ok, I just got mine fitted this morning. The weird thing was why my one sounds extremely loud as civic with big muffler comparing to other ppl who have same system. been hearing some sound clips of that from youtube and it does sound nice. what could be the problem? I paid extra $100 for sus304 on tips and muffler
also had fittment issue with left muffler which is touching the bumper
any advice will be appreciated!!!!!!!!!!!!!!!

 

sound clips of this for comparison to others?

 

yea, let's hear some sound clips of yours... it definitely shouldn't sound like a ricer civic. should sound deep and mellow and not too much louder than stock. where did you get it from? ebay or a vendor? and what's sus304?

 

lol, I took it off for a day only then sold it already.
Dammit, lost a lot on those ****. I'm not sure my one is faulty item or material different, the sound is just so wrong.
I bought it off someone who organised group buy from Australia 350z forum.
The seller said sus304 is better material than other stainless steel...
but i noticed the rear muffler only 2 inch which is no good coming through from 2.5 to 2

 

should've just bought the hks and called it a day

 

^ no, the X02 is a great exhaust... he should've just bought it from a reputable vendor (Invision, for example).

 

The vendor makes no difference...unless you can prove to me that Invision themselves somehow modified the exhaust to make it better.

 

well, the vendor he bought it from claimed to use sus304 () material... that means it probably wasnt produced by the same people Invision use (or on a different assembly line, at the very least).

 

If I'm not mistaken, the xo2 exhaust uses sus 304 stainless steel. The OP got ripped off if he had to pay an extra $100 for something that all the replica HKS exhausts have. There's only one replica, and one authentic.

 

Next time buy the real thing (HKS) and stay away from cheap imitation HKS exhausts (XO2, etc.).

 

have you tried adjusting the hangers?

btw - all hks replica exhausts use sus 304 stainless steel.

 

yes, tried adjust everything, but came out just a bit ok. anyway, it's off already. I really think got rip off by that seller. he told me indside of muffler and tips are different material!!! also there are some different manufactory made those replica hks exhaust which there are on ebay. the different is some offers one year warranty but some don't that was what he said
omg, i lost $300 on this and had it for a day only

 

There may be more than one name for the HKS replica exhaust, but they are all from the same manufacturer.

 

where can u get it...i might get the hks replica maybe
