hey jay. the number below is my cell phone. if you need some pointers give me a call anytime.

I really dig the way this exhaust sounds on the website, but I'm afraid it may sound too much like a mustang . I NEED HONEST NONBIASED OPINIONS Should I get this exhaust (and if yes, then 2.5 or 3") or the HKS hi power??? I will be ordering my exhaust THIS WEEK

 

wait until plumpzz uploads the video we took

its not great, but you can hear it well

his car does not sound like a mustang...just a great 350Z haha

what other exhausts do you like the sound of? this maintains the note of the engine well but is a lot louder.

sounds is all subjective, but what other systems do you like? ive heard the hks in person and i like this one A LOT better. the HKS sounds pretty damn good, but I don't think it's mean enough or loud enough.

 

I think the welding thing is a non issue. Nobody sells an exhaust system that is one piece welded from manifold to bumper. They are either flanges and gaskets, old style ubolts, etc. I will install mine with the clamps, if it proves to be a problem, which I don't believe so, I will have the joints welded. I dont have experience with the Borla TD, and dont want any, but correct me if I am wrong, there are something like 16 clamp joints on that system. This system replaces everything from the exhaust manifold back (cats, ypipe, mid pipe resonators, muffler. There are a total of 8 clamps, 4 joints per side. This is not excessvie IMO. How many joints do the other systems have, and do they use flanges or slip fit pipes? My experience with flanges on the 350Z and leaking make me want slip fit or welded. Go price the stock gaskets for the cats on the Z, they are the only gaskets that work right (read leaking) and they are not free. A slip joint has much less chance of leaking.

Perhaps Injen Ti and HKS Ti owners can chime in: How many joints on your system, how are the joints connected? That might help some people make comparisions. And this system doesn't HAVE test pipes, one joint eliminated. Anyone with a NISMO system - look at your flex sections. Are they perfect? Mine are chewed up bad - and I drive very carefully over bumps, etc. Those flex sections on the NISMO y pipe hang lower than anything else on my car - and it shows.

 

I had the nismo be4 my Borla and I sold it to another memeber who the flex section broke for. My borla has had issues with leaking and rattling, it took alot of gasket sealer and adjustment. I am not saying I want a solid piece from start to finish, I just prefer flange set ups like the nismo. I do not hear about them leaking.

 

I have the NISMO, and even with stock gaskets and cats, when I went over a bump at speed you could hear the exhaust gas escape when the joint flexed (windows down of course) Look at the gaskets on the NISMO between the cat and y pipe after they have been on some time, I did, and you could see in the laminations where gases had escaped at one time or another. Just my opinion, but I would rather have slip joints and clamps than flanges, esp. on a joint that has some movement pressure.

 

Not the case with mine, but this could be due to the bracketless HFC's I have, but I thought this was the problem with other bracketless brands so I don't know. I was just under there last night chasing a hfc/heat shield rattle and was a little surprised that the flex was pretty well flush with everything else based on what I'd heard.

Regardless, due to the HFC's, I want to replace the Nismo with something else due to the 3k rpm resonance/amplification. Over all the tone is still good to me, but not the inconsistant volume in that region under light load. This SVR exhaust looks like it would be a great replacement, except I wouldn't want the tp's. Any chance of a cat-back variant coming?

 

I am suprised to hear that about the NISMO, I was just looking at the side of my car, underneath, and I can see the flex sections - but nothing else. Perhaps there are two versions of the NISMO catback or revisions? Mine is a very early one, I have had it on for a couple of years, and the guy I got it from had it on for a quite a while also. I dont mean to knock the NISMO, it is a great exhaust, I was and am happy with it, just think my TTs need a TD.

 

Yeah, I doubt they changed the version, too many other people say the same thing about the flexes. I think for whatever reason, the setup I have under there just worked out to have very good fitment. It may have been different with the stock cats, but I didn't look too closely then. And yeah, I know you weren't knocking it, it's hard for me to part with my own.

 

I was not running brackets from my TP's so that mite have added stress to my flex sections

 

thanks scott...will do

 

^^

 

at the moment, it is not priority. we will be building an intake manifold next. wait to see this thing!!!!!!
i am very happy with the way we redesigned the front section (the look and especially the flow) that it may be awhile before we offer something cat back. it would mean almost a total system redesign.
but we may start offering a turbonetics variation that will go from the X pipe back, yet only have the rear 1/2 of the X-pipe creating a Y merge. then easy for someone to fab just the connecting pipe.

 

OK, thanks. Had to ask.

 

Intake manifold....and the hits just keep on coming.

I have held off on an IM because:
Crawford needs diff strutbar.

Kinetix is plastic (V+) or overpriced (SSV) (IMHO)

Spacers add double the seams and that is double the chance of leaks, the larger (better performing ones) have strutbar / hood issues

Others have been vaporwear (haven't come out) so far or non-performers (350evo, CJ, that coffin thingie).

Good to see someone else giving it a try.

 

i have the design planned out, almost all the manufacturing quirks worked out too. just need to start on the prototype. think top secret!!
itb type set up with adjutable length runners. polished inside and a clear top to show it all off. it may need custom fuel rails and a custom strut bar, the measurements are so close right now it will take building one to figure it out, but shooting for a bolt on for even a stock Z. we are also going straight off the head, not the lower intake, so again a total redesign. price will not be cheap, but comparable to others. this will have alot more bling factor and there really is no way to design it better, so tq and hp gains will be maximized. with adjustable length runners, people can tune the manifold to do what they want it to do.
i hate blowing my own secrets!
i might be new to making parts for the public but i have been doing this stuff almost 20 years now, and i'm only 33, lol.

 

I appreciated the feedback, I'll hold out til the video posts. I really love the sound of the rs-r but it's only a y-pipe back and not true dual. I was dead damn set on the HKS until I read this post last night. That thing sounds like a beast!! I just wanna be sure it's the sound i want.

 

That clip on the turbo car was BEASTLY I can only imagine how it will sound on a NA. I was actually driving next to a mustang the other day with some loud mean sounding exhaust and I thought to myself "I wish the Z could sound that aggressive." I think this exhaust could actually do that for you.

It is like a mix of the v8 and the exotic sound.

 

cough some of my ideas, cough. lol!

 

funny you mention that, because before you said anything, i was going to add that this exhaust kind of sounds like a cross between the HKS and an N1 system (RSR, etc)...just with more ***** than both of them put together. it has the exotic sound of the hks and the VQ amplification of the N1.

you'll want this system...especially since it's cheaper than the HKS...trust me
