LRD 400 EX EXHAUST SYSTEM Good or bad? Or should I get sparksracing exaust system?

 

lrd is very loud and makes its power on the bottom,

 

In the pipe shoot out, the SPARKS made the most HP,but the TCRACING pipe made the most HP in the RPM range that you need it.TC--> 814-723-3514

 

What do you think about the FMF pipes ?

 

I don't know any thing about FMF pipes.

 

You should also consider the white brothers e-series. I think it won that shootout, but would have to double check.

 

I personally have FMF on my 300EX and my 250R. I am going to switch to ESR or Sparks on the R, and a Sparks on the EX if i keep it. Go for Sparks! I have heard very good things about the TC System.

 

I am not sold on White bros. pipes, my friend has the full pro meg system on his 300EX and my other friend has a stock 300EX and I had a 250X with a slip on PC pipe. Both the stock EX and my X seemed to have more power through out the entire RPM range. The white bros. pipe just seemed to be pretty loud and not that much power. ALSO he has a K+N filter and it's properly jetted too so I don't know I just don't like white bros. I think the PC pipe is excellent, I know this is for a 400EX but I just thought I would share my experiences.

 

Killer raises a good point. I have also ridden 400s with the Pro-Circuit T4. It would also be an excellent choice IMHO.

 

I have an E-series on my 400EX with 18 discs and a 165 main. In drag races with friends I can beat my friends EX with a Pro Circuit T4 and pull dead even with another friends stock Banshee.
Combo: No airbox lid
165 main jet
42 pilot jet
Needle moved up one position
White Bros. filter
E-series 18 discs
Also it's not anywhere near as loud as the T4 system.
