Ive been doing quite a bit of research on single exhausts and i think i would choose a singe over a true dual like the HKS for instance.

The main reasons being...
Half the cost of a dual exhaust set up
Quite a bit lighter
Supposedly provides 98% of the flow a dual exhaust would (depending on your set up), which brings me to the actual question i have for everyone...

The single 3" exhaust is very popular but would it benefit the Z to go bigger?
And what would be the cut off point for a NA vs a FI 350?
I have also learned that a oval shaped pipe is sometimes used to increase the overall flow without eliminating ground clearance.

On with the educated opinions and hateful threats....
Never know what reply you will get.

 

3" is nothing, my exhaust is 6.5" header back

 

Some serious answers / opinions is mainly why i registered to this forum.

 

search !!!!!!!! i swear everyday there this more people joining asking the same questions that were asked years ago. If in 2010 you think of something about a car thats been out since 2003, someone else has asked it.

 

I have a 5" straight pipe from the headers back. I lost a lot of power, because I didn't do research to find out how a larger diameter exhaust can actually hurt me more than help.

 

5"


lol


5.2" beta version from stripperspeed.com

 

I remember a shop installed 4'' on a 350Z with powerlap GT35R kit. (actually they used a Supra catback)

 

Don't come around here selling stupid because we are all stocked up!

 

That supra exhaust was used on a 07 nismo with a custom twin that Jermey did @ his old shop in Orlando. Correct me if I'm wrong...... very nice exhaust... HKS Carbon Ti I think?? Was a long time ago..

 

Lmfao

 

3" is common. Look at the MotorDyne single here: www.motordyneengineering.com An oval tip is not ideal.

 

nah.. I'm sure it was Power Lap GT35R kit

 

Ahh.. lol... u got me. It was the Nismo V3 bumber that got me. That build was a while ago.... deff good memory and one of the better singles I've seen with that bumber. I wish someone would mod that turbo to an hr... would be Nice =)
