

Any additional comments?

the 50s series was not enough to control interior resonance between 1500-1900 rpm. I think the combination of the long tube header, resonator removal and over larger pipe diameter collectively contributed. It is much much better now, I would say the ideal combo for a full exhaust option (not a dual setup). The additional baffling and size of the 70 series absolutely did not remove any of the performance gains already experienced. So no worries there.
