Well I decided to change out my exhaust system from the Topspeed Pro 1 to the KCR (HKS style) exhaust. I did this because once I installed the MR long tube headers on my G, there was so much rasp, it ruined the sound IMO. So being that my G has always been on a budget build, I decided to go with one of the "more expensive" clones on ebay. The seller has almost 26k feedback responses and a score of 99.1%. You can find the exhaust here. http://cgi.ebay.com/ebaymotors/Dual-...Q5fAccessories

Well let me get started. The install went suprisingly smooth. Took about 30-45 minutes. It was a little tedious simply because of all the connections on the whole system. I got everything hanging by a light torque of the bolts, then use a floor jack very gently to help suspend the exhaust off the k-frame and up over the rear sway bar (this is crucial to do otherwise you will have all sorts of metal on metal rattling and misaligned tips). Once everything was in place, I gave all the nuts/bolts a final german torque (goodentite) Everything fits very very well for the most part (just a 1/4 inch from being perfectly aligned in the factory exhaust slots in the lower rear bumper, but its not even noticiable).

PRO'S $519 SHIPPED! You cannot beat this! All the welds look GREAT!. No pitting, no excessive heating when it was tig welded. The polished stainless looks great and the tips are 10x better looking than the Elohite X02 exhaust. The fitment was almost right on. The sound is amazing None the less! It took out all of the rasp that I had with my Topspeed Pro 1 setup and looks 20x better. So if your running long tubes or test pipes, this is what you want. I am now rasp free! There is virtually no difference between this and HKS Hi Power other than the location of a brackett or 2 and welded caps on the dead chambers. But if you compare this system to the HKS, if you look at the dead chamber above the right muffler on the HKS system, the bracket that stabilizes the muffler with the dead chamber is on the outside, whereas on the KCR its hidden behind it so you don't see it which is all for a cleaner look IMO. Essentially it has the same sound as the HKS, just a little deeper. HKS is a stainless steel exhaust with Titanium tips. KCR is a polished stainless with polished stainless tips, so you will pay quite a bit more for the Ti HKS.

CON'S Very tedious job when it comes to making sure everything is aligned from the Y-Pipe all the way back to the tips, especially where the exhaust goes up and over the sway bar on the passenger side and a close tolerance near the rear differential. I'm a perfectionist so I had to make sure this would align the best as possible so it took some crawling back under the car a few times using a floor jack to suspend the exhaust off the k-frame and align it perfectly at the sway bar location and where the exhaust tips come out the rear. You be the judge and let me know


All in all, let me say, the main reason why I got this exhaust was to get rid of the rasp. The Topspeed Pro 1 only had 1 resonator on it. KCR has 2 and 2 dead chambers. Plus it just looks sick!

I give this exhaust system from KCR (M2 Performance) a 9/10 in terms of build quality, alignment of all components, sound, and looks. I am a very satisfied customer and I would reccomend this exact system over Elohites in terms of quality. If your on a budget like me, I reccomend it over HKS. It's virtually the same exact system, 3/4 of the cost cheaper.

I will post a video within the coming weeks, in the mean time I have provided some pictures of the build quality and alignment. All comments are welcomed!

 

Can you push them to the side at all?? they're a bit too close together, doesn't match up with the bumper cutouts.

Other than that it look really nice!!!

 

Thats as close as i could get it. Its only 1/4" off though, not bad

 

The HKS is not titanium...only the tips are.

 

Your right, I had to double check, I thought it was full Ti

 

Glad it worked out. I'm surprised it took out the rasp w/ just the H pipe and no X pipe

 

i am also surprised. cause even the hks alone has some rasp.

 

Im very happy with it, The long tubes ruined the sound of the Topspeed Pro 1. 1 resonator just wouldnt cut it.

 

how do you know which one is which on ebay..there so many of them..but other than that..i like it..thinking of getting me one..hmmm...haha

 

I posted a link to the one which looked best IMO and who has sold the most with the best feedback

 

awesome review dude, you may have just pushed me over the edge to pick it up on ebay. im assuming with cash back it was somewhere around 400-450 shipped????

only thing i dont like is the holes on the tip, but ive seen many other exhausts with those as well

 

looks nice i might consider this..but do you think it would sound fine with OEM Cats? Did you feel any preformance wise???

 

Nice! I think i might have to get this exhaust now.

 

It will sound great with oem cats! YouTube 350z X02 exhaust or g35 X02. Essentially they all sound the same, i just think the tips on the KCR are of higher quality than Elohites X02.

 

$519 shipped! Its really tough to beat it.
