Cat delete causing headaches?

Gjm127 · 06-04-2012, 10:23 PM

Hey guys,

I got my secondary cats deleted today from my previously installed PE + custom dual exhaust. The replacement pipes are not in titanium.
Sound is about 30% louder, I recommend it to anyone that just wants a louder sound from their PE. Go for it!

One question though, I got a headache about 30 minutes after driving with the delete. I'm a little better now, but is it possible that now that I don't have my secondary cats, it causes me health problems such as headaches, etc...?

Also I park in my garage... I heard getting a cat delete and parking inside is no good either... True or false?

Parking inside with engine running with or without cats is a good way to die. Could be some fumes, but highly unlikely.

Secondary cats don't do much.

cat delete = more fumes, more fumes = more headaches for some.

not sure why you got a headache during driving since youre moving maybe just a bad day? But the fumes may have something to do with it when youre in the garage?

I Have secondary cats deleted. Haven't had any problems from day one. No Heath issues or anything. I did notice alittle more smell of gas or exhaust which might be what is giving you a headache.

I was getting headaches once a week with a secondary delete. I think it was the drone and loud obnoxious sound though. Haven't had one last week.

I am thinking to do the same set up as yours. But I might go quad. Can u do a video of it? I wanna know how the cat delete is going to increase the sounds. Will it be unbearable in the cabin? Any drone ? Thanks

There is a little more drone when I'm on the 1st Gear at a full stop but it seems to go when I put it on N.
As for results, I'll post a sound clip tomorrow. It's simply louder... What's nice is that you get a cold start every time you start the engine!

You can ask me and mapleridge, if you go quad with a vendor in Cali "Detail Addict" for a custom quad you will know loud.

This is my set up with with their pipes and eisenmann race muffler.
