Top Speed Exhaust Review
 

Well its one more thread but this one is mostly just to review it on the first page for anyone else who would like to take a look at the exhaust. First off, I have the y-pipe with it which you can get as well and I would definitely recommend you getting both the y-pipe and the top speed exhaust together. (Still cheaper than every other exhaust option)

First off, I picked mine up from this guy off ebay. 370z items - Get great deals on Exhausts Headers Manifolds DP items on eBay Stores! Seems like a really good guy. Had good communication when I needed to make sure it shipped at a certain date to arrive at a certain date.

Review!
I personally love the exhaust tone. Sounded great, not loud, no resonance in the cabin.
Its extremely cost effective compared to the other exhausts out there and while I love the tone, some may not, thats personal opinion.
By judgement from the butt dyno it did make a difference in the power. Also by a proper dyno! (talked about later)

Here are two videos and some pictures.

Okay so some people have said its trash, that the single pipe won't make power etc etc yaddy yadda. Ive seen other single exhaust setups do well with power and no one questions them. I guess when the price tag is up in the thousands people automatically stop thinking with their brain (or when its less than 500) Essentially it does make power.

Red line = Top Speed Exhaust. Blue Line = Stillen Gen III

So there you have a direct comparison between the Top Speed Exhaust vs a Stillen Gen III intake system. Dyno's were taken on the same day in the same awfully hot weather conditions.

As has been discussed in a different thread, the baseline for each car were the same as well when they were done on the same day also.

So its cheap, it makes power, it sounds good (to me). The verdict? Its definitely worth it... for most.

There are some people who are not happy with the exhaust until they spend alot of money on it. Money = quality to these people and while I don't agree, I don't have to agree. I like the tone, some may want something louder, more agressive etc. Some wont be happy till the tips are bigger, blue, stick out more etc for looks.

Just take it for what it is. You like it or you don't but by a purely statistical value, its easily worth it. and from my personal POV, I think its really good.

I'm confused as to what the dyno is comparing? Is the blue line the Gen 3 with the exhaust and the red line with just the Gen 3 intakes? Otherwise I'm not sure the point? Comparing an exhaust to an intake doesn't make much sense to me unless you were comparing from a purely cost per HP stance.

More of a fact that the exhaust creates power. Same as the gen 3 does which has been shown time and time again to do so. Simply stated take one dyno and people can say variables this or that. Take 2 dynos on same day one with new mod one with a proven mod and its a much much much better comparison.

Blue line is gen 3 only
Red line is top speed exhuast with y pipe only

Wouldn't it have been better to do completely stock vs exhaust? Or car with Gen 3 vs car with gen 3 and exhaust? Intakes for the most part provide gains only in the very high RPM range where as exhausts usually give gains somewhat throughout the RPM Range and a little bit more at high RPM. This comparison is just weird. It would have been nice to just see exactly what gains the exhaust had by itself. Exhaust does sound pretty good though and since it does make some power, I guess its worth it.

awesome review!

nice! I'm getting this exhaust! It's one of the best sounding ones I've heard.

I bought this exhaust in July. I love it and have nothing but positive feedback about the sound. If you are on a budget, well worth it. Another happy top speed customer here

It is a awsome exhaust! sound=good, price=good:happydance::happydance:
Thank you daisuke once again!

Kind of sucks how the power just flatlines after 6500rpms no?

On the exhaust only run, I am guessing you were using a stock airbox? Maybe that restricted the intake flow a bit?

yup stock air box.

Is my math correct - Y pipe plus the exhaust is close to $800 total?

The sound is definitely an upgrade from stock.

the guy i got it from has em both for under 700 shipped for those. and has the test pipes for like 780 shipped.

the Lotus guys love their exhausts.

as already stated in one of my video posts I also have this exhaust installed from day one and now drove it for around 5500miles in the city, on the autobahn and also on several tracks in Germany.

Not only that it definitely makes power (compared to other 370Z with stock exhaust system I raced against) but it also is excellent quality which survived everything from rainy weather, high speed drive (155mph for several minutes on the Autobahn) up to 20minute runs on a Grandprix race circuit with extremely high revs and high gear changes.

There is nothing else to say than its absolutely flawless and worth the money big time !

Chris

you know, it's funny how stuck up the 370z guys seem to be about stuff like this. They frown on it because it's not a big name exhaust... where as the Lotus people, which I assume are in a higher tax bracket and can afford a more expensive exhausts, look at the actual quality of the exhaust, and not the name or price.

Disclaimer: I'm poor as ****, so I'm not talking about myself being rich or anything.
However if I do get the Elise, I'll be getting the TS exhaust lol

I didn't see one negative post about this exhaust. There are quite a few "small name" exhausts featured on this forum that get very favorable reviews. So I don't see where the hostility you mention is coming from. And as long as that single center pipe has enough diameter, I see no reason why it wouldn't be a decent mod with good gains.

Seconding this.

Most "big name" high priced exhausts get panned to hell here. The only ones that are universally loved are the ones that produce big power.

http://www.the370z.com/intake-exhaus...d-exhaust.html

ignorant comments like the above.

Here's the same poster, after hearing the exhaust:

I think his point was that the metal used in a cheap exhaust is not going to be up to the standards of the more expensive ones. And there still is a question about the diameter of that middle pipe.

Too bad the comparison was not between this exhaust and, say, a Stillen, FI, or Berk, rather than with an intake, which is pretty weird for a comparo.

I agree. The 370Z crowd is very brand conscious and loyal. I bought Boombop Shop CBE which IMO is a great exhaust and people complete ignored it. I heard Daisuke149's TS set up in person and experienced it as a passenger and I give it 3 :tup::tup::tup:

Great review Dai

well the comparison to an intake was purely due to the fact that people in other threads have been stating that this exhaust would make no power being the single etc. now, someone wanna send me another exahust system i'll be glad to compare the two :-D

thanks, i think this is what i may get.

Nissan 370Z Z34 G37 VQ37 08-10 Exhaust Test Pipe Pipes - eBay (item 230526393014 end time Dec-13-10 17:49:37 PST)

how about the test pipe?

is it worth to purchase?

If you want testmpipes its worth it. I unfortunately like a quietmtame exhaust and so test pipes isnt good for me

Power. Quality. Sound. Those are the three most important things I look at when I'm buying an CBE. If an exhaust sounds great but produces terrible gains then I wont buy it. If it sounds terrible but gets high gains then I wont buy it. Quality is definitely important all around.

If this exhaust produces the same type of high power [or near] some of the other big name exhausts are I'd buy it in a heartbeat. I still find it odd that the comparison is with an intake. We expect exhausts to produce power and we expect them to produce more power than an intake.

Any chance we can get a graph WITH the baseline?

http://www.the370z.com/engine-drivet...no-result.html

closest one I have for a vs baseline.

Not bad. :) Thanks man.

+1 to you Dai for taking the time to do an independent test and study of this product...This is the very reason for this forum, so that those of us out there can share our knowledge and experience with others....Some will like it and some will not, but if reviews such as these are not done, then everyone will be on the fence and come up with nothing but pure speculation.

Like I always say...Don't knock it cuz you can't rock it!!!!

Cool man. gave u thumbs up on youtube. and a nice comment. Thanks.

What ever happened to the Ark dai?

I have it man. Showed it to a buncha people at yesterdays event. This top Speed exhaust/review was a long long while ago.

Ahh my bad. I really wanted to come out but things just didn't work out.

that sucks man. it was a big good time.

nice

I have stillen gen 3s, berk HFCs, JIC ypipe, topspeed exhaust and I love love love everything about this exhaust. I came from stillen fatback so I will be able to shower power comparison from jic ypipe + topspeed exhaust vs. Stillen Cbe once I get back on the dyno.

Catback*.... typing on phone lol

:icon18: I thought "fatback" was a poke at the weight gain that comes with the Stillen CBE :icon17:

I was wondering if this exhaust (for not been a true dual exhaust) will affect the gains when integrated with other mods ??? Please let us know if you feel any change in performance at all.

:roflpuke2:

me too! I remember asking him how much it weighed when it was for sale and he said allot!

Yes, please keep us update on the comparison!
