Default ebay x-pipe... worth messing with?

Just curious if anyone has installed one of those x-pipes from ebay that you have to weld in (the ones that are just the "x")?



Also, what size are the stock pipes on a 02 Coupe? 2.5"? 3.0"?

What are you expecting from this? Are looking to change the sound or improve performance? If sound, this may help some. If performance, I wouldn't hold my breath.

Sound is a major reason for this... I just put a SLP Loudmouth exhaust on and I not really liking the "motorboat" sound I am getting as well as the popping. I am hoping that putting an x-pipe on will get rid of these sounds (or at least reduce them).

Is there a performance issue with using something like this? Are the tight bends something that will reduce the current power? Or will I just not get any gains from this? I wouldn't expect much of a gain no matter what pipe I go with. Am I wrong in that assumption?

The X pipe design will have an impact on the performance gain/loss. By the provided photo the design of the one shown looks less than optimum to me, but I could be wrong. I'm basing this on visual comparisons to known good designs. By the photo it looks like the center area is too squared off, more like an H pipe shape than a smooth flowing X pipe. If the price is right it might be fun to try none the less.

Were you planning to tig or mig weld it?

You can buy the C5 X pipe in the used parts section all the time. For the cost it's not worth the trouble to make one. The MagnaFlow X pipe is all stainless too.

Really! Sure looks different to me.

Looks closer to the Bassani type which I have. If you have access to all that is needed for the swap, I'd say to go for it. It should help with the motorboat sound...

I have a borla x-pipe I'll sell ya for $75. All you have to do is cut off a section of your mid pipe and these clamp right on, and have the flange for the cat back. Basically your removing the H-pipe section and replacing it with the x-pipe.



Pipe does have a small dent in it.

I was thinking the same thing... that's why I was asking if anyone had put one on and had any luck with them. It's hard to tell what is going on inside that thing.

Just MHO- If you have the factory H-Pipe and its sound you want, Keep it !!

I swapped the H-Pipe for a Magnaflow X Pipe 2 years ago and while it eliminated the rattle noise it also subdued the exhaust. This to the point that I was forced to install Corsa Extremes

In hindsight, I think I should have lived with the annoying rattle in exchange for very raucous bodacious exhaust sounds on my 02 Z06.

Another more practical thought is this- if you EVER intend to install LT Headers they come with an X-pipe section.

I don't think I have to worry too much about losing any sound. The SLP Loudmouth exhaust that I have is just straight pipes so it's REALLY loud already. If it quieted down some I wouldn't mind, but I doubt it would quiet too much.

I do know that LT headers come with an x-pipe, but I don't see those in my future anytime soon. That is why I am trying to go with a cheap $30 x-pipe rather than the $300 ones like the Corsa or Borlas.

That is a Magnaflow universal X pipe It is totally hollow on the inside between the in and out pipes, so there is no restriction. You can pick them up at Jegs or Summit for about $50.

Where have you seen the "universal x pipe" by Magaflow that looks like the original posted picture?

This is a Magnaflow, it doesn't look anything like the one OP.

Thats what I get for trusting my muffler guy I guess, then again the one that I saw was 3 years ago and its on my truck not my Vette so it's not like it matters I guess. Anyway it is totally hollow in the middle.

Hi I'm new here to the corvetteforum and thank you so much everyone, I've learned so much since I've signed up! I know this is an old forum and post, but I figured since I had this done to my car, I'll let you guys know how it sounds. I have a corsa sport dual tip exhaust with the universal x pipe welded on. Here's a link so you guys can hear how it sounds, let me know how u like it or hate.
