Will Cobra tips fit in truck stacks 4" OD ?

[rockbobmel]

I tried to get the specs on these but nadda. Cobra doesn't even have it. The stacks are 3 7/8 ID approx.

I tried looking for him...   No luck.

Look him up in the members list or go over to the fla board. He did away with his website.

Again,No success in photos.

The link you posted for the cobra tips shows them at $47.66 each or $95.32 for the pair. that's more than a pair of Grumpy's tips, and his fit the truck stacks perfectly. IMO

Here's a pic of mine I got a few years ago, and I just ordered another set for a another truck stack mod I'm doing.

Those are real nice.  I like the "bolt pattern" !!

I shopped around and got mine for $81./pair. at PDI Racing.

I don't know about these.  They aren't going into the ends without either grinding the inside of the pipes or the OD of the tips' flange, or maybe a pipe expander. I may have to send them back.

[rockbobmel]

Some progress. What a PITA!

[Bighead]

Grumpys will install in about two minutes and fit perfect. And are milled from a solid block of Aluminium. Cant say enough about the quality of his tips

[rockbobmel]

I know. In hindsight, I should have got Grumpys. I tried to post pics but again, I failed.  I have the pipes ID ground about 2/3 (tips inserted) and my dremel burnt out.  I am gonna get a cheapo wallyworld rotary tool to finish it.  
I bought a set of cobalt drills but that chrome is hard!! I don't want to remove the pipes and may have to grind a spot to get the drill to bite.  I even thought of just pressing them in but I want the option to add silencers if the tips don't quiet it down.

[Bighead]

Grinding away the chrome and they will rust in that area....

[rockbobmel]

Finally gottem in............ Whew, What a PITA!



Almost as hard as posting a pic..........

Not many do. He's been talking about "hitting the pipe" a lot lately though. (I think he confused you with a pic that rockbobmel posted)

[rockbobmel]

I just listened and noticed that because it was in an enclosed area behind a stored car, the sound was somewhat boomy and not that clear.  I'll do it again when it comes out.

[rockbobmel]

Pics Finally.

dude, those look awesome. In hindsight was the fabbing worth it? Love to do that at some point.

I was going to get Grumpys tips but I had a hard time finding him so I jumped on these.  I was grinding in a badly lighted area in the cold that made it painful. I just committed to fitting them and wished I had been more patient.  I was originally believed that they would fit right into the stacks without mods. I think Grumpys do. The chrome matches nicely though. 

[Grumpy]

Mine do  fit the pipes plus no need to drill holes in the stacks. I could probably duplicate them with out any problems.

Hey Grumpy, if you can duplicate this style of chrome tips that would be ready-fit, I'd have interest..? Wonder what that would cost?

i will check, normally I buy 1 in wall tube to cut them from, those would need bar stock, that would be about the only change in cost.

Hey Grumpy! Mounting Mark's silencers in my 4" truck stacks today. Would love to mount these a little farther in so I could fitup some of your nice chrome tips...
