Offical Gruppe-S UEL Header Install & Review Thread

[blkdmnd]

Just installed mine after having invidia catless fp and N1, put stock fp and cbe on, then gruppe-s op and headers. Also getting the rattly/hissing noise near the connection of the header and op. almost louder than the exhaust itself sometimes

Chek for leaks, put soapy water in spray bottle and spray a little while engine running where leaks are suspected

No weird noises after 2 years

So that is what it would sound like? I tightened it as much as I could im pretty sure. I also used washers that came with it, maybe I'll take those out.

No hissing sound for you at all? did you use oem hardware or from them? what about gaskets?

Oem parts only. Maybe it's there, but I've never noticed it.
I've had it 2 years, added 2 different fp/op setups, 2 exhausts, and installed a turbo and no headers sound that I've noticed besides that sexy subie rumble.

I really wonder if it's the hardware they sent like the gaskets. Where'd you get your gaskets from? Also should I use oem nuts and bolts?

I think i'm experiencing the same thing from the same area. This whole time I was thinking it was my front pipe since its my last stock exhaust piece, but I guess i'll go check that area. I checked for a leak and I don't think that's it. that raspiness/rattle only happens at cold start and sometimes when accelerating.

Mine happens a decent amount when accelerating but I can’t always hear it with windows up. I’m almost 100% it isn’t a leak bc I felt around the area while it was being revved and no air. Def near the overpipe and header though.

Maybe not related then.

Update: I fixed it. It was just a leak because I didn't tighten the inside bolts well enough, and eventually one came off making it worse. Tightened with a crow's foot and extension socket bought at pepboys. Will be going to a friend of mines shop to make sure they're as tight as the others . IF ANYONE HAS THE FLUTTERING NOISE MAKE SURE THOSE BOLTS ARE TIGHT!

Installed mine a few weeks ago. Initially I flashed OFT stg 2+ tune which I used for 600km or so. Then I got a custom tune done by Tomm.brz,[Thanks again]. The car feels noticeably quicker from 2000-5000rpm, and pulls strong to redline.

Sorry if bumping this thread is a problem. I bought a new to me 2013 BRZ back in Dec. It had a way too loud TRD cat back which I have replaced with a stock system. According to the build/parts list from the ad, it has this header and a Berk catted front pipe. The gasket at the header to over pipe is blown out. What size do I need? Is a stock gasket to small? Or does it need to be bigger? I haven't been able to find much info so far.

Thanks
