Installed the Flat 6 OAPs a couple weeks ago. Really great quality and I appreciate the stock appearance with the heat shielding. We also ended up installing the SOUL valve controller, and the sound level is right where I want it.

For me, these seemed to be the best combo of cost and quality of all the OAPs on the market.

 

Pretty sure that was the "good old days" price. Over two grand a set now.

Oh crap. Didn't realize I was quoting such an ancient post.

 

I had gotten the soul OAP used from a buddy of mine but didn't like the fact they had no heat shield. With the help of a buddy who has a guy who does oem type heat shield managed to do mine. Love the finish can't wait to install them

I came across this new to the market OAP from TopGear UK on FB, can't speak to their quality or sound but pricing looks good.....

I have no affiliation with either TopGear or Sierra Racing..... somebody buy this and try it out as I am still waiting for my warranty period to end (my dealer is a**l on any mod)

I wonder why they bellow them out that way, they don’t appear to be resonated.

 

I went with the heat shielded Flat 6 OAP's a couple of weeks ago, and couldn't be happier with the increase in volume and the sound at high rpm's.

I have a set of silenced Soul ceramic coated OAPs with about 3000 miles on them from my ‘22’ GT4 . Still look close to new. I’ll put them in the classifieds in the next couple of days.
