Are new gaskets required with new headers?

[FR-S Matt]

Grimmspeed gaskets are what I use on my JDL UEL. Very high quality stuff. I highly suggest their gaskets as they are very fair priced too. Snagged mine at FT86 Speedfactory as well. They seem to drain my bank account a lot....

Yesi plan on it. Still stock gaskets considering I went to RW header to HKS header. When my stock manifold bolts on right side came off completly, that gasket was pretty black . Will take the advice and order

I reuse them all the time, they're pretty durable, but only when I'm putting the same manifolds(headers) back on. Replace gaskets and clean cylinder heads surface when replacing with new part.

I have reused mine and have no issues so far, How can you tell if there is a leak or not?

With a high quality gasket like ours, I wouldn't worry too much about reusing a gasket as long as you're bolting the same two flanges back together. If you're swapping parts/headers/catback/whatever, the flanges may meet just a bit differently and if your fire ring has already been deformed from a previous setup, you'll be risking an exhaust leak. For me, it's not worth the $20 to have to get back under the car and replace the gaskets later on, but if you don't mind the labor, it's your call!

First of all, awesome username.

I just did a quick google image search, so it's not the best, but what you see below is indicative of the deposits that you'd probably see if you have an exhaust gasket leaking. See the black?

Exactly why we have the package. It's a no brainier and should be done.

I'm about to order some GS from FT86 on payday.... Better to be safe then sorry. Personally Getting under my car is a pain in the ass. So id rather not have to get back under it. Ya feel me? $20 bucks could be spent in many ways.... But id rather be in my bed sleeping for a extra hour or two then under my car at midnight fixing it before work the next day..... Don't even want to post the pics of my reused header gaskets. My gasket that connects the over pipe to the header was crumbling to pieces.
