Edelbrock's site has outdated information and pictures of it's catback system. The system designed for 5.7 cars does indeed have a 3" i-pipe, and here's the proof:


I ordered the system last week. Another inaccuracy is the image of the tips... they are long, polished tips. I won't be using them, however...

 

I just found this out the other day too I always thought it was smaller but sure enough i measured it, and to my surpirse it was 3 inch....I no longer have the edelbrock muffler though I swapped it out for a B&B

 

Im in need of a 3" Intermediate Pipe and preferrably one that has a seperate Over-Axle pipe 3". Smooth mandrell bend referred. I have SLP 30005C Headers to a 3" Y-pipe to a 3" test pipe. The rest of my old Dynomax ST 2.5" kit from the 305 is whats left. Only a FMaster 3"in and 2.5" out is the rest. Ive seen the D.Max sell the seperate 3" parts, but was wondering if there was any options or a good used I-pipe/O-A pipe someone no longer needs. No rusties PLS.
