Opinion: Berk HFCs with stock Nismo exhaust

KingJoseph

Got the Berk HFCs installed and here's my honest take:

If you like the sound of the stock Nismo exhaust (which I do), this amplifies it a bit and it sounds great. I definitely feel like the car pulls harder at all engine speeds. I do notice a bit of rasp, but the stock cats sounded that way to some degree as well. In any event, I borrowed my buddy's heavily modded Evo X while my car was in his shop and, after hearing the turbo spool up in that and hopping back in the Z, I'd say the sound isn't all that far off. As such, it's not a horrible noise... just different. From what I've read on the forums, people say the rasp goes away with some break-in time anyway.

By the way, these cats are 10 lbs. lighter (total) than stock and the dyno charts shown here say they yielded 24 wheel hp for this particular car (***************************************/tabid/57/articleType/ArticleView/articleId/43/PageID/154/Berk-Technologies-Nissan-370Z-Downpipes.aspx). Not sure about the credibility of that site, but I definitely feel more power. Can't wait 'til my FI exhaust shows up to open things up even more... not to mention drop another 25 lbs!

Hope this helps anybody who's on the fence.
