Has anyone ever used Looney Tuned Exhuast on any kinda atv if so were you very impressed by it becuase I am looking into purchasing a setup for a 660r and a 700r. My wife doesn't think I need to be modifing mine unless I am willing to modify hers at the same time.
I know that LTE claims to give the 660r a mid gain of 13.5hp and a top gain of 10hp but it doesn't say what it does for the 700r, if anyone knows or can help me find out anything please tell me thanks.
I beleive that the 660r has a rated hp of 36 max and if thats the case then LTE is giving it a 38%hp gain in midrange and a 28% increase in top end that is outragouse. I would really like to see gains like that on the 700r. If anyone can help please tell something.

 

i dont know if it give you that much gain. i would get it just because it looks the best. i dont know if it will perform as well as some others though. it is also quite expensive.

 

ONe of the best exhaust I've ever used.....You can feel the power and it increases HP.

 

idk about that exhaust, but hey the e2 slip on with a powerbomb header works really really well.. like 3 of my friends have raptors and im the fastest, this one kid just has an air filter and i beat him, one kid is stock i beat him by a lot, and one kid has just lower gearing and depending on how im driving sometimes i take him in accel and top speed, but most of the time he beats me in acceleration because of his gearing. But umm wait what are we talking about ??? [img]i/expressions/face-icon-small-smile.gif[/img]

 

I netted a 12.44 HP gain over stock with the combination of GYT-R Filter LTE dual exhaust and a PCIII with a custom dyno tuned map. The dyno where mine was done shows the 700R produces 38 RWHP stock and after mods and tuning 50.44 RWHP with a broad flat torque curve. You will see even bigger gains against single exhaust systems if internal mods are done.

I love my LTE's on my 700R great low end, killer mid range and good top end power [img]i/expressions/face-icon-small-cool.gif[/img]

 

I looked at the LTE system for my raptor and I decided against it due to price($740), the fact that its twice as heavy, and third yamaha did not design the bike to have the heat/ muffler on the left side. I think its CT full systems that made the most hp on the 660R (46-47). I went with the Trinity Stage IV and have liked it very well. $500 and produces 45-46 hp (Not extra, total) Especially if you have to buy 2 systems the $240 difference is a good hunk of change saved. On the other hand, the LTE looks awesome, sounds great, If I wasnt such a cheap skate Id probably have one on my own bike.

 

Believe it or not, the LTE's put less heat on my leg than the stock exhaust. My buddy rode for two days at the dunes with shorts on and never once burnt his legs.

The LTE's can be had for 699.00 delivered, yes a little more money but well worth it in my opinion, also the LTE's duals are still 5 lbs lighter over all than the stock exhaust[img]i/expressions/face-icon-small-cool.gif[/img]

 

Pardon my ignorance, but I believe that Looney duals can be bought with ceramic coating.

What is the ceramic for? Is it just for looks? What does it look like, compared to the regular one?

Thanks!

 

Keeps heat in, protects the stainless etc., etc. Not trying to be a nutswinger about the LTE's but they really are great pipes in comparison to all the singles IMHO. You gotta remember that 2-3rwhp OVER another bike equals a decent beating in most cases assuming the riders are equal. Well worth the money IMO. I've seen graphs that are a 52-53rwhp for 700's with just the LTE's, commander and intake. That's pretty serious power for the money!
