My friend is looking at getting a new exhaust for his 400ex with a K&N air filter and stage 3 dyno jet kit. He has narrowed it down to a Pro Circuit T-4, White Brothers R4, FMF Titanium 4 or the Yoshimura Stainless Steel Comp Series. Is there much difference between the Yoshi comp Series and the TRS Titanium Pro series? Should he get a head pipe or just a slip-on? Which one would give him the best power and suond (not neccessary the loudest)?
Thanks

 

should should also look at hmf they are really good pipes if you go to there website you see that the top hp is 6 and the toptorque is 9 thats pretty good or a slip on and you can get them any many different colors. the website is www.hmfengineering.com

 

tell him to get a curtis sparks they are the best! mine is absolutely awsome gobs of tourque and an amazing mid range and a great top end. the site is www.sparksracing.com check it out you wont be dissapointend.

 

my # 1 vote goes to curtis sparks also. i also wouldn't mind having LRD, CT, Duncan, or HMF etc. for the most power, i would look into engine builders pipes. a complete system will always give more power than a slip on. with some of these good pipes you can't even buy a slip on. they just come in complete systems.

 

how loud is curtias sparks pipes?

 

i would say sparks, or FmF ti-4. if he isnt thinking of doing any major engine mods in the future he should get the slip-on. if you are considering slip ons take a look at the HMF great pipe and a lot less $ than a full titanium system.

 

dont u think that the sparks pipes are kinda expensive?(489 for exhaust)

 

speed cost money
