71 302 auto coupe dual exhaust kit

[bley49]

Good evening everyone,
Im trying to find an as bolt on as possible exhaust kit for my 71 302 couple I'm running stock headers and need the dual pipes to the exhaust tips. I found the scott drake kit but i don't want stock sound.
This seemed like the best I've found

Thank in advance!

That kit doesn’t include mufflers. Are you trying to find a kit you can install yourself?

I was going to add the mufflers, I'm having a shop do it but I still want the most easy install for them

Which kit is stock diameter 2" or 2.25?

The NPD 302 kit is a 2" bolt on style, you need to add the H-pipe and a hanger kit as needed. The H-pipe fits factory exhaust manifolds.

If you want to use different mufflers, then just buy the individual pipes

You can go to the kit way, or you can have the muffler shop just give you a quote for building the system you want.

Thanks for the links I got the H-pipe to the tips!

Yeah, that’s what I bought….installed it by myself, with a little difficulty…it fits, sounds good. A couple of tips…if the H Pipe doesn’t align just right, use a ratcheting strap to flex it into position…and if you test without tailpieces it will sound like crap and make you cry…add the included tail pipes and it sounds great!

Being that you are using common muffler shop bends, you may want to go up to the 2.25 or 2.5 diameter. That concoction of multiple muffler shop bends will reduce your overall exhaust flow 30-40%. while mandrel bends reduce nothing. Very few muffler shops have mandrel machines, and the pipes would either have to be ordered that way or bought in pieces, the way I order them. If you plan on keeping it 100% original any of them are fine. If you plan on adding some performance to it, you might want to start with your exhaust flow. Now would be a good time to add headers.
