F.I. Catback exhaust Cold & Hot Start procedures?
 

Sorry if this is a repost as I think it is, but I cannot find this anywhere. :(

I got the F.I. Catback exhaust and I read somewhere about the cold & hot starts procedures after the exhaust is installed.

Can anyone with a F.I. explain it to me or point me in the right direction?

Because I'm installing mine tomorrow.

Thanks!

You just want to run it through a few brief drive cycles to break it in. Drive around town for 15 mins or so, come home, leave it a while... take it back out and repeat. Only need to do it a couple times.

Interesting, and why is this?

It's to put the exhaust through a few heat cycles for a proper break in instead of taking it out for one extended drive since the metals will expand with heat and contract as they cool.

I have seen this before too. Read through the FI thread in the Intake/exhaust section. I know it is a long thread but I think there were a number of discussions about it. If I remember right, heat cycling will help to seat the packing in the exhaust for longer reliability.

Thanks Steve!! Didn't recognize your new avatar.

I didn't know this - cool & thanks!

Is this for all exahusts?

No problem. Yes, my new avi is a big change! :icon18:

Yes. :hello:

thanks! about to place an order for my exhaust, good thing to know. :rolleyes:

To tell you the true, this is the first time I have heard this and I had over 20 cars modified.

My thought was because the F.I. is a custom exhaust, not a mass produce one and that was the reason...but it makes sense!
