Nice gains for a CBE! I wonder how much the 10 degrees difference in temperature effected the results. Probably very minimal. Congrats!

awesome results Dennis! was good seein you and the wife out today.

Altho Dennis :p tell the whole story man!

That's with factory cats?

Yes, its with stock cats.

the whole story?

gratz. thats some solid gains!

Yeah dude:p ur wifes ms3 and how she drives fasta than you :p

haha,,, lets face it with her car, she can pretty much beat all the stock 370z out there,, Her ms3 pulls like a mofo,,

I love a women who can handle fast car thou,,:driving:

Haha good call man!

Is this the one with the Y-pipe that goes into a single outlet and remains a single outlet until the tail pipes?

If so, that's very, very interesting!

Either way -- congrats!

EDIT: Just searched, and yeah that's it -- wow -- nice gains.

yeah its this exhaust

Whoo you just edited too!

haha

Meh, I thought the topspeed was supposed to be super cheap. It's only 100-200$ off from the invidia Geminii now. They keep raising the price on ebay.

The gemeni is 675 bucks? Cus i see the top speed for 465....

That's quite a bargain!:tup:

Rule of thumb is 10 degree reduction in intake temp gets 1% increase in HP.

With the Y Pipe? Really? Link???

Im just saying, I remember seeing the topspeed for around 500 total and it seems out of no where the price jumped up.

This is what happens when more and more people start buying it. they start to raise prices.

hrmm i'll ask about it.

I am planning on buying this set up with the Y pipe here in the next few days. I also have some Berk HFC's that I havn't installed yet. But I also have installed Stillen headers. Do you think I will have any fitment issues? Thanks

not sure,, but there is only one way to find out,,,,

Thats true...I ordered the Top Speed exhaust today, but I havn't had much luck in finding a magic y pipe....but I will let you guys know how it all works out may take a few weeks before I will be able to piece it all together....

Seems like a debate....but how much of a difference do you think there is between the JIC and the top speed Y pipe? I hate to settle, but if I can't find a JIC then I will purchase the TS....I don't like some of the bends on the TS, but do you really think it will matter that much?

alt370z...dont you have the TS Y pipe? and you made those gains with that one correct?

Anyone who has/or is ordering this exhaust care to weigh it?

From my email from the sender, Fedex has it weighting in at 57 lbs for both the CBE, and the Y pipe, I'm not sure how much of that will be packaging, but that atleast gives you an idea....

By picking it up both myself before, it was def. lighter then factory exhaust .

i kinda wish i didnt buy the stillen exhaust, i over payed for it, and it doesnt sound as nice as some systems out there.

Are these gains with the catback and Y pipe only ???? or the test pipes are also included on the dyno.

Factory cats, but I think I know what happened.

I bet the base line run didn't reflect giving the ECU enough time to adjust to the K&N filters (takes 3-5 runs for the ECU to adjust), which he claims to have also had installed in both runs.

So... my guess is that the baseline should be interpreted as "without K&N's" (even tho' they were installed) and the second run should be interpreted as "K&N filters + CBE" -- that is a more likely explantion for that big gain in power.

Still those are amazing gains for the price ! ! ! ! Im still undecided whether I should go with TS or Invidia exhaust. Everyone is very satisfied with Invidia and ERZ HFC combination and the sound is amazing too. But so is this TS exhaust. I hate this decisions......

Anyway this was a great review. Thanks

nice gains!

Can anyone tell if this exhaust, by been not true dual exhaust, will have any effect when combined with other mods? Im still worried about this exhaust for not been a true dual exhaust.

I'm in the same situation. I like the sound of the TS better, but it sounds it might drone on the freeway.

I just caught wind of this. From what I read,heard and saw about this TS exhaust=Winning! ha
I mean CB cost includes res Tps and piping being @ 2 3/4? Thats a pretty ill deal

Ok, I decided to give TS a chance and bought the cbe and y pipe from them. I'll post more when it comes in, should be here tomorrow! Xmas is coming early!

K&N drop-in filters actually do anything on this car? HUGE filter-area for them to actually matter. I don't think enough air is moved for the stock filters to be a restriction, but have been wrong before.

Well most of the articles I have read show that drop ins don't do that much as for a large increase in hp. I think the best you'll see is a little more response in your throttle but not much. Good luck though...also just go CAI!

I dug around on here. Found a verified repeated dyno of an Avg HP gain of around 5whp with k&n drop-in filters on the 370.

So like I said not a lot lol. CAI usually will net u 10 to 12 depending. Not to mention it sounds great on our cars.
