Straight pipes
I dont want anyones opinion on if this would look good or not. I want someone who knows what they are talking about to give me a straight answer. I am thinking about making a custom side exit exhaust with no muffler just right out of the exhaust manifold out the side of the car. Will this do any damage to my engine?
|
to your engine... no... to your ears from loudness and possibly body panels from flames shooting out... yes
i would not do straight pipes to the side... if your gonna do straight pipes, do it all the way back because since the sides are near the middle of the car, it will make it REALLY LOUD inside the cabin. |
not to mention the smell! you would make yourself sick just trying to get to work in the morning.
|
alright. What do you think if i put a cat in there? any different or same results?
|
nope.. sorry, dont do side exhaust. i ran open exhaust after the cat for 2 days and the cabin was SOOOO loud with drone. if the exhaust exits near the middle of the car or underneath it, it just fills the cabin with noise. you wont like it! plus then you will have empty exhaust holes in your rear bumper?
|
what did a cat ever do to you that you want to stick one in a pipe with 1500 degree scorching heat?
|
put a cat in there and you're pretty much negating any gains you are trying to accomplish
|
why not have custom exhaust and straight that bad bow right out the center of the back bumper :Eyecrazy:
like right where the rotory symbol is on the back bumper I think it would look crazy |
I think you should put zoomies straight up through the hood personally :lol2:
|
Nah, all the cool kids are routing the exhaust from the manifold to a 6" pipe that sticks straight out the front of their grill. flames shooting from there makes you gain like 50WHP due to intake heat pressurization and interflux designation.
I know this. |
yes it will hurt you engine, epic fail saved
|
I still think an exhaust straight out of the middle of the back bumper would be uber tIIIIIIIIIIght :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:
|
noise isnt really a concern of mine considering this car is not a daily driver. its an 05 with 18000 miles on it. i guess your right about the exhaust holes though. i just want the sound. without an exhaust the car sounds so raw.
|
Have you heard it without exhaust?
Massive rasp... A guy in our local club went for ultra-lightweight, decided to scrap the exhaust system.. He just put a pipe straight from the headers out the rear rotor accent in his bumper. It's plenty loud. Go do that, it's not expensive. |
Remove your midpipe and drive for a day. You will be crying and your ears bleeding at the end of it. And most likely a ticket, too.

i've done it. https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/different-kind-exhaust-modification-164090/ |
almost positive u will get a nice ticket for that one....also running straight from headers to side will have almost NO backpressure so any performance ur trying to gain it will not happen performance will just go down!!!! Now if yo do straight pipes to a Y pipe and split it and run it out the rear with a good resonator in there it may b better but I still dont' recommend it

this stupid question has been asked before.
got an idea. do it and get back to us on how it works!!! beers :beer: |

anyway, i say go for it... run a straight pipe however you decide to set it up and see how long you can take it before you decide it was a bad idea :) you said you just want the sound... you ever heard a rotary uncorked? and ppl think ricer fart cans sound bad and loud.... |

^^stupidest comment in the whole thread... no backpressure = less power? back pressure makes you moar faster and moar furiouser:banghead:
is it just me that notices this????? beers :beer: |

ok everyone that think ZERO backpressure is the best ride around with NO exhaust straight out of the MANIFOLD see how much power u have there and see how much fuel u use!
OP do it if u want to it's ur car not ours.... |
ok ppl.....now less backpressure will not DIRECTLY reduce power....however with less backpressure the motor will run more rich....we all know(or should know) that a 14.7:1 AFR is PERFECT now with smaller or no backpressure the motor will run rich....say10:1 or 9:1 something like that so without being able to adjust AFR (we are talking about a stock motor no AP or tuning device)
Now yes a slightly rich mixture like 12:1 will cause BETTER PERFORMANCE however running extremely rich will not increase performance....And we have no way of knowing how rich it is running without having an AFR gauge to keep an eye on it.. The motor will run rich which will of course burn more fuel. when the plugs ignite the entire Mixture is not burned up because of too much fuel so there is lots of fuel being dumped into the exhaust system..... Therefore SOME less backpressure YES will net more power because of a slightly rich mixture however Zero backpresure will burn more fuel and make an EXTREMELY rich mixture and will not NET ANY extra power... Like i said running straigt from manifold is almost zero backpressure and an extremely rich mixture having straight pipes with a small resonator or Y pipe Xpipe and running out the back of the car will give enough backpressure to lower the AFR to a SLIGHTLY rich mixture and net more power.... |
i like the sound of an uncorked rotary as well.
i have a catless midpipe, combined with arguable the loudest catback exhaust out there, and i love it. it sounds great to me. i think some people just need to toughen up. |
