Default Open Headers C5

I have been thinking of running open headers on my 98 C5. Besides the noise and cops I guess.. any other issues I should look at coming upon? Also tools needed to do the work? Thanks!

That sounds like a horrible idea. You'll either go deaf or asphyxiate. But try it and let us know which happens first.

Why do you think that? Idk how I would asphyxiate either, but alright. Lmao.. I don't understand why you're against that. Either you're an old bastard or you don't like loud, scary noises. Anyway I will let the forum know how well it turns out (:

The cabin is not hermetically sealed, exhaust gases would enter the cabin and give you a serious headache at the very least. Open headers is not a great idea, you want the exits to atleast be beyond the front seats of the car. If you're dead set on doing it I would recommend running a catless X pipe with turndowns attached to the ends.

I like loud but open header is ridiculous and the drone is unbearable... I had to drive my car for about a week with turndowns after my x-pipe while I was waiting to have my exhaust modified, it sounded good at idle but anything above idle was excruciating and didn't sound good at all

I started mine up with open headers once to see what it sounded like, but wouldn't recommend driving around like that. Put turn downs at the end of X-Pipe for running at the drag strip as dynoed showed gains over TI exhaust (in fact I bolted up a stock catback and lost .3/5mph in the 1/4) and on the drive there I put my helmet on because head was hurting from the resonance, put ear plugs in for the return trip and ears were ringing when I got home. Cruising sucked, but sounds great at idle and WOT though...

Everyone who has ever ran open headers says it's terrible.

Besides noise and pollution - which will be bad enough to **** you off, let alone everyone around you - you're also going to confuse the **** out of your car's electronics, and you may well melt stuff near the header collector.
