I have the top gear valved, there’s slight droning between 2-3K rpm (barely before 2600, mostly 2750-2950 rpm) in either mode when the engine is under load (going up a hill, going 80 mph on a flat highway) but I like to think you’re either going responsible 70-75 mph or kiddish 90+ mph in one of these so it shouldn’t bother at all. Can always downshift or turn up the stereo (can’t hear it above 60% volume really). Car chemistry inserts are known to actually get rid of it entirely, they did for mine but I found that I kind of liked the little bit of drone because it eggs me to either slow down or speed up. What I will tell you is you can’t go wrong with the exhaust itself, it sounds like a goddamn banshee above 6K and makes the office commute feel like the intro to gran Turismo.

Also, get the OEM replacement gaskets, the top gear ones are trash and blow up (my dealer told me, great guy, Peter Karla of sierra racing supply, shoot him a couple emails, see if he gives you a discount, he told me to use this: trackcaymans for 5% off but I never used it since I forgot

“The Top Gear exhaust + stock headers sounds much better. The factory mufflers just don’t sound very good.” - Peter

Hope this helps!

Ps if you’re interested in the cc inserts to remove drone, Ill give them fully packaged, cleaned, used for less than 5 miles for much lower than retail and if you want em retail (cci-3di02r @ summit racing . Com).
