which is the best Exhaust that will give more hp

[blackend_uae]

hi guy i want to buy exhaust for my car 350z and i want your advice for the exhaust.
is the 350Z Borla True Dual Performance Exhaust System is good?

If you have access to old copies of Sport Z Magazine, check out the exhaust comparison they did last summer. It was a great read. The Borla system is supposed to be very good, as is the new Injen system. I went with the Nismo, thanks to a very good deal I was offered. The Stillen exhaust made the most HP I believe. ?

Stillen - however it does not provide any weight savings. It also does not have as many pieces as the Borla. Great sound!

Don't quote me on this, but from what I've read I agree with the previous posts here - The Stillen & Borla show better gains, but the Stillen is one of the heaviest aftermarket exhausts & the Borla has many pieces that need to be installed correctly & fine-tuned to eliminate rattles. The Injen seems popular now as well. I'm happy with my Nismo (& Crawford headers & cats). Heck, they all advertise decent gains - ha! Who knows............I think it varies from Z to Z and the sound you want.

I love my Injen exhaust. Its very light, easy to install, sounds great, is affordable, and gives you a decent gain in power. :thumbsup:

im really happy with my borla.......great sound but controllable, i can tell a little difference in power but to me, on this particular car, if you do exhaust your doin it mainly for the sound

I chose the Stillen for two reasons:

1) It's a true dual system with X-Pipe design.

2) It's near the top as far as HP gains compared to other systems.

A nice side benefit is that it sounds and looks really good.

injen or evo2 for power. i love the nismo sound however.

This my opinion and no scientific research behind it, but the duals give around 11-12 HP increase while the single ones (similar to stock but bigger diameter) give around 7-8 but if you add a y-pipe which gives around 4-5 you will be at the same increase as the duals.

My thoughts are that the duals probably lose some low end torque compared to the single, but would be great for Turbo setups which love open exhausts, I am probably going to go the dual route now that I have TT, being that it is so quiet now I might venture with straight 3" pipe and no mufflers :) but that is another subject.

Love you're car! How do you like the blower? Any pros or cons? What size wheels do you have? They look really sharp!

I have the Tanabe, great design and light weight also

[redlinez33]

I have the Injen ses straight tip exaust and I have loved it ever since i installed it.

They all give about the same. Stillen seems to get the most, but doesn't look as nice as the other's.
