SuzukiSavage.com - Best performance muffler

russ_g Ex Member	Best performance muffler 05/12/05 at 14:12:24 Ok i'm not big on sound (although i don't want something that will tick the neighbors so i'd like to avoid too loud) - but a little more power interests me. In conjunction with a "stock" k&n (meaning a straight swap for the factory filter), what would be my best bet. An of course jetting to go along with that

Stock Harley Davidson Sportster muffler works great , sounds more rumbly (lower tone), and ain't too loud. Chrome is outstanding. I accessed the factory-sealed mixture screw, halved the white needle spacer thickness, and jetted up to 155 main about the same time, but it's still just a hair lean at wide open throttle. You can see what it looks like in my Tech Section post:

I got a good power boost from this combination.

I'd like to try a 160 jet, open up the air intake, and I have an aftermarket carb as well (Thanks, Lancer) so who knows where I will wind up with this thing.

That is pretty much the same setup I'm using on my '02 except for the main jet which is a 152.5. To help with the air flow to the carb I went wild with a 1/4" drill on the air box door, must of drilled 60 holes in it till I ran out of beer, oops I mean room. So far I'm very happy with the results of both the beer and the modifications Grin

Drilling out the airbox door seemed to help with the top end a little, maybe and extra 50-100 rpms. I tried it without the door for a month but got a bit nervous that mice would move into the airbox when I was not looking. The only difference between the drilled door and no door was more intake noise without the door, the change in performance felt the same.

I yanked the door, and got leaner at the top end so it must have done something to increase the airflow. Tight now if I run wide open for a few miles, the pipe will put out pretty consistent flames when I stop - like at a red light on the access road after going wide open on the highway.

I thought I was too rich at WOT, but removing the airbox lid made it worse so I think I'm still too lean.

Just for grins I removed the stock air filter as well - It got really bad then - backfiring and alot of slow-burning fire from the pipe. Looked like the old cars with the flaming tailpipe mod.

Of course it's at night when I'm doing this - no fun in the daytime. The children in the SUVs that pull up by me really dig it. A few hot moms, too.

May have to put on a small acetylene bottle with a nitrous switch and spark plug so I can do it on demand. The rear brake lever might complain. BUT IT LOOKS SO COOL.

Don't want to fix it broke so I'm leaving it alone right now.
