What 3inch N/A exhaust setups are people running on there cars?

More what muffler/resonator setup is not to loud to raspy on a 3inch

 

any "educated" people in here? This site used to be good.....

 

 

Why would you want a 3" exhaust on a N/A car?

 

The "educated People" are doing it

not again...

Because its beneficial on a 2.2H motor

 

just outta interest, is it 3" o/d?

 

The inherent problem with a 3 inch exhaust is that most of the commercial ones availabe are straight through design, and it is very hard to quiet down a 3 inch hole. So, for almost straight through free flowing performance with near stock sound level, you might look into using a 5 inch diameter Magnaflow muffler for your resonator, and a Dynomax or Dynomax Turbo muffler.

Hopefully, you will have the supporting mods to make a 3 inch exhaust work for you, a good header, and if you are running one, a good cat. The carsound round metallic has excellent flow for your application.

 

the h22 doesnt have to be modded to benefit from a 3" exhaust. Its not a damn b16.

here's one I made for my car.

 

By supporting mods, I meant intake and header.

 

So far im going to go with a flowmaster delta 40 series muffler 3inch, vibrant "race cat" all mandrel piping, just not sure what resonator to use to help quiet the noise.

thanks for the posts so far

 

The rule is pretty much the longer the resonator the deeper the tone. With a resonator, you need to make sure there are no baffles, and that the inside diameter doesn't shrink down. I am using a 2.5 inch diameter pipe, 4 inch round body magnaflow for a resonator. Nice deep tone, not too loud, not raspy. A member of an RSX forum is using a 5 inch diameter 3 inch pipe diameter with good success in low noise and flow.

Aren't flowmasters baffled? If you really want a flowing exhaust, you need to find out how many cfm each part of the exhaust will flow.

 

i understand people put the 3 inch exhaust on to relieve more backpressure and all, but wouldnt it just plain sound like rice!?!

 

i think mine sounds good.

whats your setup consist of for your exhaust?

 

RMF narrow
2.5" magnaflow cat
17" vibrant resonator

 

so how long are the 4inch and 5inch magnflow mufflers you guys are running 14", 18" ?

 

yes finally very nice! the intelligent choice is to go 2.5'' if you must! Unless you like rice an you yourself to

 

^ silence ricer

I am using the 18 inch, 2.5 inch diameter, with a 2.5 inch diameter inner core, 4 inch round. If I could do it over again, I would get the 5 inch round. Magnaflow makes a 2.5 inch, 4 inch round with a smaller diameter inside the muffler, so you have to be careful when you buy.

 

I ran 3" straight with thermal R&D muffler, no cat, no res. - Loud and also gets raspy. Now I have the Vibrant metal cat + 18" res. and it's got a deeper tone, not raspy at all but still a little loud for me after 3K but what do you expect from a 3" exhaust on a 4 cyl.? It's not that bad for daily driving but I do want to add the Vibrant Ultra quiet res. on there to keep it quiet until 4K at least.

It's hard to drive fast and be quiet at the same time in a Honda. The exhaust note may sound cool and all but I don't want the attention it gets.
