I good friend of mine got a new exhaust over the weekend on his G35 and gave me his old HKS exhaust. I didn't know how bad they were until they were off the car. I will be fitting this on my Z by cutting it shorter after i'm done.


Here is a picture of when we took them off.



i tried to clean it up by just a rag and some nice metal polish but i didn't look any better from the picture above. It was so bad, i was thinking of just scrapping this project. the rust was just too bad. and there was salt damage or something

Symptoms were :

-bad rusting
-pitting in metal
-scrape mark on the bottom
-stained oxidation
-oil/dirt/etc stuck on there

I'm not done yet..but have about 3 hours into it. Still need to do a bit in the crevices and the rest of the piping and such..ran out of materials. I'm confident now since this was the worst of the two pipes





The following steps were used. I had to bring in the buffer for this one.

-Clean off pipes with glass cleaner
-sand with 600grit
-sand with 800grit
-sand with 1000grit
-sand with 1200grit
-use steel wool
-use high speed buffer with metal polish on an orange cutting pad set to 6
-repeat until shine desired

 

cant beat free. Looks good so far

 

looking good so far, its gunna take some time looks like you got the hand of it

 

yeah he let me have it for free if that's what you are meaning. i know you got something to trade for it

He has long tubes with the exoticspeed exhaust and it's the best sound i've heard to date in person. i drove it around too, sounds rediculously nice.

 

NICE...


in for finish!

 

please get a vid. I love hearing diff exhaust tones.

Im also thinking of either selling my AP or storing it in the building of rmaybe a rainy day. Super pumped for my custom exhaust.

 

here is the video. does it NO justice. my camera can't capture the sound at all. It's louder than pikespeak's AP with no test pipe, at 3 rpm , it's about as loud as my nismo was with kinetix res test pipes redlining..lol. He also had nismo cams and and a redline of 7100. It's deep..not too deep, its loud on the outside, quiet on the inside and sounds just alike a motorcycle when revving and driving around.

^- sounds real good! i love that camming sound.. cling cling cling lol... if you're gonne use the HKS, I hope you open it up @ the H piping and fix it up a bit there as well, if your going through the trouble of shortening it.

 

you mean that divider thing they had a debate about while back? i wonder if i should just throw an x pipe on there.

 

Wow man... Looks gorgeous.

 

Consider yourself 1000 bucks richer, looks amazing. I really do love my HKS, the youtube videos made me actually hate the HKS at first.

I can't wait to get everything on my car looking as good as new, including a thorough cleaning of my HKS. Anything special to look out for when cleaning the tips to not mess up the burn?

And that G35 does sound like sex, I could only imagine how it sounded in real life.

 

Well done. No kidding. A little elbow grease.

 

You're doing a damn good job with the work.
This is a sign from god for me, my HKS is almost as bad.
Thanks for the process write up.
I'll get working on my exhaust as soon as it's not 40 degrees outside.

 

Keep up the good work, its looking very nice

 

Great progress thats tough work

 

love a good comeback.

 

Wow! there may be hope for my nasty discolored Shockwave axle-back.. Wax-on, wax-off, Danielson.

 

Sweet Jesus... Great job....

My AP has seen better days buy I think I'll do this to it n bring it back to life....

Great work man keep it up!

 

Very nice superblack

 

Nice job! Do you still have the Nismo or did I see in on Juan's car? I want a Nismo next...
