I am trying to install D&Rs 2-1/4 exhaust system (non-chambered) and have a question because this kit had no instructions and I have never done this before.

How tight do the extensions fit inside the pipes? Mine seem like I would have to press them in for them to fit inside the pipes.

I am talking about these small extension tubes that support the donut into the exhaust manifold seen here: http://www.heartbeatcitycamaro.com/store/product/21193/Camaro-Exhaust-manifold-tube-SB-1967-1968-1969-1970-1971-1972/

If the parts are made properly, the extensions should drop right in without having to force them.

Ok thanks. It looks like the extensions I have may be too big for the pipes then. Back to the parts store...

Might try putting them in the freezer for a bit before you return them. Might or might not shrink them enough to go in easy. Good luck either way.

  It may be tight possibly from being slightly out-of round. If it looks like it is just a tight friction fit and not an obvious over sized OD, then try putting a thin layer of grease on the flange and using a wooden block across the OD, tap it in.

Again, this is only if it looks like it wants to go in but is just snug. I use grease at times for stubborn exhaust fittings and it works great.


Good luck!

What source are you using? The ones at Heartbeat don't list O.D. My D&R 2 1/4" aluminized system didn't come with them, so I have none installed.
Does NAPA source them? I'd like to buy a set and put them in.

I'd think any good exhaust shop could make those for you...  if they have access to the pipes and exhaust manifolds, or exact measures.

Thanks for all the help fellas! I ended up going to a local auto parts store and finding what I needed there. They need to be trimmed down a little (too long) but other than that they slipped right in.  Two pieces for $5!
