Thread: High rpm rattle(Honda sound) gross

At like 3k(rpm) my ser sounds like a Honda... Why is this?

Something is loose... Rev it from the throttle body and see if you can isolate it. Better than that, if you have someone else to help you, try and have them rev it to that and listen around for it. Tell us where it sounds like its coming from and we'll go from there.

first off dont forget your a 4cyl, like a honda. even k20's sound sick.

i used to think it was because honda owners just half assed everything in life and those were exhaust leaks or loose gaskets rattling between surfaces in the piping.

after checking all surfaces and piping for loose shit, consider this:

its really due to the exhaust tuning which is basically all these combined: motor, the diameter of piping, length of the piping, shape as it goes are bends or curves, various bottle necks/ restrictions in the exhaust system, type of muffler, muffler size, the frequencies the muffler blocks.

if one or most of these are lacking, too big, not proper, bad or not the right part for the job then that creates rasp (honda sound), rasp is exhaust wave turbulence that is gas and sound in conjunction. anything to upset the frequency of the exhaust gas/wave will create rasp

thats why when HKS,Nismo,fuji,Greedy (greddy lol) make exhusts they never ever sound raspy, thats bc they tuned the exhaust to block out the frequency of rasp that the motor makes in conjunction with the piping. yes it has rasp, but they tuned it to where u only hear it at a rpm or load the motor will never see or its a inaudible frequency, ect

I had my greddy on and it still sounded like that.. But now I smashed my greddy on the floor :/ running it without muffler. At 3k I get the rasp

u live in the north. check for rust, and replace your exhaust gaskets and get a chambered muffler welded on if you dont want rasp

lol what the hell is this thread about, your not running a muffler, and you wonder why your shit sounds funny? HMMMM?? could it be that YOUR NOT RUNNIN A MUFFLER? lol

x2.. I ran straight from the cat and it was raspy but on my 200sx I have a resonator with 2.5" piping, no muffler and I have a perfect tone to it

I had a lot of rasp on my 2.5 vrs on my ser, I added a 27" resonator after the cat and no more rasp, also I didn't feel any power loss/gain

i hate when peoples car sound like shit they say it sounds like a honda

No offense to hondas my friend I love Thr preludes...and even when I had the muffler it rasped
