I like them for fender well headers but under the car with no tail pipes you choke on the fumes...there load...pretty restrictive...my son bought side pipes for the car and the fist thing i did was make a set of glass packs for him using a set with 3 inch in and out with a 3.5 inch case..They breathe quite well and have a deep tone....

Those header muffler look like they exit under the car right at the B pillar, no wonder you're getting fumes in the car! You'd need to extend them to exit right in front of the rear wheel... That would help, but may still get some fumes inside at times (like sitting still and idling) due to the back doors being right at the front of the wheel well. Good door seals help, but probably wouldn't keep all out.

I had made a video showing the massive restriction that the org. glass pack that came with it had...2 inch inlet and a 1 1/16 core for 52 inches....The way the new mufflers are swedged the inside diameter stays constant and i have 36 inches of perforation surface..3 inch in and out...plenty of surface area to absorb each exhaust pulse at lower rpm`s but free flowing at upper rpm`s...and with a 3.5 inch case they fit nicely beside the shields...It`s hard to beat a simple glass pack

Doors have never been off my wagon! I stripped them down when rebuilding the car and painting, but since they closed well and were gapped pretty good all around, I didn't want to loosen the hinge bolts. Got lucky, don't see that real often on a 40 year old car (when I built it in 2003). Still that way -- even the driver door hinges are still good!

You've done a great job on that Concord, by the way!! Know you can't wait to get it finished.

Engine done...I will hook the tran`s back up tomorrow..

Anthony, I put the 304 in the wagon last week (by myself) the motor mounts gave me grief till I took the p/s plate off the block then lowered it onto it when it was in the crossmember. The p/s head would up dead against the firewall ( my BIG pry bar remedied that situation. Got the trans in by myself also but the p/s header slipped out (couldn't get it back in so instead of playing with the motor mount I just removed the strut bar and rear strut bar bracket, it went right in. Today I fitted the shifter cable along side the braided trans lines,and cable for the kickdown. Like 10 # of you know what in a 5 # bag. Next the exhaust system and the trans dipstick.. Everything is a fight with not much room for all the things on the d/s. Luckily the dipstick tube didn't give me too much grief.All of this in a 20' x 10" garage.
