Needless to say we see all kinds of things come through our shop. Some of them are just plain hilarious. There are companies out there pushing parts that have no clue how to build something. Other companies are making claims to have this or that and just flat out lieing.

Above all I like to think we are honest here and won't sell things that don't perform or sell parts to a guy that just doesn't need it. For example a guy calls and wants 1,000 cc injectors for his stock turbo'd EVO. He is going to be warned that isn't the way to go. Too many other places will not only sell the wrong combination but even SUGGEST that you buy it!

Below is a picture of an EVO exhaust. Manufacture sells it as a 100% stainless steel system. Well as you can see from the pictures it is not. Check out the completely rusted flanges. We checked these out, as they are only a year old, and they are nothing but mild steel stamped flanges. The flanges our system use are 100% 304 SS, will never rust, as with the balance of our system. The Magnaflow mufflers are also advertised as 100% stainless steel and we use them but there is a catch. The body itself is 304 grade SS, what they don't tell us is the tubing that runs through the middle is not 304 SS, it is 409, which is a lower grade SS that does actually rust over time. It is what the auto manufacturers typically use on the stock exhaust systems.

Here is the rusty picture:



This is one of many systems built like this. Just the first one we have decided to take a picture of.

Makes me glad I went with a quality exhaust like yours, David. Thanks, and keep up the good work.

 

Here is a picture of another mess. This is just a flat out joke and the manufactures should be sued for selling this in my opinion.

Had a customer come down last week. Has mostly our parts on the car and our GT3071 turbo kit. Car ran like crap and wanted me to install the HKS VPro on it. Car would literally not run or idle without stalling. No power.

We install a set of 264/272 cams, the V Pro, MAF pipe and a new filter for him. Put the car on the dyno and start tuning. It takes me quite awhile to tune with the V Pro as I don't do them everyday like I do the AEM EMS. Also no boost correct and you have to be careful as there is no knock control. Anyway pull after pull it gets better. I started as something horrible like 114 whp and ended up at a rock steady 21 psi, 93 octane and 286 whp. I was no impressed. I wanted to atleast crack 300 whp. I have to keep the tune conservative as there is no margin for error. Without any knock control one poor tank of gas can destroy the car.

Anyway, him and I talk about the problems. I finally ask what exhaust is on the car and he tells me. I see there is a 3" cat on it and it is small. I suggest taking the exhaust off, installing ours and trying to run the car again. He agrees.

Once the car was on the lift I looked into the muffler before we removed it. I said a large sentence that contained mostly four letter words, I was in shock! The inside diamter of this advertised 3" system was SMALL. I mean like 2.25" small!!

We pull the system off and I get a set of calipers to measure it. What this company does is uses 3" tubing all the way to the muffler. Then they BUTT weld the 3" tubing to the back of the muffler, so it appears to be 3". What is actually there is a 2.25" inlet that is covered by the 3" tubing!! It continues 2.25" into a tip that is stepped down to 2.25" and the tip covers part of the outlet to further make it worse!!!

Below is the picture of the outlet of the muffler, this is actually slightly larger than the ID of the muffler.



We put the car back on the dyno. Unbelievable the difference in spool up. Car hits HARD. Now we run into another problem. With the boost controller set exactly as it was the car is now boosting 30 psi instantly. I turn the controller all the way down. Still goes to 28 psi. I try two more boost controllers and then try to run the wastegate straight, still 27-28 psi. The car instantly gains over 20 whp at 5500 rpm and is climbing until the safety features I set up in the VPro catch it and kill it. What we ended up running into was boost creep. The internal wastegate in the GT3071 just could not control the boost.

This brought us to a crossroad of either installing an external wastegate or installing the junk exhaust again just so he could get home and drive it.

For now with money and time being an issue the customer chose to choke the car's power off and we put the junk exhaust back on the car.

He is coming back as soon as the funds and time are available. I would guess the difference is going to be close to 40 whp from swapping out the exhaust at the exact same boost pressure.

Sometimes you don't even get what you pay for and in this case this company is robbing it's customers.

What mfr's exhaust is that?

 

As much as I am bad mouthing them I'm not sure, legally, it would be a good idea for me to say who either company is. Any lawyers in the house?

I think the main point is..............buy ours

Not a lawyer, but your only posting a factual statement about pipe dimensions. What is the saying I learned in B Law, "truth can not be slander or libel". You should name the manufacturer.

 

Dave, c'mon, dont make me get the truth squad over there, just say what it is, or at least give us a hint. I know I wouldnt sell a junk exhaust like that!

 

Exactly.

 

Maybe give us a hint...ebay?

 

theres no legal ramifications if you just name the manufacturer, your not slandering, your stating facts.

Fact: The 1st exhaust is not 100% SS
Fact: The 2nd exhaust is not 100% 3"

those arent saying bad things, so just post up the manufacturers so people know to stay away

 

Please do not push it with the manufacture's name. DB is doing you guys a favor by alerting you to the potential problems (caveat emptor--buyer beware). Ask questions before you buy. Now you guys know the right questions to ask your vendors.

I have a Buschur catback with the Magnaflow muffler (keeps johnny law off my case). What I did was to use some silver muffler paint on the pipe ends to slow the rusting. Inside, I can't do much about that...The piping and flanges are first rate. And very light too!!!

 

Great job David thanks

 

Why even make a post if he doesn't give the manufacturer. He could have gotten an ebay exhaust and 99% of the others could be just fine. If it's one of the more famous names, people will start to wonder if they should go forward with brand names and maybe finally start buying domestic **** too.
This way, everybody will say, it's surely not mine because mine is JDM goodness, best thing after sliced bread and keep buying what they do (and possibly learn the hard way).
I'm sure if mine rusted I'd post the manufacturer and model along with all the pics so I save people money and trouble of going through the same deal.

 

how will people know to stay away then???

I wouldnt be surprised if the first exhaust that rsuted was HKS Hi Power, because they are only mild steel to begin with. AND ASKING A VENDOR TO TELL YOU HIS STAINLESS EXHAUST WILL RUST WITHIN A YEAR OR HIS 3" EXHAUST NECKS DOWN TO 2.25" IS RIDICULOUS

 

the more popular modifying cars gets the more companies are going to jump on the bandwagon and crank out cheap products just to cash in on the large market. It would be interesting to know how many are really testing and providing good products though, maybe you should post what exhaust those were! We might all be suprised.
