Today's lesson in Ballin' on a Budget is brought to you by Nasty.
I figured what the hell lets see what I can do with these buttfugging ugly quiet as a mouse stock cannons. Here are the results. It is not perfect by any means, it's more or less just a prototype for fun only using scrap I had lying around. Ballin' on a Budget!
The first thing I did was chop 8 inches off the stocker, not even half length.
BTW I do not recommend cutting off any more than 8 inches!
The result of that gave me somewhat of a cool, but crude, Mad Max look. Not bad, but not pretty either. I road around for a couple days that way and it was loud as fuck! Too loud and boarder lined with sounding shitty too. Butt dyno told me I lost some ponies in the midrange.(I know butt dyno don't mean shit) Basically I might as well have cut off the whole muffler and ran myself a straight pipe is what I was accomplishing.
Something needed to be done besides beautifying the end. I needed to build a plate at the end to baffle some of the sound and give it some more back pressure. So I started dreaming up some ideas until I had something I thought would work using a cardboard mockup and some scrap muffler pipe I had lying around.
With my cardboard cut out and my muffler pipe cut and expanded to fit the already existing main exhaust tube I found some scrap plate steel(1/4in) to use for my end plate, and cut it out with the plasma torch.
After much grinding to smooth edges out and to get everybody fitted together I welded some tabs to the plate in strategic locations... I fitted my muffler pipes in place and mounted the back plate over them and used self tapping screws to hold it all in place(everybody was sealed with copper sillycone later on after everything was modified and fitted)
Next was to modify the the original end caps to make them fit. First I had to slightly enlarge the main hole to make the 2in exhaust pipe fit through after that I needed to cut a notch to fit around one of my strategically placed brackets. It's not perfect but gets the job done none the less.
Job well done if I say so myself. Looks just like stock but shorter and lighter!
Before
After
The volume is a lot louder than stock. I would say when it was first cut and ran open its volume level would rank up there with some of the loudest slipons. Now after my modifications I would have to say the level is somewhere between a yoshi with a baffle and one without the baffle. As for sound I'd have to say it sounds just like stock but much louder. Kinda like some old fucking Volkswagen at idle. She does sound nice and healthy at higher rpm under load. Now my butt dyno(I know butt dyno don't mean shit) tells me there is no obvious loss/gain in power over the original stock cans, but the midrange does feel noticeably stronger than when it was just cut and open. One fact I can pass on is while cruising this afternoon, at normal highway cruising speeds(not speeding retardedly) I noticed a 3-5 mpg gain in economy.
