OK so since the search engine is down, I am trying to figure out which exhaust will give you the most bang for your buck and the most power. Of course sound should also be factored into it. I saw this article on the internet:

http://www.sportzmagazine.com/exhaust.html

Does anyone have the results of this or a link? Or does anyone have any feedback on what exhaust they prefer or not.

 

Borla made the most power.
I also think Borla sounds the best... not too loud, but definately recognizable.

What do you think?

 

DON'T TRUST SOUND CLIPS!
Boral produced the most HP and is one of the cheaper. Lots of pieces and lots of arguments both for and against.

 

I did a little reading before I bought. The Borla was my choice.

Pros: Most power, true dual design w/ crossover pipe, deepest sound, dual tips like stock (but better made), heavy duty stainless construction, lighter than stock exhaust, lifetime warranty, not too loud

Cons: More pieces than most other kits, can take longer to install, some people fear more pieces = more leaks, not loud enough for some tastes.

I think a few of the earlier Borla kits had leak problems and that did a lot to cement the "borla leaks" idea. XX Tuning has installed the Borla several times and they say they like the kit and and no problems with aligning the parts or leaks.

My Borla has been on for about 4K miles now and I love it.

Alot of it depends on want you want. If you want a raspy exotic sound, this may not be the exhaust for you. If you want a deep rumbling sound maybe it is. If you want to keep the dual tips and back em up with a real dual system, the borla is good. If you want a single large exhaust on one side look elsewhere.

That's my $0.02.

 

They may have produced the most power up to the point the test was conducted. But there is always room for improvement. That is partly the reason we waited longer than most to introduce an exhaust system. We just need to get a couple out there and I'm confident the consensus will change.

 

What is the HP increase with the Borla Exhaust?

 

I'm italian , live in Florence , and is the first time in this very interesting forum ; all the best to everybody.
My questions :
Does Borla True Dual Cat Back System fit to my new 350Z , european setup ?
I'm deciding on Borla after having read your interesting posts about exhausts systems.....

 

Ciao Guido,

finalmente un altro Italiano in 350Z..., io sono un ex possessore di S 2000 adesso devo prendere un 350Z, dopo essere passato da una Evo VII.
Il dual sistem è il migliore sistema di scarico(più HP) per la 350Z, stillen e borla sono i migliori, sul dual lavora anche la 5zigen e la HKS, sempre su diametri di 2,5 inch (63,5mm).
ti lascio la mia mail poliatt@yahoo.it

 

another test showed borla as the least.

 

So danf ....how much for that exact set-up ....it sounds sick!!!

 

We will be moved into our new shop by the end of the month. The lift is being moved on the 27th. Once we are set-up we will be pulling the system off of the test car. I'm hoping to have all systems and prices complete by the 3rd week in May.

Stay tuned for a forum speacial. Thanks.

 

i have read that stillen is overall better than the borla....i read the borla actually loses power in the lower band....
