I've been trying to figure out what exhaust to put on for weeks, and i'm no closer now then when i started... I like the titanium 4, but not impressed that they have no header pipes for it, that and i heard they rattle apart, also has anybody seen or heard about the looney tuned pipes?? Anybody and everybody give me input on what you have and if you like it or not.. thanks p2b

 

Just depends on where and what kind of riding you plan on doing with a particular pipe?

 

Read this, its a good place to start:

I have the LTE's on my YFZ. they preform great,look great, but I dont think they are worth the extra bucks. I would consider the new endcap with the disk spark arester if it were me. no more big bucks for exhuast systems for me. not worth it IMO.

 

I agree. The inexpensive HMF slip on on my DS has worked great for me. Its performance is night and day better than stock, quality is great, and it comes with a spark arrestor that is legal in sanctioned racing events.

 

A friend of mine put an HMF on his machine last month. There is a noticeable power and delivery improvement and the noise in not unbearable. Nice unit IMO.

 

big gun race its loud but a lot of power

 

You really can't get much better than the Stock header pipe on the DS for all around performance. I purchased a Ron Wood Pipe right after bought my DS. To be perfectly honest this pipe is great if all you do is Drag Race! I have restored my original header pipe and added a HMF Slip-On - performs great for all types of Riding.

 

has HMF actually posted HP numbers of thier slip on over stock?

 

Not that I am aware of... However, Mr. HP has all of the actual Dyno test results and comparisons including the results for the HMF Pipe.
