Right, ew a real tough guy (sarcasm)....Im not an engineer.

Thank you RoadSpike for the breakdown.

if you run either over - they will both be flat....maybe you need some basic physics classes...

+1 s0lja, its doesnt matter. They do the same thing. So what if ones is 1lb and one is 2lbs. Are you going to notice 1lb diff. --- no. The LICP is a great mod. Doesnt matter what kind you get, you will be happy.

Happy Thankstaking.

 

get steel, aluminum + meth injection = no fun...

 

Thanks for all the suggestions everyone, looks like i'll be contacting cij911 for his pipe...btw, there arent any fitment issues with the nisei are there?

 

I like the steel ones with support bracket...this piece sees a lot of vibration and flexing so I think the bracket will minimize the movement but remember to use better clamps as well as some good old hairspray.

I have 2 concerns with aluminum but it depends on the gauge thickness, 1. if you make the clamp too tight you may damage the pipe and 2. the ones aluminum with support bracket may see cracking at the weld location of the bracket and pipe...but what do I know!

 

I have the AMS LICP. No issues with it vibrating. Works great, just wish it wasn't polished.

 

Mild steel (e.g. 1018 steel) is pretty soft stuff. About the same yield strength (or even less) as a hardened aluminum alloy. But wall thickness needs to be considered as well when determining strength. Anyhow, strength is a pretty meaningless parameter when considering a LICP. Its not a structural member, and either steel or aluminum would get smashed flat as a pancake if it managed to get completely blown off the car and run over (which seems very unlikely).

The cost difference between steel and aluminum is purely due to the price of aluminum. I prefer aluminum because its never going to corrode. I also prefer lighter weight of aluminum LICPs due. The Nisei aluminum LICP is about 1 lb whereas their steel one is about 5 lbs. Pretty small difference compared to the weight of the car, but I'll pass on the extra weight if there is no benefit associated with it.
