How hard or easy to core exhaust?

[joon82]

Just got dremel last week so plan to do some DIY.
How hard or easy to core exhaust?
I have picture with description but need to know input from people who've done it before.
So is 3-5 hr work worth it?(guessing 3-5 hr)
Any tips to cut the welded tip?


So far I did home powder coat spring,cap,and plate.
Also made shape out of stock cover.
It looks really good from distance but don't like it from close. My first metal/aluminum work.

 There is a tread in the tutorials some where. I tried to do my stock pipes and gave up shortly after starting. I did however shorten my SilMotos, and that was not too bad. My guess is that your 3 to 5 hours will probably end up like 6 to 10.

There's two tutorials I found:

I partially cored / chopped my stock cans. For those, you definately need more then a dremel.

Many say an angle grinder, I used a miter saw with a large abrasive wheel. My cuts didn't like up exactly since I sort of winged it.

The hardest part was grinding down the tack welds to pop the caps off, and then hammering them out.

I followed the tutorials that I found on the forum and they were all that I needed.

OP I just did this and used booger's tutorial. It will definitely be more than 5 hours. Cutting apart both exhausts probably took 5 hours alone in time. You will need more than a dremel. The angle grinder is crucial. But note that even the 4 1/2 cutting wheel was having trouble reaching the inner baffle to cut at once side is deeper than the other inside the steel casing. I ended up just trying to make a whole diameter cut before I couldn't reach anymore of the metal and just bent it back and worth until it broke since steel is brittle.

Oh, and definitely wear safety goggles, gloves, and a mask.

For me the hardest part was drilling out the riveting holes. That inner steel tip is a pregnant dog to get through.

bet that full Arrow exhaust is looking pretty good right now

didn't take me 5 hours to cut them up, maybe 2 but definitely not 5

Haha oh yeah there were a few times I was just like @#$%. My rivet holes aren't as straight and beautiful as yours =(

BUT I installed it this afternoon. OMG the sound is intoxicating. All those hours of blood, sweat and a good bit of cursing I will say was well well worth it.
