Exhaust System Help

[Neville Lush]

Haven't done any exhausts for Dodge cars but have been desinging/testing them on R3's on and off since 2005. Phil, it will be interesting IF they do a valid test. have a nice day guys.

Hah Nev, as though you need to read about primary length/diameter/collector design! Clearly you know your ****. If only I were in the land down under ....

Not sure of the significance of the little vid Phil? A valid test is try them as described above. Each pipe tuned to the same bike. I am tipping Bobs pipe more above 4500 and CES ( if it is the one I thnk) better under 4000. Stock engine?

I'd guess you will be right. The CES should have more torque in the lower rps where they are used more. And yes they are both stock motors. Not sure which model CES pipes @R3Tex has. Honestly didn't know they had more than 1.

I don't think they do have more than one type.
There are two types of cans - straight and slash cut.
I believe they just do different colors and have a willingness to make slight adjustments for their customers.

Pleased I have Rebands , Lushy's input into their design good enough for me.

CES make headers with a 2-1/4 inch tail pipe and muffler. They also make headers with a 1-3/4 tail pipe for those that want to run mufflers that suit stock headers.

I have the 1 3/4 inch tail on mine so they could connect to my Foran mufflers. The opening is around 80% the size of the 2 1/4 and as I noted at the time, I may be sacrificing some hp at the top end but the torque is very strong. The way the headers are made it will be a relatively simple matter for me to modify them to get the 2 1/4 tail pipe - cut and weld below the O2 sensor. Might do it at some stage but for now I'm happy with what I have. I certainly haven't noticed it running out of puff all the way to the (increased) rev limit. Have lifted the front changing into second a couple of times.

Thanks, Nev. as you probably know these things often evolve into pissing matches and, generally speaking, there's no reason at all to justify that. This is not a grudge match. Most folks that do this sort of work put their best efforts forward and that needs to be respected. The final decision on which system anyone chooses to use, is a personal one and it is often predicated on subjective variables. Nonetheless it is both intersting and helpful to have objective data available in order to make reliable comparisons and/or fully informed decisions. I have zero doubt that the recent CES option is of very high quality and that it was accomplished through due diligence, careful testing and design methodologies, as well as by a lot of hard work and effort. I hope that the same would apply to making head-to-head comparisons of the tuneable, high performance exhaust systems that are currently available for our beasts!


It would be a real breath of fresh air if it were as simple as all that, wouldn't it?
I commend you for your very pragmatic professionalism!

Thanks, Mate.
I forgot about the pipe diameter option.

I hope any reference to head to head, grudge match, etc isn't aimed at myself or Steel. We are simply riding to Dallas together to see a friend (Stripes) and throw a few hard earned dollars at the Dyno man. I don't think either of us would have a problem sharing the results, but as Nev so appropriately pointed out, we would have to put both systems on the same bike to make any sort of objective comparison. Our upcoming trip is simply an effort on both our parts to get the most out of our rides, nothing more and certainly not intended to persuade anyone to choose one system over the other.
