1968 442 Exhaust question
If I am running the original manifolds on my '68 442, I want to get a 2 1/4" pipe system, correct? I don't want to get the wrong size system, not to mention I'd like to fit the original "trumpets" on the tail pipe (which I believe need to fit a 2" interior diameter).
Thanks. |

That is the correct size, but you can use bigger if you want. I have 2 1/2 inch exhaust pipes on my 72 VC, and crome tips on a 70 with 2 1/2 inch tail pipes, had to weld them on, but I think the company Pipes, not sure if that is the correct spelling, but that is were I bought the 2 1/2 down pipes, and I know they also make 3 inch tips.

OK, thanks. Well, I'd like to use the factory trumpet exhaust tips. Which, I'm not sure will fit properly with a 2 1/4" pipe either. If the inlet is 2", which is the original tip size, then is should really fit a 2" pipe, I suppose.
What have people done in this case? I definitely want to keep the original exhaust tips. |

Take the tips to a muffler shop and ask to see them fit.

My friend owns an exhaust shop. He has a hydralic tool that stretches the pipe to fit a new bigger diameter. All good shops should have this. I watched him fit an originally smaller pipe onto a larger pipe with no problems. I agree with you. I want the stock tips too. They look the best of anything I have ever seen. GM wasn't sleeping when they made those.

Pypes Exhaust sells 2.5" head pipes that bolt to stock Olds manifolds. They also sell trumpets that fit 2.5" tail pipes.
