My oem exhaust tubing measure as a 2.5 OD on my G35. I need to crawl under the car and see if it's all constant size. It looks pretty well made really.

 

I'd go with the 70-something in box Invision mentioned for the HKS. Probably , 60-some unpacked, if that, HKS uses a lot of packaging. I knew the 31 lbs on my shipping form couldn't be right. I think they only printed the weight of 1 of the 2 boxes on it. Honestly, handling the pieces seperately during installation really gave me no idea as to total weight, but I believe someone that sells them would know the total weight they ship.

 

litlechina- where did u get urs from? Invision Performance does not like responding to people... so i have to look for other sources.

i got mine from etd motors on ebay...

by the way...after a few days the exhaust has broken in a bit more and has gotta slightly louder inside the cabin.

 

i just ordered mine from Invision, seems like it should be here by saturday, nice little weekend thing to do.

Now when u say it's gotten louder, is it like uneasy fartcan loud, or loudER at WOT

 

I have the real HKS exhaust. I am really curious to meet up with somebody who has one of these and compare.

 

+1

 

Interesting.

 

i made a video of my stock exhaust, will do another one when i get my XO2 on. Promise!

 

I just ordered from invision as well and got really great service..I think the magnaflow x-pipe would be a great addition to the exhaust...might even quiet down some of that cabin noise and a little rasp and even add a little to the low end...

 

EEEEEEEE- rasp? without test pipes?

 

is there any rasp with the hks ko?

 

im also interested in how the metal holds up...last thing I want is rust or any severe discoloration.

 

rust is out of the question, since its 100% stainless steel. I was talking to Louis over at Invision and found out that it comes with a 1 year full replacement warranty. Seems like a great deal. I think it's better to go with this then the HKS. I'm gonna test this one out myself

 

He has test pipes though

 

no rasp at all...if u like a deep and mean sound this exhaust is good...there is a little bit of drone ince it has broken in tho.

 

In my XO2 exhaust I to have very minimal drone, but that is maybe because I have test pipes too. I can't complain when I had the Ingen it was really abnixous with test pipes.

 

What kinda test pipes are you running??? I know people that have put the magnaflow muffler x-pipe on the injen exhaust and they say there is a decrease in drone... I might try this!!!

 

I've had mine for a few weeks now and it seems to have gotten quieter despite running turboxs test pipes. The other day i replaced the tips with real HKS TI tips so now no one can tell the difference MUHAHAHAH
