Rolled tail pipe tips...

[fastpat]

I'm looking for a source of ready made or custom rolled edge tail pipe tips. Most custom shops simply cut the tail pipes off, either straight or angled, but don't have the capability of forming a first class finished rolled tip similar to the factory tip, only in a larger diameter such as 75 or 84 mm. And, yes, I want it in stainless steel.

This will get you started. Most major muffler manufacturers also have tips (Borla, FlowMaster, etc). Magnaflow have a nice product.

Those are all rolled in the wrong direction, i.e. they're rolled towards the interior of the pipe. I want the external rolled tip, it's much more a finished look in my opinion.

Take a look at a stock tail pipe to see what I mean.

go to a auto parts like pep boys and look for a nice stainless steel tips. In this days I buy one.

[fastpat]

Those stores do not have the type I'm looking for. Here's a few examples.

3 inch x 7.5 inch


3 1/2 inch x 7.5 inch


4 inch x 7.5 inch



These tips are sold in the UK, and it looks like I'll have to order from there since no one in the US makes one. In my opinion, they're a much better looking , traditional tail pipe tip. All in polished stainless.

wow.. this got me thinking.

Quiet Boom does trick machine work. I may have to stop by and visit him in Ohio so I can say hello to my buddy Christian. yep if he can build trick fixtures for drilling broken exhaust studs I figure he has a bright idea on this one.

thx

Exactly. Think about all these guys that have these otherwise really cool single and double outlet mufflers with crude cutoff tail pipes that are literally begging for the elegance of a finished tip.

I'm in motion already. Quiet Boom has been notified.

I want the real deal.. if it's doable?

We shall find out my friend......

I understand its all personal opinion, but I can't see how the "rolled like a shotgun shell" look is better looking or more finished then the other. Oh well.

I think the "shotgun shell" style tips look more period correct on early cars. The more finished options look better on impact bumper cars.

[Nitrometano]

Pelican dont have that pipes? I saw it at Performance Products.

[TWork]

Summit has a whole slew of tailpipes. Not sure if they have exactly what you're looking for, but its worth a try. May also be worth looking at a place like Jegs.

I don't have empirical data to show more power with the "shotgun shell" roll, but the classic rolled tip, like the one that came on the cars through at least 1989, keep the inside diameter all the way to the end, while the inward rolled tips narrow the ID, not much, but why have less diameter at all. Further, the inward roll traps moisture and exhaust byproducts, even stainless steel will corrode eventually. And last, I think the inward roll changes the sound output slightly, to a more nasal tone which I definitely don't like, but that's entirely subjective.

Jegs and Summit do not carry this type of tip.

Nitro is right in that Performance Parts carries. I believe Wayne mentioned that he can get anything they carry.

Wow, your Electrolux has a 3 inch tube? All I can say, is Holy Cow.

I'm at work now guys but I'll look into this later when I get home. I did once make a trick SS tip for an old mustang I had.

[89911]

One of the reason that I like the "wrong way" rolled tip is that the heat is kept isolated from the outer layer, preventing the goldish hue that forms on stainless when it gets hot.

[A Quiet Boom]

OK, Finally home so I can read the whole thread and reply. Typically these tips are sheet metal work and I'm not set up for that, at least not on tubing. Machining a tip out of a solid chuck of stainless doesn't make much sense either but if i could start with heavy way SS tubing this might be of interest to me. The tip I made years ago was a copy of the old Borla tip with a small tube in the center held to the outside pipe by fins, really simple to make but not all that flashy. Ideally a tip would not add any back pressure and might even reduce it if designed properly. One idea of had for a while is a tip with a large center hole surrounded by a bunch of small holes that were somehow set up to increase flow. I'm thinking a venturi type design that might use air passing under the car to siphon of some of the exhaust gas and blow it out the smaller holes. The trouble is none of this in all that easy since there'd have to be dyno tests to prove it works and a ton of R&D for a part that not everyone might like the look of. Let me think on this for awhile, maybe I'll come up with something.

One thing I'd like to do is set up a jig to build my X-pipe mufflers that could replace 2in 2out mufflers. I just love the sound of the setup on my car but it's two large to fit cars with factory bumpers. If I go to smaller pipe and mufflers I could get it to fit but then there is the challenge of getting the right mufflers and doing the whole thing out of stainless, my last estimate was that it would cost me upwards of $500 just for the parts plus my time. That was before I had a CNC that could make the flanges cheaply though.

[fastpat]

I've ordered the rolled tips from the UK, but keep us posted if you come up with something.

Another fabrication approach would be to weld a ring onto the end of the pipe, then grind and polish.
