Review: CPI Inframe Pipes in stock a banshee

Looks:

The pipes look awesome, the chrome is very good, can say great, not excellent. They look great off the banshee and beautiful on it. The silencers, in my opinion, are the best looking. In a scale of 1 to 10 I will have to give a 7 for looks.

 

 

Construction:

The pipes are very well constructed, but I have seen better construction detail from other brands, specially on the welds and match of pipes. The left stinger tube has more welds than the right one. For some reason they did not bent the tube. Also, the divergent cone in the left pipe is angled more to the left while the right pipe is angled more down. Whent the pipes are mounted you can see that they are not exact becasuse of the divergent cone. Probably this was done for clearence. I will have to give it a score of 5 out of 10 for construction.

 

Fit and installation:

I took the whole front fender out to make installation easier. After that I just removed the stock exhaust system. You need to take the O-rings from the stock pipes since the CPI"s do not come with does installed. Also, you need to buy a pair of bolts to secure the pipes to the pipe hangers. I used stainless steel bolts.

Installation was very simple, no problems with clearence what so ever. You can secure the silencers with the stock bolts.

Finally, you need to trim a little the fender. I did it with a grinder, very easy, just need patience.

 

So for fit and installation I give it a score of 7 out of 10.

 

Sound:

All I can say is that this pipes are loud. Probably louder than any other brand pout there.

The sound is okay, you just need to adapt to it. So I give sound a score of 3 out of 10.

 

Performance

My banshee was jetted with 280 mains, needle in stock 3rd position, pilots 25, air screws 1 1/2 turn out from seated, airbox lid off, everything else stock. With stock pipes this jetting was great. With the CPI's the power gains were clearly evident. Mid to top end power was greatly improved. I felt I could get more out of this pipes so I put on 300 mains. Run okay, but had to lower the needle to the 2nd notch, leaning the mixture. Now the hit was more power full and it kept pulling on top. Also I had to turn in the air screws, 1/2 a turn from seated. Probably I may need to go with a bigger pilot jet.

 

I still need to set the jetting to be almost perfect, but right know it runs like a charme. So this is what I say to CPI :notworthy: WOW!!!

 

Bottom end power is almost identical to stock, Mid to Top is wayyyyyy better. So in the power deparment I give CPI an 8 out of 10 for a stock banshee.

 

Conclusion:

There are many good pipes for the banshee. Some pipes are suited for bottom end power, others for mid, others for top, some for stock engines, some for ported. I can say this, if CPI's work for a stock shee... imaging what they can do with mods :whoa: . This is really an all around pipe. For recreational trail riding, or drag racing, this pipes are great. For competing in CrossCountry or any other type of race where power is need in the lower rpm range, then this is not the pipe for you. There are better pipes for lower end power. Mid to top end power has a name and it is CPI. I do recommend this pipes. :D

 

 

Any jetting suggestions will be greatly apreciated. My shee is basically stock, except for the pipes and airbox lid removed. I ride mostly 1000 feet from sea level and higher, probably up to 3,000 feet. Temp around here is 70-85 farenheight. My jetting right know is 300 mains, needle in 2nd notch, 25 pilot jets, airscrews 1/2 turn out from seated. Want to know if you guys with CPI's and similar mods and conditions have similar jetting.

I have to second what Stephen said. People need to take note and write reviews like that. I myself try to cover all area's when doing a review such as this. I give you a 10/10 on the review. :clap::headbang::clap::cheers:
