any body have an idea on size of pipe for a 3fe? would 3" be to big?
This is a good link that will provide some discussion and reasoning that could help you with your question.
The key is to keep your exhaust hot as it leaves your pipe with as little restriction as possible. If you 3fe is really cranking 3" may work. Otherwise, it may hurt performance as your exhaust begins to cool too much before it exits.

Good post. I may have an idea to make that piece work if I reroute my exhaust between the muffler and the cat. Ihaven't delved in that deeply to know if it would be neccesary.
jamisobe -- so are you in San Antonio, if so we should meet up some time since the LSLC chapter down there is no more.
Anway, with that new cat you put in, did you have any issues with the rear O2 sensor throwing codes?? I want to do somthing similar so I can get the pipe routed over the frame like the '93/'94s.

No code throwin'.
We used new sensor nuts from Jegs in locations similar to stock. Everything worked fine. I will say that I had to replace one of my 02 sensors previously.I'll pm you regarding meetin' up sometime. How often are you in the San Antonio area?
thanks for the replies i will have to keep the cats with our emmisions testing but the old exhaust is rusting out
Cruiserland,
I have been satisfied with my Bosal muffler replacement

I had a good experience with APW and you can't beat the price with a stick
ive used apw they are very quick with shipping, how hard was the bosal bolt up?
what tyoe of muffler did you use if any?
Does anyone have the BORLA exhaust? What size is the pipe over the frame rail?
I thought I would add this since it seems to fit. Here are two additional options for quieting high flow exhausts. Dynatech and car chemistry.
ADD Aero Turbo Exhaust - I'm truly impressed - you can hear sound bytes on thier website. Power improvement seems noticable to me - but the turbo spooling is a wicked sound.

I will take some measurements of mine tonight. IIRC there is very little reduction over the frame.
General exhaust comments
My exhaust guy uses a 4in mandrel to bend 3in pipe. It ovals the 3in pipe at a fraction of those prices.
Walker dynomax rounds are about the size of the stocker, and flow as good as the borla at a better price point. Resonators are key to keeping the noise levels reasonable at cruising rpms.
Romer, for a resonator, the oval 3in XR1 Borla is one of the best, low clearance available in a 12in length as well. It cuts the drone much better than a glasspack will, and has really good flow characteristics at higher rpm.

O.K. checked the Borla and there is no reduction in size over the frame.
In fact (at least on mine) it looks like there is about 4 inches between the frame and the heat shield. You could go considerably larger than the Borla (depending on your comfort level with clearance).
