warranty consequences with aftermarket exhaust - Page 2 - Porsche General - PistonHeads UK

i am considering fitting an aftermarket system to my 996tt which has extended porsche warranty but have concerns over the effect it may have on any subsequent warranty claim. porsche commented- any subsequent claim under the warranty would be discretionary and scrutinised if the event the exhaust could have contributed to the reason for the claim. whilst i appreciate this is an open-ended question, what potentially could go wrong as a result of fitting an exhaust? has anyone found themselves in this position?? thanks

OK so it wasn't on a porsche but I nearly fitted quad pipe aftermarket boxes on my SLK. Luckily I changed my mind, as two months into ownership, one of the cats split. System replaced FOC, but they would have told me to bugger off if I'd had the modded boxes. £1200 thankyouverymuch. Just something for you to consider.

I am the biggest promoter of the OPC warranty on here. If you get aftermarket exhausts, I think it extremely likely that they will blame engine problems on it, fold their arms, sit back and make you go to Court to enforce the warranty. Morally this may not be right, but at the end of the day if they say no, the burden of proof will be on you. I wouldn't risk it.

It is risk, I would grant you. But I have made a lot of modifications to my GT3 and OPC Guildford have still honoured warranty claims. More specifically, the engine has been re-mapped and it has an aftermarket exhaust, inter alia. Despite this, new coil packs have been covered under warranty. I suspect if something more serious happened, I may have an issue, but I get the feeling that unless the problem is directly related to one of the modifications, they will do their best to be helpful. The other point is that Porsche have agreed to extend the warranty (two years running) in full knowledge of these modifications - I have worked on the basis that full disclosure up front makes it easier to have the conversation down the track. But, I will end where I started, it is a risk. Kind regards Steve

When you say Porsche have agreed to extend the warranty, do you know that your dealer is actually tellng the underwriters about your mods. Mapping is an all time no-no for any claims, against any piece of the drive train. Its not worth paying £900 a year to have 6x £70 coil packs insured. I'm also a big fan of the warranty, but you have to be realistic and appreciate what the underwriters are covering. I the exhaust produces no more power then it should be OK, except for the exhaust itself being covered, obviously.

i spoke directly to Porsche HQ and asked the same question as i'm exactly the same mind set and was told that it would be fine. However i would want more information ideally in writing before i spend my 2k on an exhaust before i potentially null my warranty.

Put £1,000s of warranty claims through on my old 996 which had an aftermarket exhaust.

i would imagine that if the exhaust was linked directly to a warranty claim then fine but how can putting a 2k exhaust potentially harm a 25k engine designed to be driven as your average TT does?

I would say your safe, I had an aftermarket system and had claims aslo. If anything the aftermarket system is less restrictive so you would be far less likely to be putting any internal stresses on the engine.

said: When you say Porsche have agreed to extend the warranty, do you know that your dealer is actually tellng the underwriters about your mods. That is irrelevant. I am contracting with Porsche and how they lay off their risk / broke the risk is their business. I have documented the disclosure, and the OPC and I had a grown up conversation about the potential risk of future claims not be honoured. They treat me, as they should, as a good, long standing customer and I trust those relationships. In return, I am 100% honest with them and never "try it on" (and I'm not saying anyone here suggested that). Seems like a sound policy. said: Mapping is an all time no-no for any claims, against any piece of the drive train. I assume that means you have evidence that every claim ever made with a mapped engine has failed? If not, you can hardly be so definitive. As I said, it is a risk, but I believe my OPC would consider the fact of any causal link between the mods and the problem at hand before deciding whether to honour the claim. said: Its not worth paying £900 a year to have 6x £70 coil packs insured. I hardly said that (although the GT3 coil packs are rather more expensive). Most of the reason I keep the warranty is to protect against electrical faults, which can be pretty costly. I accept the risk of drivetrain faults not being covered. Kind regards Steve Edited by stefan1 on Thursday 22 February 18:27

Don't forget the OPC gets paid for doing the warranty work, so they are hardly likely to try to refuse the jobs. Although, large claims are more likely to be scrutinised by Porsche (or whoever ultimately backs the warranty and pays out the claims) - sometimes this will be simply the return of the faulty parts replaced, other times they may send someone to the OPC to inspect.

thanks for the comments. very useful. i have decided to buy the exhaust-i re-read my own post-looked like im worrying about worrying, the sky could fall in tomorrow!!!

what exhaust have you decided on?

milltek in a couple of weeks.

Anyone tried AWE muffler system out here?............Sounds fantastic on the Cayman S with a reported 11bhp+ on the normally aspirated engine.

Evening all, I'm just about to / almost ready to pull the trigger on a 991.2 gt3 which has a akroprovic exhaust and at this moment it has no Porsche warranty. it has been for a vehicle health check at Porsche Reading and needs a set of plugs and aircon every thing else green but they did say it can't have a Porsche warranty due to the aftermarket exhaust do individual OPC's make that judgement call or is it a national Porsche policy not to offer a warranty when aftermarket items fitted? I have been offered a 6 month warrantywise one on the sale but not sure what they are like although reasonable good reviews .... in essence would you go for it or not. all comments appreciated and thanks in advance

They won't cover it. The car will need a 111 point check and one of the boxes is all Porsche parts. Photo attached from one I had that other day. For those who say no problem. Maybe yes maybe no. If the car is in continual warrenty ( no 111 check ) then cover will be in place but I bet a warrenty condition is all Porsche parts. Now will you get found out ? Will the dealer play ball? Maybe. But contractually you won't be on the winning side

Porsche refused a warranty on it and I pulled out of the sale. The vendor bought the correct part from Ebay (not expensive) had it fitted and the car now has the Porsche warranty and I own it. I wouldn't buy without the warranty and, in my experience so far, Porsche won't approve a warranty with non Porsche parts fitted.

There is no generic answer. The OPC you use is the gate keeper for warranty claims…it is largely down to them what they think is relevant. I’ve had BBX wheels on my 991.2 GT3 for four years. I’ve extended the warranty two or three times with them on and claimed for PADM on both sides. Wheels have never been mentioned. A different OPC may take a different view. In theory I absolutely should not be able to renew the warranty with the wheels on.

You can if it is on warrenty and hence no check.

Neither Harris or Biden have had the common decency to congratulate Trump on his win. No wonder they lost.

Similar with our 991.2 turbo s. Aftermarket sports exhaust since virtually new and no issues with warranty and extended warranty claims inc a couple of turbos. The warranty extended since new over the phone so no inspection. Also have BBS F1 wheels on from time to time. No issues at all its very OPC dependent. Europipe 50 cel sports exhaust does look exactly like the stock exhaust other than the 76mm pipes.

many thanks for all comments, it sounds phenomenal with the akro but i think I might bail and go for a standard car with a porsche warranty or one that can be transferred and play it safe. I enquired with warrantywise and their quote was three times the Porsche one and I had to set limits for labour rates etc so not too confident with them but they have good reviews, does anyone have any experience on claims with them
