Bodyboarder81 Posted May 14, 2015 Posted May 14, 2015 I'm pretty confident that its still rasp from the decats ..... Mine does this and it's fitted properly and 100% not touching anything ( Horsham developments double checked everything ) the braces will help a bit but I've read this is just a trait of decat pipes . If you fit a true dual system ( invidia/ ark ) then this gets rid of the rasp but the true duals are louder/ drone more . I've ordered the art pipes to try and combat some of the rasp from my miltek ( conventional y pipe design exhaust ) ill let you know nic if this helps . Annoyingly the berk decat pipes come with the tabs on to install the brace !! I also have some berk HFC if you want them nic? Quote

That's if we're talking about the same sound - 11/12 seconds and 18/19 seconds. Quote

That's if we're talking about the same sound - 11/12 seconds and 18/19 seconds. Not sure I agree - as I said earlier - it sounds like a significantly worse version of the noise I get from my exhaust / HFC combination and I definitely have no issues with knocking or loose parts. If you watch the video you will see that noise appears to occur when the car reaches the limit he's revving it to and just before the revs start to drop down again. If it was a knocking issue I would expect to hear the noise as the revs climb - not just when they start to fall. Perhaps a loose joint or something is making it worse, but I think it's an issue with pronounced rasp. I guess the only way to find out for sure though is the checks that have been suggested. Quote

Must be a 370 thing then My cars king of rasp, as it sounds like a poxy civic with the headers on And it doesn't make any noise close to that :S Quote

Must be a 370 thing then My cars king of rasp, as it sounds like a poxy civic with the headers on And it doesn't make any noise close to that :S Probably doesn't help that 'rasp' means different things to different people but here's an example of what somebody terms a raspy BMW exhaust - if you listen carefully a similar sound occurs when the revs start to drop at 48 seconds - a sort of buzz - it's not as loud as on the OP's car but pretty much the same sound. It does seem to be pretty much par for the course to expect some rasp when combining an after-market exhaust with anything other than stock cats on the 370. I never got it at all when I just had the Stillen exhaust but it does seem to happen a bit since I added HFCs. Good thing is the overall sound more than makes up for it.

Bodyboarder81 Posted May 14, 2015 Posted May 14, 2015 It's also a known that the HR engines ( 50 and 70 ) are more raspy . Remember that nic is charged , so this will increase the rasp even more due to more pressure and gasses flowing through it . Quote
nissanman312 Posted May 14, 2015 Author Posted May 14, 2015 I have conciderd putting the stock cats back in as stillen says it's OK with them in Quote
Adrian@TORQEN Posted May 14, 2015 Posted May 14, 2015 (edited) Somebody please slap him! How many times we've covered this subject with the OEM cats on Stillen SC cars... Oh, God! Edited May 14, 2015 by octet@TORQEN 1 Quote
Grundy Posted May 14, 2015 Posted May 14, 2015 Matt - what exhaust are you running ? Mines custom with Decats and Stillen headers - Quote
Grundy Posted May 14, 2015 Posted May 14, 2015 I have conciderd putting the stock cats back in as stillen says it's OK with them in Hasn't the car just been tuned? If so you're going to need another one if you're switching them over. Quote
nissanman312 Posted May 14, 2015 Author Posted May 14, 2015 Yes mate I know Somthing needs doing I'm almost covinced it's the back box but I'll investigate satarday Quote
nissanman312 Posted May 15, 2015 Author Posted May 15, 2015 (edited) Anyone in here had experience with the stillen exhaust? Edited May 15, 2015 by nissanman312 Quote
ChrisB Posted May 15, 2015 Posted May 15, 2015 Only bit of Stillen in my exhaust is the Y pipe.. My VQ35-DESC setup is OEM headers, Fast Intention HFCs, Stillen Y, and the rest Fujitsubo Legalis R (stainless) with 4" tips. Love it personally: vvvmmms at 2750-3000 RPM cruising rather than drones on uninvited. Yowls at me when my boot is down People comment that my car sounds good - I agree Quote
nissanman312 Posted May 15, 2015 Author Posted May 15, 2015 See I think it's my back box doing all the nasty noises could it be worth trying somthing else with the rest of it or would it not pair up Quote
sipar69 Posted May 16, 2015 Posted May 16, 2015 (edited) Anyone in here had experience with the stillen exhaust? Don't know who I bother sometimes . Me...I've got a Stillen....I mentioned it earlier in this thread I'm not supercharged but here's a review if you're interested. Will and Colin are also fans of the Stillen. It's not overly loud but a great exhaust. If you don't run stock cats you can expect some rasp but nothing as loud as you currently seem to have. http://www.350z-uk.com/topic/83723-my-nismo-given-the-cobra-and-stillen-treatment/ Edited May 16, 2015 by sipar69 Quote
dajw Posted June 1, 2015 Posted June 1, 2015 (edited) Nic you need to hear my exhaust — It sounds so good! Motordyne ART pipes, Ark GRiP system. No rasp, great sound, just a bit of stainless 'zing'. Sounds expensive Edited June 1, 2015 by dajw Quote

nissanman312 Posted June 1, 2015 Author Posted June 1, 2015 I know I've gone with the invidia just to let you know I went out with a member the other day and liked the sound of it so I'll try it out for a bit Quote
Clarkie Posted June 2, 2015 Posted June 2, 2015 OEM headers, Berk HFCs (altho i'm pretty sure they're empty by now ), Stillen Y pipe, the rest is Nismo. Sound is divine! Quote
