Has anyone ever had their warranty voided because of these two mods added to their ride? just asking. Thanks for the feed back fellas

 

If you need to do some dealership warranty work a lot of people go in stock. They might blame your mods for problems even if it's a total lie. Although exhaust should be fine as long as it's a cat back.

 

If he is doing just a cat back, yea you could swap back before going to the dealer.
The op mentioned headers, that is a major job & is not an easy swap.
You need a lift & I'd say at least 6-8 hrs, there is no short cut doing headers on the g.
No room, could barley fit my hand between steering knuckle & bottom of header on d/s.

 

Dealerships will look for the lamest excuse to void your warranty. A catback is less involving in terms of install and risk factor. Headers bolt to the Engine Head directly meaning the dealer will have a much better case to screw you if something was to go wrong with the engine.

If the dealership is mod friendly and are willing to install them for you, that's a different story. I'm sure their labor charges will leave a hole in your wallet though.

Off topic: Headers are a waste of money and not worth the ROI (parts and laborwise) in my honest opinion. A catback and some resonated test pipes is as far as I'd go.

 

Sam, headers are not a waste of money. That's just your opinion, you seem to have long tube headers before your motor swap.
Are there other mods that can be done for less of course.
The factory headers flow like crap, have you seen the inside of the stock header.?
Plus with the aftermarket header, you can use a dremel to smooth out any rough spots.
Wish I took pictures of the inside of the stock header. It's made like crap.
Bottom end much more responsive & top end was day & night.

I stand corrected, unless they are Fast Intention long tube headers they don't work.

 

Thanks for the response fellas, I have an extended warranty on my m37 and was wondering about getting these mods done, I would be getting the cat back from stillen and some headers along with high flow cats and a air filter kit and last but not least a tune. Just trying to gather all the information and take it from there. I know the stock headers are very restrictive along with the factory exhaust, just trying to free up as much horsepower as I can. If you have anymore ideas please share them.

 

Explain to me how a $2000 investment, 1 day downtime and warranty voidance risk for a few horses gained over test pipes is worth it

 

Thanks for the info G37Sam and RISKY GUY, I do want some added power but not at the cost of losing my warranty. The cat back and air filter kit is probably what I will stick with. This is what forum talk is about, giving good advice and pointing people in the right direction so they can make the best choice for them.

 

Hey fellas, I was able to find my extended warranty coverage and kind of confused. I don't see anything pertaining to aftermarket exhaust and headers and so forth or unless I'm reading this wrong, best guess, is that I will just have to call to get a better understanding. I wanna do the mods but not gonna risk the warranty as stated earlier, let me know what you all think, thanks fellas

well, just got finished speaking with a person from my extended warranty company and she informed me of headers, removing emissions controls items i.e. cat converter and over sized tires and some other minor items would void my warranty. So I guess I will be doing the exhaust and air filter kit

 

That's because you bought long tune headers.

Got shorty headers from stillen $550
Had my shop port & open them up even better $100
Labor for install $400. & a day.

That's less than I paid for just my fi cat back with HFCs.
Btw that was 10-20whp max for 1600 plus labor.

 

You did Risky Guy, I know you was happy with that price!!!!
