Has anybody had any experience with the Edelbrock cat-back system, or the Edelbrock RPM series muffler? How does the sound and power compare to Flowmaster? I am planning on getting Edelbrock TES Headers, a high-flow cat, and the Edelbrock cat-back. Does anybody have a setup similar to this? How does it sound and perform. I am looking for the deep, throaty muscle car tone, will this provide it? Thanks.
