Wow!
The sound is simply awesome!
Sound in this case will speak louder than words I’ll let the Stillen CBE / Berk HFC combo, do the taking!

That being said the Stillen / Berk combo produces a very unique and distinctive sound that for me sounds just right not too low or over the top, but just perfect IMO!
My Nissan mechanic Martin came away with a big grin saying” Ok you’re winning me over with this one , you know I’m the OEM type, but this sounds great thru most the rpm range and no notable hiss or drone", however he did say the demon bolts had to be heated, 2 hours from start to finish, he was also every impressed with the overall fit and quality of the Berk HFC, noting that it was just a bit larger in diameter than the Stillen “Y” pipe , finally he told me it would get a little deeper and louder in a few more driving cycles.
Last words to any on the fence about Stillen CBE / Berk HFC combo is hard to beat at any price, this is a proven winner in gains and sound, this exhaust may not be the newest or the hottest bolt on out there or have the prettiest welds, or ideal tips for some, and by far not the most exotic exhaust , but its designed by a race car pro to preform and sound IMO the way a true spots car should and that it does !!
Wow, thanks Stillen CBE, Berk HFC!
