If i get a a titanium 4 muffler for a stock 400ex, should I get the hi-flo, powerbomb, or the stainless tI4 mid pipe. I ride mostly trails and some tracks evey now and then. Does anyone have anything good or bad to say about the titanium 4?

 

i dont think you need one yet, maby after some airfilter mods and some engine. right now a slip on is perfect.

 

If I get a K&N or a UNI, what else will I need to do to the engine before I need the midpipe? Which would u suggest? I have heard some people say just grind out the welds on the stock head pipe. Do they mean the welds on the inside?

 

yes but you will see very little gains from it. I ground them out and could not tell the difference.

 

Do u have any suggestions on which mid-pipe to get?

 

I have heard alot of good things about the powerbomb. thats what I'm going to put on mine [img]i/expressions/face-icon-small-wink.gif[/img]

 

I have the PowerBomb and Ti-4 on the Z400. It is a WICKED pipe, but very loud without the quiet core. On the 400EX I have the PowerBomb and PowerCore4. (Plus vented airbox lids and K&N's with Outerwears on both bikes.) Big power increases on both machines!!!

The PowerBomb is worth getting. For the extra money, it isn't worth getting the Titanium mid pipe. It saves a little weight, but I went with the stainless mid pipe because it is cheaper. The Ti-4 is a great muffler, but like I said, it is loud!

 

I have one and I think I liked my power core 4 better. The power core 4 was on a 2001.
I have the FMF Ti- 4 on this 2004 w/ ss mid pipe and its loud not real loud but loud. I liked the powercore 4 because it was a complete set up ie: spark arrester + no water would get down in it because of the shape of the outlet.
