Will any shorties bolt/weld up to the stock ypipe on my dual cat 305?

 

None that I know of, that's why you have to buy a y-pipe.

 

Well, anyone make prefabbed ypipes for dual cat cars?

 

Or can they make one before I do an install of headers, since it is 12 miles from my place to the nearest exhaust shop...

 

It's best to have one fabricated at the exhaust shop for this dual cat setup. It will fit the best and perform well.

Don't be shy to drive the car with open headers or exhaust to a muffler shop, that's normal. If a cop hassles you just explain where you are going. I've done this many times and never been pulled over. Just drive very slow if you can, safely.

BTW, the car quiets down in your OD gear quite a bit.

Just my .02 cents worth.........

 

That makes sense...Thanks...

 

Be careful driving with open headers on a cold day. Unless it's warmer than 50 degrees outside, you stand a good chance of warping your exhaust valves.

 

Yeah, most muffler places can fab you a y pipe, but like he said, be really careful driving with open headers. You'll want to secure all wires to be very far away from the headers. They are quite a bit hotter than your stock exhaust manifolds, and will burn through your spark plug wires, your temp. sensor units' wires, etc.
