I have the Z-tube like everyone else. I was wondering that if I get a "coupe midpipe" and a Blitz Nur Spec muffler, will the whole exhaust sound ricey or nice? I know that there have been past discussions on the topic but none of them address my question directly. If anyone has a clip of the "sedan high- flow midpipe" a.k.a "coupe midpipe" installed w/ or w/o a muffler like the Blitz or HKS , can they post it here for all to hear. Gratzi.

 

no thats the exact setup I have sound really good. It is barley noticable at idle but opens up at WOT but deff no rice. Sounds really good and even passes the wife test. If i figure out how to record a sound clip I'll post it.

 

That's the setup I'm going to as well.
I have the HKS now & will be adding the midpipe in next month.

The HKS has a nice rich tone but mello, the midpipe should bring
the tone down deeper. I'll post my impressions when done.

 

Does this void warranty in any way? I mean, installing this.

 

I am pretty sure that only the parts that you change such as the "midpipe" and "muffler" will not have an Infiniti warranty, but rather the company or place that you buy the aftermarkets from will give you their warranty. Other than that, all the stock parts that came with your car are still under Infiniti warranty. Please anyone correct me if I am wrong about this.

 

Listen guys, I want you to tell me which setup will get me the sound closest to the coupe (i.e. midpipe with a certain muffler, etc.). I want to hear that coupe sound everytime I touch that "gas". Also, I don't think that the borla or stillen are even close to the coupe exhaust. Please, just tell me and I will do it.

 

I have the Fujitsubo exhaust & y-pipe. Sounds very good.

 

Thanks anyone else? Can anyone post a clip of their exhaust for all to hear?

from my mod unfriendly dealer in cali "infiniti doesn't really care what you do after the cats. anything before that i.e. cats, headers, intake, plenum, pulley, ecu reflash, blinker mod, your pushing your luck." basically, once you get past the maf sensors, you can't really do much damage.
hope this helps.
