We’re making the tail pipe at sonic speed (*’\u25bd’)<\/h2>\n\n\n\n

It works really well with the stock exhaust pipe from a ZRX1200 Daeg.
It’s 50.8 diameter and… angled insertion with band clamp.
Much appreciated\uff5e<\/p>\n\n\n\n\n\n\n\n

We’re flaring out the collector side ( *\u00b4\u8278\uff40)<\/h2>\n\n\n\n

I’m a bit fuzzy on the details, but… it was 54 mm diameter.
We’re expanding from 50.8 to 54 mm\uff5e<\/p>\n\n\n\n

With the right tools, it expands in a flash.<\/h2>\n\n\n\n

It really is all about the tools\uff5e I’m feeling it deeply\uff5e<\/p>\n\n\n\n

After getting it sharpened, the metal saw cuts smoothly and quietly\u266a<\/h2>\n\n\n\n

You can’t skimp on cutting and grinding tools…
You have to replace them frequently or they’ll burn out, get loud, and it’s the worst.<\/p>\n\n\n\n

I cut out about five shrimp-shaped connectors<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Since I’m rotating it by hand, the welding is all over the place.<\/h2>\n\n\n\n

Every time I think I should do it properly, I should do it properly, but since I only do my own work, it’s inevitable…
It’s a tool I want to get organized when I have time.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Flared out nicely and it looks just right\u266a<\/h2>\n\n\n\n

This time we’re going with the easiest option: expanding the 50.8.
Or we could use 60.5 and tighten the front-to-back insertion, but that’s too much work, so 50.8 it is.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I also made a stopper for the insertion (*\u00b4\u0437`)<\/h2>\n\n\n\n

The Amazon welding sensor boss is excellent<\/h2>\n\n\n\n

R-processed O2 sensor adapter M18\u00d7P1.5 air-fuel ratio meter A\/F meter stainless steel welding boss (R-processed boss_individual package)<\/a><\/p>\n\n\n\n

It’s faster to just buy it. Ends up being cheaper…<\/p>And the weldability is excellent too.\n\n\n\n

\"\"<\/figure>\n\n\n\n

We don’t have time to take it easy, so we’re going at sonic speed.<\/h2>\n\n\n\n

In the end, we spent about three hours on it…
By the way, we don’t do this kind of work as a service, so please note.<\/p>\n\n\n\n

We haven’t measured it, but it’s considerably lighter (*’\u25bd’)<\/h2>\n\n\n\n

We’re doing something completely unglamorous.
It doesn’t appeal to the general public…as always.<\/p>\n\n\n\n

Slip-on installation = anyone can install the stock version<\/h2>\n\n\n\n

We’re even thinking about selling it when we don’t need it & we can always go back to stock\u2014a brilliant idea?
When you get old, your bag of tricks grows\uff5e<\/p>\n\n\n\n

You can kind of enjoy the sound quality on Instagram\u266a<\/a>\u2190(*’\u25bd’)<\/h2>\n","protected":false},"excerpt":{"rendered":"
