Yeah I knew that the factory does not incorporate a Cold Air intake. However; I now see you have some clever ideas in the works...

 

Not the best pictures yet I have not had a chance to take pictures on a speed bump.
My driveway from the tarmac entering the cement area at -5degree then jumps to 22 degrees leaving 3 inches of clearance. this would be taller the regulated state speed bump height. My drive way then continue at a 12degree incline but by then the car is level. There is 6 1/2 inches of clearance from the bottom of the little scoop to the ground.

I will say I ordered another scoop exactly like that one to mount on the other side more for aesthetic and asymmetry.. (the looks of balance)

Using my garage fan as a wind source I was able to measure volumes of air with my Dwyers Magnehelic differential pressure gauge

 

I finialy purchased a new block of aluminum, for the new spacer. The last one pictured in previous posts served well but had some short coming that were unexpected. The next spacer will be much better for the purpose intended.

 

did a brake fluid check and am in the first stages of indicating to do a fluid replacement. So intil I do a complete fluid service I did a fluid change in the brake fluid reservoir to at least make me feel good.




I have more but they are in my first maintenance report book from day one.

 

First post on forum. Scrolling through your Mazda 3 mods, all i can say is WOW and AMAZING, Thank You.
I have a 2021 CX5 Carbon edition (non turbo). The only engine mod so far is K&N air filter.
I would like to install an axle back exhaust and would like to know why you chose the "RacingBeat" muffler vs other brands such as Corksport, Borla, etc.?
I am looking for a low to moderate exhaust tone, nothing loud and obnoxious that would p--s off the wife.

Thank You

George thank you for the kind words and compliments ,
The Racing Beat is stainless steel fibers. This means that it will break in over a few thousand miles. As with most of these constructed muffler's there is a predictable sound increase. At this point it is very quiet at highway speeds but if I throttle into it has a nice low tone sports car sound. My wife still does not know I installed a "performance" muffler.

 

Thanks much for your reply. I am leaning toward the Racing beat axle back muffler however also considering the Borla muffler. The Borla customer rep. told me the baffle material inside muffler is a "ceramic" material that doesn't break down.
They make a Touring low tone version that may be suitable for me. Do you have any experience or info. on the Borla muffler that may help me in my decision between the two brands?
Thanks again.

George because I set this thread up to be a none technical thread I sent you a pm. Your questions and my responses may invite others to take this thread way off topic .

 

After a weekend trip to Oregon and taking a few off road excursions I needed to do a complete washing from head to toe.
