Exhaust systems/mufflers for 87 T Type with Olds 307

[88cscb]

the flowmaster you want to look for is the cross flow or "camaro" style. 80 series i beleive it is for F body camaro/firebird

Now 307Regal when I look for that flowmaster muffler what do I have to look for? Such as specific sizes and whatnot.. Thanks for all the replies guys!

It should be 2.25" inlet and 2.5" inch outlet if I remember correctly.
The muffler is set up like so:

I had mine put on at a muffler shop. The funny thing was, the car was the same volume when I started it up. :lol:
As it turned out, my catalytic converter was doing most of the muffling.
What you can do, though, is buy a high flow catalytic converter. I was going to do this myself since I still had all of the emission controls in the car at the time, but my dad advised against it since I really didn't need to be spending the extra money.

Hey. Those headers you posted are for the small block Chevy. To run that exhaust you will need to modify the stock crossmember or buy a new one made for true dual exhaust. I would call local muffler shops and get a quote for a compete true dual exhaust . They can flatting out the pipe or bent the pipe around the stock crossmember. True dual exhaust is the only way to go. Heres a few headers for your Olds motor in your Buick.

Gonna go to local shops and see how much both of them will cost, most likely gonna go with true duals if it's not a insanely high price. About how much is a modified crossmember?

Thanks gonna go around and see how much each would cost total. What's done to your Regal?

You would have to take your crossmember to a welder to see what they would charge. I would run the stock crossmember and let the muffler shop flatting the pipe or bend the pipe around the crossmember.

What's done to your Regal?

Very little so far. It's all in my build thread. (blue link in my signature)
Basically just paint, a carb+distributor, 3 inch sidepipe, shift kit, and sway bars. I have more in the works for it. I'm waiting for spring.

Thanks I'll check that out, looks very clean, hoping to have mine painted soon and one last question for you ahah, will these bumpers just mount on easily instead of the metal ones that come stock, my back ones rusted and I would rather get fiberglass ones before paint? If you know haha, sorry asked you a ton of questions already!

 

[307 Regal]

Unfortunately I don't know anything about the fiberglass bumpers yet. I did buy fiberglass rear bumper fillers but not the actual bumpers themselves.

Okay, I'm probably gonna just go with a single pipe with a dual outlet and new headers. But what kind of single pipe would I be looking for? Should I just go to an exhaust shop and see what they say, if they know, that is.
