There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (blueing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing. See the CHEMS/LUBES section for products that will help prevent or remove blueing.

Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that may need to be made during. or after, installing their product. If a jet kit or fuel processor is recommended, see the FUEL/INTAKE section

COBRA 6855 5 Stars all the way
Once again my experience with DENNIS KIRK went great. From order to delivery, as advertised and without a problem. I installed this COBRA exhaust system on my 03 FXDWG, a perfect fit, the chrome finish is flawless and brilliant. The billet tips are a perfect ending for these pipes. The installation is very easy, all the parts are there and go together quite well. The sound is beautimus, the tone is great, not too loud but loud enough. If you are looking for an exhaust system and a place to get it....DENNIS KIRK.....COBRA..... Works for me.

Awsome sound and looks
These pipes with the black cover look awsome on my sporty nightster. The sound is great no more loud noizes in my ear all the time but still a nice low rumble.

Nice pipes...
The fit and finish is exellent. The fit on my Softail Custom (FXSTC) was bolt on, no problem...

These are loud though, so I plan on a ticket or two...

They also sound nicer to my ear than vances which sound too caverny for my taste. I am still playing with my tuning (I have a ThunderMax installed) but the bike is more responsive with those pipes, especially at low rpm...

I am also pleased with Dennis Kirk's service, this was a painless purchase, will do business with them again...

Excellent Exhaust
I installed the exhaust on my Fat Bob and boy did it make the bike look so much better, the performance was noticable and the sound was perfect, got so many compliments on how good it sounds. It gets alittle tight around the oil dipstick cap but you can still remove it.

great pipes
I got this set of pipes about 7 mouths ago for my 2006 Dyna Street Bob. I had the 95in cylinders , 203 Screaim Eagle cams and Screamin Eagle Heads put on it. With this set up it did 101hp and 113 fpt. So the pipes are good.
