Questions: I bought exhaust kit # 641856K , do you recommend painting it, I noticed a little rust forming around the crimped ream of the muffler and it has only been about 150 miles on a new build. If so, what type of paint?
Question By: Mike Rabalais on Jan 1 2021 5:49 PM
We never paint them but I suppose you could use some high temp engine paint if you wanted. They are plated.

Questions: I got this system from you only to find that I may need to modify it. There is a Bumper Winch connected to a PTO. The PTO drive runs over the cross member at the same spot that the exhaust pipe is designed to go. What is the appropriate fix? Thank you, Marfk
Question By: Mark on Nov 17 2017 6:53 PM
If you have a PTO then they used a different long pipe to accommodate. You'll have to modify the long pipe if you want to keep the PTO off the back of the transfer case. You can call and ask for Mike M. if you have any questions.

Questions: What is the recommended modification to allow this system to clear the PTO drive? Do we bend the pipe to go below the frame?
Question By: Mark Weller on Mar 4 2017 2:32 PM
The driveshaft for your PTO will go in same spot. You will have to run the exhaust pipe to the outside of the frame rail to work.

Questions: I bought this system from you and find that I have a PTO going to the winch up front is in the way over the first crossmember. What is the fix (other than removing PTO) Thanks
Question By: Mark Weller on Oct 25 2016 12:09 AM
If you have a PTO on there then the stock exhaust system has to be modified to fit for clearance or the PTO removed.

Questions: I have a stock CJ2a it needs a new 12 volt starter and this exhaust kit. Do you have the starter for the 134L engine 12 volt and do you combine shipping?
Question By: John Moats on Sep 30 2016 1:57 AM
If it is the original starter than the correct 12 volt starters will be: AA4113-12V as an original replacement and A1245-12V as an after market replacement. Both will work. Thanks

Questions: I have a 1969 CJ-5 with the 225 Dauntless V-6. Will this exhaust system work on it. I am having a hard time finding a new exhaust system for my Jeep.
Question By: Ed Priest on Jul 17 2016 6:44 PM
The V6 in the Willys used a number of different manifolds so the pipes changed. You will have to make it at a local muffler shop.
