Does anybody know about any cars that come with 2.5" or 3" exhaust systems stock, that would have a 2.5" or 3" inlet muffler?

I like to drive cars that fly under the radar. My last car had stock wheels off an RX-7, a black painted front mount intercooler, and a stock catback exhaust with an electric cutout on the downpipe. I would like to continue this trend with my new car, but I don't want to do the electric cutout thing again. It was too loud when open and too slow with it closed. I want to do a standard catback exhaust system, preferably in 3", but 2.5" will work. The part I want to change from the norm is the muffler. I have heard of Honda guys running mufflers from higher powered stock cars on aftermarket exhausts with good results and that's what I want to do.

The muffler has to be a single inlet, probably between 14-18 inches long and either single or dual outlet straight at the back. 240s have a standard exhaust layout where the muffler is oriented straight toward the back of the car with the back end of it sitting right underneath the back bumper, no weird crossover system or dual tailpipes. I already know that Magnaflow and a bunch of other people make kinda-sorta-stock-ish looking mufflers but they're not stock enough for me, so please keep it to stock or stock replacement stuff.

 

the 99+ mustangs are 2.5"

 

Do they have separate canisters for each side (I'm assuming they're running dual exhaust)? F-bodies and a lot of other V-engine cars have those horizontal crossover mufflers that just have two pipes sticking out of them at 90 degree angles facing back. If the Mustang has two straight, 14-18" by ~10 inch by ~5 inch oval mufflers, that could be a good place to start looking.

 

I suggesta trip to the junk yard bro .Take a tape and size up a couple of them .

 

you probably won't find a muffler of that size in the junkyard, and if you do you probably wouldn't want it anyway

try a C6 muffler, i hear they're pretty stout, and they're variably baffled or something, no they have valves

hell, i don't know

 

integra type r and s2000 mufflers have 2.5" inlets and flow pretty well.
wrx mufflers are 2.5" also, but i dont know about flow rates for them.

 

BMWs have dual exhaust, or "twin" I should say. Pipes are only 1.5"-2" on most of them, but the newest 7 series (2003 or so) has a decent sized exhaust, as well as vacuum actuated.

 

I made this about 2 months ago using a megan muffler. Total was around 175 for the muffler and tubing and I made my own flange.
It has a 3'' inlet and a 3 1/2 out. Im going to eventually cut off the outlet and weld on a 3' outlet to make it even less noticeable.




Im guessing you dont want to pay $400+ for an aftermarket exhuast but theres Circuit sport if you decide to go that way



Or this one from megan with stock looking dual tips:
Megan Racing Type 2 Catback : S13 1989-94 240SX

 

that is so sick ^. I wish they made more than just S chassis exhausts. You can always buy OEM shaped (typically oval) can, and paint it, which is what i did. Here's what it looks like:



believe it or not, thats a 3 inch thermal r&d catback. A little bbq grille paint goes a long way. Of course that only covers part of the equation, you'd also want to pick something on the quiet side and then don't drive like a d*ckhead.

I actually got pulled over the other night for my exhaust, but then let go when I claimed I didn't like loud exhausts, that I was into car stereo (all true). Combine that with a clean record, plus 30 age on my license, and a general respectful attitude, the officer only gave me wishings of safe travel

The tip is going to get replaced by something smaller and more OEM appearing.

 

The S2000 muffler is 2.25. I know the type r muffler is slightly larger than the S2000 muffler, but i dont believe its 2.50. Reason being that I have an S2K muffler on my car.
