Great information from everyone on this poll and question regarding sidepipes and tru-duals.
There is almost 69% of respondents advising they like sidepipes more than tru-duals. I am really leaning to going with the OBX sidepipes and covers to avoid the burned legs.
However, I will need to be careful because there has been a new local law passed regarding noise and if that is going to limit the ability of the sidepipes to flow properly then I might have to stick with a good flowing tru-dual system with good performance mufflers. I will have to see what kind of decibels the OBX sidepipes will produce with baffles and hope it is below the noise level of the law.

My 69 468 has Hooker sidepipes with STS Baffles and Jet-Hot coating. Interior temperature is a non-issue. I recently put cheese-grater heat shields on the 4" tubes and after an hour of driving, you can put your hand on the heat shield and hold it there. It's not an ice-cube by any means, but you won't get burned.

The leds were a " lets see what it looks like" experiment. They are stuck on. Will do something diff. for running lights using the existing front amber lights. This 81 is by no means stock inside or out. the interior is custom and I will be gutting the dash and console in the fall for a full custom digital dash panel with large touch screen in the center stack. Pulling the factory A/C and installing a Vintage under dash unit.

I think another reason side pipes have been run on race cars historically is if you bring a car down to powerbook suspension heights, there is not a lot of ground clearance for large diameter pipes. A high HP/RPM big block with 2/18" to 2 1/4" primary tubes into 4" open side pipes wouldn't clear the even the smallest of bumps if routed underneath.
Speaking of race cars, I think this is one of the best looking race cars of all time, besides being tough on the competition in it's time. If I ever had the money and time to build a street replica race car, this would be it!

I've read discussions about the size of the primary pipes of most header/sidepipe setups being too large for most small blocks. Four 1 7/8" pipes look wicked but not optimal for performance.
That being said, I'd still like to have a set simply for appearances. The cool factor would make up for the minor difference in horsepower.

as much as I hate the look of most sidepipes on rubber bumper cars I'm planning on going with some '69 style pipes on my car this spring. Reason being the ground clearance issue. I have very little with my current setup and it scrapes on everything. with my modified crossmember and the lower drivers floor pan on '81s, it's pretty much my only option right now.

side pipes vs tru-duals
honestly I understand both point of views and agree performance gain or lost depends on many factors but for me personally I cant stand the looks of the duals running under the rear-end as viewed from the back, it looks like an after thought

chevymonza,
Here ya' go...did this back in 2011. Truly is the Best of Both Worlds. I'm really late in getting dyno runs of just the undercar system as well as both sidepipes AND undercar system open. I WILL be doing this this spring (if the bloody white stuff decides to melt
Realize my approach is to a low horse, flat tappet cam setup with stock ramshorn manifolds compared to what's here on this thread (500 + is the norm).
Anyhoo, enjoy!
