Installing 3 inch true dual exhaust

[87oldscutsup]

Was wondering if anyone has ever put a 3 inch true dual exhaust on a 87 oldsmobile cutlass supreme with 3 in headers. And if they had any problems connecting the pipes to the headers. Any info would be greatly appreciated. Thanks.

What size engine are you running and brand?

It's just the stock 307. It's a pypes ss style with x pipe and headman street headers.

Go with a smaller system. 2 1/2" at the largest.

Would the 2 1/2 still fit the 3 inch headers?

Do your headers look like these?

I wouldn't have even went with 3" collectors on a stock 307.

I have 4" over the axle and out like a GN, 3" no problem

So if I use these I can still use the 3 inch exhaust or should I use 2 1/2
