How loud will this be?
Hey guys, I need to re do my exhaust. RIght now its just a 2.5 inch downpipe with a cat, and thats it.
What im going to do is a 2.5 inch downpipe that merges into a 3 inch exhaust. This new system wont have a cat or muffler (money reasons). So my question is will the new exhaust be louder or quieter than the open downpipe with cat? Also, will the exhaust without muffler be loud enough for cops to care? |
prolly depends on where you live and how many eople complain i live in alabama and drove a mustang gt with straight pipes... (No Mufflers or cats) and i never had any problems..
:) IMO it shouldn't be to loud ill be running straight down pipe when i finish my turbo install untill i can get it to a shop :) |
i have a 2.5 downpipe that merges into a 3" piping. its dual with only a resonator and its fucken loud but not annoying loud like ricer exhausts. i also have a cat though. and a test pipe sitting in the garage waiting to go on

Fucking loud. If you don't DD the car it might be doable, but it's seriously loud. Like, "shit i'm going to get pulled over" loud.

I have a full 2.5" turboback system on my car with no cat or muffling whatsoever. It is now louder with the mufflerless exhaust than it was with just an open downpipe.

I can't speak for a miata, but on a 1.8t A4 I know that a 2.5" straight exhaust with just a cat and no muffler was liveable for about a year. It wasn't really loud until you were at WOT.

more like "shit I'm too loud to run at the track" loud.

I have the Magnaflow race series muffler on my Miata and it is great. No louder than my RB system I had when I was NA (but I also have a cat). I think I paid $120 installed at the muffler shop.

I'm in a similar boat. I'm really wanting to do something cheap for exhaust.
Would just that muffler really quiet the exhaust down enough? I'm thinking i'd like to do a high flow cat with that muffler and 3" piping. I think i'm a little more concerned with being quiet than you. |

lol at the muffler! Thats an awesome comparison...glad you did that.
My budget is also 200 or less. What are you doing for flanges? |
i brought my whole car to a local mom and pops muffler place, with a muffler that i bought on ebay for 60,
paid the guy 270, he made me a 3 inch line from the downpipe back |

I am makeing a new downpipe in that budget too. I think ill just split it after the downpipe and at the diff, and just use good old 2 bolt flanges to mate them together. Thanks urgay! Ill go with that magnaflow I linked alittle bit ago.
