Hooker Header Back ??
Considering installing the Hooker header back system 16521HKR on my 78 L-82 along with my existing Dynomax super turbo mufflers. The Summit site has an application note saying “Must use 2 1/4 in. offset inlet/center outlet muffler.” My mufflers have an offset inlet and offset outlet. Any issues with this setup. Will the 16521HKR have any fit problems when paired with a set of Jegs headers? Anyone running a similar setup?

After more research, here's some links the depict the difference in offset's.
Offset inlet and centered outlet.

Offset inlet and offset outlet. (What I have)

I haven't confirmed it but seems the offset inlet/offset outlet may not work with the Hooker 16521HKR system. It seems to be designed for the offset inlet/center outlet because the inlet is offset on the other side. I could flip the ones I have but the outlet move further out... Confusing

I JUST installed this like 3 weeks ago..it was a PITA. It is a noice setup after re-working it and cutting parts short...and reversing the standard muffler brackets on the mufflers.. The price is right but expect to be in the garage for at least 4 hours getting things to fit.

BTW.. I AM indeed happy with the final results and it does clear all parts of my frame / monospring.. Out of the BOX... That would never have happened.. the price is right but my time was perhaps not worth it....

My experience was exactly opposite of the others. My brother and I put this system in my 76 in about 2 hrs. Cut the flanges off the front 2 pieces so they could be adapted to my Stan's Tri-Y headers and cut a piece off of each side in the rear to mate up with my mufflers. Fit great and tuck up under nicely!!

Sorry bytor, I do not have any pics of that little adventure...
I cribbed the car up on 4 points just enough to get the new header under and in the driver's side. It didn't leave much room for us working on our back with the exhaust so I didn't take pics.
It took us about 1.5 hours to put the headers/plugs/wires in and get the engine compartment back together. Then another 2 hours for the rest of the pipes. We were quite happy with the whole set-up and time it took.
I could probably take a pic or two but it'd be a few days. I'm onshift working 12s at the plant right now.
Sorry I couldn't be of more help other than an opinion......

I bought the hooker exhaust that was designed to fit the hooker comp headers. It was not even close to fitting. They also eliminate the factory exhaust mounts and use a goofy system of brackets. I sent it back. The hooker headers fit excellent, though. I then bought an exhaust system from Allen's that was really nice.
