I had a shop procure and install them so I'm not sure of the model number. They said it was the only HKS for the 370Z that's imported to the USA< so not sure if that helps. It also supposedly only comes with the blue titanium tips so with that and the extra Helmholtz canisters you can see in pics nears the end of the exhaust (see below) you should be able to get the right ones.

Sooooo back on topic(ish), what would be a good setup for this scenario: Deep Deep rumbling tiger purr while putzing around my neighborhood, with a banshee wail above 5200? Also my car is stock and this would be my first mod.

for something lower tone but still opens up would be either....

FI LTH w/ FI non-res CBE SS mufflers

if LTH's arent in the budget start with the CBE then add on later.

if volume in general isnt an issue wellllll..........

im sure up above 5500rpm there definitely be some wailing on this exhaust...

(NSFW)

i wonder if it's running.......

so hot.....lol

fixed...lol

Too bad litespeed dont make these anymore. And I heard there were some fitment issues. Did you have any issues with the litespeed exhaust?

No issues with fitment at all. Everyting lined up perfectly. It took about a month to get because I think they were made to order but it was well worth the wait. The customer service was A++. They also hooked me up w a great price on the intakes which was awesome also.
