I can tell you that the Borla with stock cats and Strup headers sounds great. It doesn't sound like an "asian" car at all. Just a smooth, deep note. No rasp what so ever and only slight drone around 2000 rpms.

I may install a set of high flow cats in the near future because the Borla is quiet with stock cats. It is only slightly louder than stock except at high rpms and WOT. It is much louder than stock above 6000 rpms. Normal city and highway driving, it is barely louder than stock.

The biggest complaint with the Borla is the install and possiblity of leaks. Installation is a pain because there is so many different pipes and you need to tweak it for it to fit perfectly. As long as you torque the clamps properly and retorque them after a few hundred miles a leak shouldn't occur. I haven't had any leaks but if one does it usually happens in the H-pipe. That can be easily fixed by having a muffler shop weld it for $20.00.

thanks nismo...

 

look this is all you need either, RSR, Top speed Pro N1 then your Z will sound like an F1 car and not azn lol

 

I have the greddy evo2 and absolutely love it, but I also have headers and intake so I've never heard it with just an exhaust.

 

x2 - I hated the sound of a certain car on a certain car rally I went on (she had the HKS iirc). very raspy / worse than the e46 M3 with us

 

3.9 = less top end more accel ... they are shorter gears



+1 on RS*R topspeed ect ... I knew that was the exhaust I would get as soon as I heard the RS*R 350Z at a club 4AG drift day YEARS ago

 

Give me your HKS, Ill give you my stock one

 

thanks drift.

 

Exactly. If you ever want to "virtually" play with final drive gears, play a realistic racing game such as Forza (xbox), and you can manually select your final drive gear. It will show you how the acceleration and top speed changes for increasing or decreasing the final drive ratio.

For example, in Forza when your car is slow (N/A) you will want to choose much shorter final drive gears and an upgraded lightweight flywheel/clutch so you can shift faster (because you will be doing more shifting), but don't make the FD so short that you can't keep up on the straightaways.

When you turbo your car in Forza, you will want nice tall final drive gear so you don't have to shift so much, and since you will have much more power, you will have amazing top speed on the straightaways.

 

Sorry for being OT but when is Forza coming out for xbox360? LOL

 

i'll take ur hks exhaust

 

you need to go to a meet and check out the systems for yourself. Exhausts are very very subjective on these cars. To some, a Injen sounds "great"; to others, its far too loud

I also have no idea what an "asian" or "japanese" sounding exhaust is honestly, at least on this car. There are several Japanese brands that are not buzzy, droning, or offensively loud at all.

Define your budget first, and work from there.

 

+1, i'd rather see Import Tuner Challenge instead.(Tokyo Extreme Racer, renamed, Best old school game from Dreamcast )

 

Bump for Injen. Im not a fan of HKS personally. The first time I heard it on a G I liked it, but after hearing it on more cars, both G's and Z's, Ive decided I dont like it at all. Its too ricey and high-pitched for me.

I went with Injen due to the fact that its a lower note, sounds exotic, looks just as good, loud but not too loud, and its much cheaper too.

Here are some sound clips of my car driving by and sitting in the drive-way

see what I mean ^ it's all personal perception. One man's "not too loud" is another man's "completely obnoxious"
