Cat delete Pipe and back pressure

[40Xshooter]

Straight Pipes

I've read some good pro's and a few con's about this issue, so I thought I'd throw my 2¢ in. Well I've been riding and building bike's for better part of 45 years, and these issues of to run a baffle or no is up to the rider and his expectations. Personally I run the cat delete and baffle in my F3, I too ran it for a few weeks without the baffle and now a few months with it, bottom end torque increased with just the cat bypass, where I gained with the baffle was in midrange throttle response, no flat spots. How much back pressure is needed, that I don't know, the only test equipment that I kept after I retired was my fat ass and it tells me that the combo of the cat delete and baffle work together to move the F3 like it should. I'll say this, I gave an ZO6 Corvette an education on stop light to stop light running, he didn't even pull up next to me at the light, I just looked back at him and waved! I haven't done anything that dumb in 25years, but it was fun!
There will be a lot of opinions on this issue, so use some judgement as to what you're after. I quit running drag pipes on my Harley's because all that did was make noise unless you're running wide open all the time, so I went to some kind of baffle. Good Luck with your choices. Again just my 2¢.:doorag::doorag:

Thanks for that post! I was waiting for someone to mention HD! I, too, come from an HD background. Most of us went to 2 into 1 pipes for power. The guys running straight pipes just made noise. I'll qualify that by saying that a few of them knew what they were doing by having their motors tuned for WOT which is where the pipes have their advantage. For around town riding the guys with the drag pipes lost power, fuel mileage and stoplight-to-stoplight shots........but to each his own...

BTW, I don't have a trike yet. That will change next April when the lease is up on the Mustang....
