My AP Exhaust Problems!
 

Well so far ive had nothing but nightmares with this exhaust. Below i will describe why.

I purchased this exhaust from Vivid Racing about 4 months ago, the first time with the exhaust at the track the mid pipe connecting to the rear section of the muffler came loose causing it to bend and scratch as it dragged in the track it held together which was nice but it was almost completely ruined. First i thought that i had not tightened it correctly so i tightened it as much as i could again, and even the local track mechanic checked it out and said it was good to go.

A couple of weeks later i noticed the exhaust was leaking by the clamps since it had black exhaust snoot around there and after another lap session the exhaust came loose again as i was coming back into the pits. I tightened it as much as i could and noticed now that it was starting to leak where the rear section connects to the right exhaust canister but i checked it out and it was tight so i paid no attention to it. My last two track days have been night mares between the mid pipe and right section popping off every 5 laps (btw this caused my oem rear diffuser to burn). I also noticed that my catback had the logo on the right exhaust tip and it had nothing on the left exhaust tip, i guess it slipped by them when they shipped it but at 800+ dollars this should be no excuse.

I decided to contact vivid on Monday explaining the problem and sending them pictures of the exhaust, keep in mind this is not my first track car and i have had nothing but great experiences with greddy, hks, borla, and tomei at the track but i had never tried AP. Sure enough their sales manager got back to me and told me he was going to get in touch with AP and fix this asap.

Well he did get back in touch with me but offered me to send it in and he would have it repaired and sent back. Now my main problem with this is that i cant have down time i have a couple track days that i have paid for and they are non refundable, so sending in the exhaust means loosing $500 bucks in my track fees plus the shipping of the exhaust both ways which imo is in a non repairable condition, its going to cost me almost the same to just purchase a new exhaust. Sadly i cant run my oem exhaust because i threw it in the trash thinking i would never need it again. My mid pipe is bent, the welds on the clamps that are integrated to the rear section are torn and so is the right rear section, it leaks, its scratched since it dragged on the floor and its missing a logo on one of the exhaust tips, so i really dont know why they would want to repair this exhaust. Its not in the garbage yet because i may have to just take the clamps off and weld it at a muffler shop to keep me from missing my track events until my new invidia exhaust arrives. I was also notified by their sales manager that since i track my car they could not issue a full warranty replacement. So to me thats not standing behind your product, a good exhaust should be made to take abuse in the street and on the track. Way to treat a customer that has purchased with you guys for over 4 years, and im not talking intakes and shift knobs im talking about parts for 2 full track builds and at least 3 other DD vehicles ive spent a good amount of dough with them. I really miss their old sales guy Billy, he always took care of me.

I had a similar problem with a tomei turbo outlet pipe on my sr20det the thing cracked and i was issued a new one by tomei no questions asked after it cracked after only 2 track events, or my boomba catch can that the glass cracked and they sent me a new one as well no question asked. Shows you the difference in customer service.

Here is my old evo x thread of the boomba catch can

Anyways had to vent and let you guys know what my experience has been, i hope you guys do the same and share your nightmares on the forum so we know what we are purchasing.

First track event my exhaust popped off here are some pics of the damage, you can see the clamped scratched up a bit while it dragged as well, so this would stop vivids claim that i might have hit something!:

You can see some exhaust snoot where the exhaust clamp is leaking, and yes i have double checked and triple checked that its tight.

I don't know how they will fix that dent. You must of smacked it hard.I would of asked if they can give you a new or "refurbished" and cross ship.

Worse comes to worse I would just run the stock exhaust. I don't see it doing anything damaging to your tune.

Well it popped off during a lap and it banged on the floor for a bit and dragged thats why its scrapped, on my build thread i posted about it. I thought it was my mistake because maybe i did not tighten it enough but the track mechanic mounted it again and tightened it and approved me and it popped off again.

Here was their response, direct copy and paste from the email they sent:

"I spoke with Agency Power and they have offered to take a look at it and can repair the damaged unit, but with the issues you've already had with the system on the track we would not be able to supply a warranty replacement "

"Agency Power does stand behind the product by all means, although with the situation of your system falling off once and taking track abuse this would need to be inspected and repaired rather than replaced as a warranty. I have attached a picture of a new exhaust and its integrated clamps, it is unheard of to see this over tightened to the point of ripping off. This is the situation we have and I apologize for any issues this may have caused. The other damage to the system has caused concern, this does not seem to be an issue of an exhaust that will not handle abuse, although every component has its limit."

I used to work at HKS and never heard of anything like that at work or on my own free time. I've never heard of an exhaust getting damaged from purely "track abuse". An old or rusted or off-track experience or improperly installed exhaust would be a good reason to void a warranty replacement but it doesn't seem to be the case.

Basically it would be nice to hear why Agency Power does not supply a warranty replacement.

I'm not really understanding why you tracking your car has anything to do with a defect in the exhaust. What if it fell off while driving around and it got scraped? No where in their limited warranty filing page does it state that tracking your car voids anything. If they void warranties on this basis they should atleast inform their customers.

I have the same exhaust, i am havin a power loss issue that i just started investigating. I really need to put the car up on jacks and make sure I don't have the same issues you do. I have no plans of ever removing the exhaust so do you think welding it would be okay. or do you think it would make it too difficult to install a high flow cat and headers down the road? I really love the sound of the exhaust but I'm scared to have problems down the road.

I would like to hear it as well man, i have been very transparent and honest in my build thread and i posted about the exhaust coming loose after my first track event. I actually gave them the benefit of the doubt but when it came off again and i saw leaks in the clamps i knew it was the exhaust. I have 4 witnesses that were at the track when the exhaust came loose. The sales manager even said while we were talking on the phone that why was i mad at the exhaust if i was happy with it before, i was happy because i had not realized the quality of it and i gave them the benefit of the doubt the first time it came loose and even put on my build thread that it might have been my mistake. Then after i got pissed he went on and said that i could have hit the exhaust loading my trailer etc thats why they wanted to see it. Sucks that after being their customer for 4+ years they would doubt that i would lie about something like that just to get a new part now. I had the opportunity to send it back and get it fixed and i decided to just suck it up and rather bought a new exhaust today from evasive so thinking i would do it to get a freebie is ridiculous on their part.

Racing is the root of all evil!!! (tongue firmly in cheek)

Slip joints are utter garbage, we had the same problem with the clamp always letting loose on the Solo Performance exhaust on the Solstice. Our solution was to buy V clamps and weld em on. The bonus here is we had 2 rear sections in case we had issues with meeting sound, so they each had a mating collar in case we ever had the need to switch, it was super easy.

Buy a pair of bands, a clamp, and you've got an interim solution for your track days, it could be a long term fix, but that sucker looks pretty mangled...


But yea... I read their response as "Agency Power does not design their product for track use"... so if you plan to track the car, probably should look elsewhere to those companies who do design for track use.

The problem with my leaks are on the rear section , the front connection to the cat seems fine since it mounts as the stock one would. The problem is the rear slip ons, i think their clamps are not tough enough and the pipes are to short so there is very little pipe inside the clamp which causes it to leak and pop off. I guess the heat from the track really gets to it. I also have their first version of this exhaust i know they revised it later on because John who used to work with them told me so, this might be why also only one of my exhaust tips has the logo.

OMG yea, that is a TERRIBLE design. The clamp is to CLAMP and retain, not meant to be a small joint pipe and take load. :lol:

Sounds like someone needs to invest in a header back and drop ap quick.

I agree, on the street it might be ok but at the track where the car is constantly under WOT and absorbing bumps this can become a huge problem like it did for me. Thanks for the link on the V band clamps :).

I purchased an invidia exhaust today and have a motiv concepts front high flow cat which works awesome, i was about to buy AP headers but decided to wait for another company to make some after seeing what happened to my exhaust and the way they stand behind their products.

I sold my GT-R with 24k miles and that car had a lot of track abuse on the HKS exhaust and not a single problem, i installed it my self as well.
