flexible intercooler piping?

ok i was thinking since most people here use exhaust piping for their intercooler pipes...why not use "flexible" exhaust piping?! It would make the install so much easier not having to cut pipes. I saw this on the JC Whitney website and it's not too expensive either. It sounds like a good product...this is what it says

"Ideal for custom exhaust systems, side pipes or dual set-ups."

"Extra-strong interlocked construction won't kink or unwind. T304 steel won't rust even in salt water usage!"

What do you guys think?

Its probably not as smooth as the inside of real pipes with mandrels. Also there is probably a limit to how much bend you can get out of it. I wonder if it will make a tight 90. Buy some and let me know

I don't think it would flow well with all the grooves and stuff like that. You can sure try it though.

I'm sure it would be a great temporary setup until mandrel pipes are made. I know someone selling the HS fmic kit thats plug and play though...

cant bend that stuff enough, it would be very hard to make a tight, 90*

also, it would flow like shit.

I actually used the flex piping for my setup to take to the exhaust shop to make the bends for me. It holds it shape rather well. I just picked my flex pipe up from a local farm supply store, they have everything. It's called Fleet Farm, you may have heard of it depending on where you live.

I thought it didn't hold pressure though? Someone correct me if I'm wrong but maybe just the stuff I have doesn't and maybe the stuff from JCWhitney does hold pressure. I'm using a small section right now for my intake piping from my MAF to turbo inlet. If that leaks a little bit that should be fine because it just means I'll be running a little leaner but I'm already running rich so that would help my problem...hopefully. Really should install my EGT gauge to make sure of that.

flex pipe

I think you are all talking about 2 different products. I was at the SEMA show in Vega last november and thier was a company selling flexable intercooler piping. They had a flow machine thier and the flex piping flowed better than the exhaust piping normaly used for intercooler piping. They claimed this was because of the spirel the inside of the pipe made.It held up to 30psi.It could make a u shpe in 8" if i remember . Thats not bad ! I will see if they sent me any info on it and i will try to post back to let ya know.It even had different color choices WOOOHOOO!! HEE HEEE.

Are you referring to this?http://www.racingsportsakimoto.com/prod_spiralflex.php

Sweet, now we just have to find out if that stuff comes in maybe 2" and if it can hold boost pressure or not.

JMAC...let us know when you find out about the flesible piping you saw at SEMA

I saw the website for RS Akimoto...that thing looks a little flimsy to me and I don't know if it will hold pressure...but it would be great for CAI's

I don't mind being the guinea pig guys...should I try it? I won't be able to measure how much it flows *** compared to mandrel bends but I will try anyway...take one for the team!!

I found some industrial flex piping that holds pressure and is leakproof. Comes as small as 2" and at 2" diameter it can make a 90' bend in 3"! Those of us that want to keep A/C could use stock J-pipe and just go straight down from there to a FMIC. I requested a quote for a 10' section and will post prices when I get them.
Here is the link to the product:

The section that I have now is fine. No leaking so far and I have been turbo for 2 months now. I am going to have it replaced with a mandrel bent section when I have the intercooler piping redone.

TOMCAT...I looked at the website you posted here, looks like a good product, ask the salesman if it will hold boost since the air in the intercooler pipes are pressurized. If it does, try it...and let us know how much too...thanks!

I also got the flexible iping from JC Whitney but I havent put the turbo on yet, I just replaced my motor with a JDM highport so I haven't had time to do the turbo. The flexible pipes are not flimsy at all and they hold their shape very well. Tomorrow I will do some experiments with it (*mad scientist laugh...hahaha*)...I will post as soon as I get it in the car and find out if it can hold boost! Good luck!

ok guys i finished the turbo...the flexible exhaust pipes work! I'm only boosting 5 psi now, don't know if it will hold more boost but i think it will...we'll see when i turn up the boost!! just another option people can go with for pipes...
