Also the flanges on the entry have a little curve to them but I think they'll be fine once tightened down along with the gaskets. I'll post up some pics in a bit.

P.S. Not trying to take over your thread, spearfish. ERZ said they wanted to try and keep all the info in as few threads as possible

let me know how they do on the install, I ordered some too and they should get here soon. looking forward to some extra power as I lost a good bit coming to TX from GA in altitude and going from 93 oct to 91 oct.

I'm going to attempt the install this Friday night hopefully. I'll post before and after vids and dB readings.

When you do the install can you get a pic of the stock cats insides and the ERZ insides for a side by side comparison, to see how much less the restriction is? Reps if you can, thanks.

I just looked at my stock cats the other day. The difference is ENORMOUS! The stock cats are much more restrictive looking (densely packed).
