want to back any of those claims up with any dynos?

 

i don't have to son, ask anyone who had one.Well any how i'll find the dyno sheets n post them here.Hks does well with non stock cats with stock cats it sucks

 

Couldn't post pic's.. but here i had dyno 270 with intake and pulleys, the 276 came when i got HKS i should of provided dynos for the pulleys and intake to make this more accurate and legit sorry but couldn't fin that one =(

back in 2008

 

Only dyno I care about is my butt dyno and my buddy has catback MD shockwave that cost him $1600 and my stock exhaust G35 ran side by side up to triple digit speeds.

 

^^so 6hp overall gain with intakes which even "the best" non-oem types are known to likely lose 1-2 whp along with pulleys that are generally regarded to not cause any change in whp. That is 6-8whp gain from the HKS exhaust in that case.

Now sure that is a few whp less than MD but the price is a bit cheaper as well. Now compare that to the x02 which is ~$1k+ less and then think about the statement "bang for your buck."

I'm not saying md doesn't make great products, and in many cases the best in terms of power, but you yourself have proven the other exhaust options aren't nearly as terrible as you stated before.

Yeah big money

 

You realize there are probably other factors that contributed to the outcome, right?

 

Please elaborate, all im saying is that you spend a lot of money on an exhaust system and there are very minimum gains besides sound IMO

 

as far as the OP, have to say XO2 (knock off hks). Allot of the 350z guys running it said they felt a difference in the upper rpm range (butt dyno of course), but it costs like 400$ and looks almost identical to the hks, besides the awful tips it comes with.

 

Best bang for the buck exhaust? HKS replicas. Cheap, and makes decent power. There's no arguing that.

This is coming from a guy with everything MotorDyne. Now if youre willing to spend the coin to get the extra quality and power, then go with the Shockwave. Keep in mind it's not all about 'peak' HP that an exhaust makes, but also how it alters the power curve.
