    Remove exhaust tips?

    Has anyone removed the original exhaust tips?

    I am annoyed by the visible air gap between the exhaust tips and the muffler outlet pipes and was looking to replace them with a nicer aftermarket set of chrome tips. (Yes, I'm easily annoyed. Aren't you glad you're not my spouse? )

    Re: Remove exhaust tips?

    Nope ... haven't thought about removing them. I keep them polished up real nice.

    I kinda figured that the air gap was to let a little cool air in to mix with the hot exhaust gases to prolong the life of the tips and so that they would not get discolored by the exhaust heat.

    All of my motorcycles always discolored the chrome exhaust pipes REAL QUICK.

    Had put a pretty set of chrome headers on a 454 years ago. They were discolored in a week, then they didn't look so pretty.

    Re: Remove exhaust tips?

    My experience has been that with modern vehicles, the exhaust temperature is very cool. The many catalysts absorb whatever heat remains in the exhaust gas. Thus, I have never had problems with any discoloration of exhaust tips - chrome, stainless or otherwise. I can understand why headers would become discolored (close to engine) or why motorcycle exhausts would get discolored (no catalyst to absorb heat), but modern car tailpipe temperatures are very cool.

    I see no reason for the gap other than cost-savings, hence my annoyance. Hey, at least it's better than mid-1990's Pontiacs. Anyone remember those horrible exhaust "tips"?

    The quad tips have been that way for a very long time on the Caddys, including my 01 SLS and even earlier Sevilles and Eldos. It bothered me at first too, so I know what you are talking about with respect to the gap. However, they are quality tips that still look brand new, so I am ok with them now.

    Maybe the air gap is there to protect the nearby plastic (or whatever you want to call it) bumper? My '97 ETC has aluminum heat shields directly above the tips, in addition to the air gap, so that makes me think heat is an issue.

    modern car tailpipe temperatures are very cool.
    Hold your hand by the exhaust tips after the engine is warmed up and have someone rev it a few times.

    it is HOT.

    Re: Remove exhaust tips?

    Since the catalyst burns the excessive hydrocarbons--I remember the early warnings about parking your car over high grass with the motor running for fear of igniting the grass--I would think if anything, the exhaust would be hotter in today's cars. I vote for the air space being there to dilute the hot exhaust coming out the tip.

    I don't buy that at all, least of all because you don't see these kind of gaps in a BMW or Mercedes. It is not as though the Northstar is a special engine that burns extra hot compared to the competition. This is a cost cut measure plain and simple.

    There are plenty of production vehicles with real stainless piping and stainless outlets (not a pretty tip welded onto a cheap pipe). There is not the slightest hint of excessive temperature (melted plastic of discolored stainless steel). Heck look at a Ferrari - now those engines run hot! You won't see chrome tips with gaps on those exhausts.

    If you can hold your hand up to the exhaust and not burn yourself in 1 second, the exhaust is not hot enough to discolor stainless steel.

    Back to topic: it sounds like no one has tried removing the stock exhaust tips?

    Any update on changing the exhaust tips? I'm looking to do the same and wouldn't mind some extra insight (i.e. is it an easy DIY or does it require welding? what size fits? etc.)

    I plan on doing it when I get back from my deployment. I've seen the new escalade's and I like the look of the pipes against the bumper. But I can't help but think there is some technology that prevents the bumper from melting AND getting all that exhaust to stain the bumper. I plan letting a professional look at it and give it a shot.

    Just use a double wall tip (like the originals). They don't get anywhere near hot enough to damage the bumper or paint.

    Realize how hot the paint gets on a hot, sunny day...

    FWIW, when you see an (OEM) tail pipe RIGHT up against, or built into the bumper, that doesn't move at all, it's a faux tip, attached to the bumper. The actual tail pipe "floats" behind it.

    I have to respectfully disagree with your comments RE Gaps, and premium vehicles. Today I walked up behind a Bentley Continental GT. The Oval tip, beautiful as though they may be, infact have large Air Gaps , similar to The DTS. You can see the road by looking just a few inches inward from the end of the tip.



    Now I am not comparing the DTS to a Bentley, but the Quality appears similar if you are standing 10 feet away.

    You'll never see (real) tail pipes, that are right up against the body. Mufflers move, there needs to be a gap.

    Get a corsa exhaust. Those quad 3.5 inch double wall cannon tips fill the bumper perfectly.
