Let me start by saying this, I value my gas mileage and still did this, about two weeks ago I removed my rear muffs, nice little sound, no drone at all, couldn’t really hear it on highway speeds, no change in MPG. Last week I removed the last two, leaving just the resonator and cats, first impressions.... DRONE, but nice growl from 2500-4000 rpm. My city MPG obviously decreased by roughly 2 mpg, my highway stayed the same. Haven’t posted in awhile so just thought I’d start a conversation, what exhaust changes have you guys done?

Only replacing rusty parts. I may try to take mine apart on my 97 and patch it up good at some point. I was wondering where you got too kambam.


I have the opposite desire to you. I want the exhaust to be quiet.

I can understand wanting that, I’ve been doing lots of work to the car just haven’t been posting, finally got a new windshield, recently ordered new hood hinges (100$)to put on my new hood..... she’s coming back together nicely.

Pondering doing the rear 2 mufflers

if you do just PB blast the crap out of the bolts, mine would not break free even with air tools, had to buy a pipe cutter, took only 2 minutes to cut it off.

JohnAndic

my rear mufflers are probably the best looking part of my exhaust system so I won't be losing those anytime soon.

Sin1UZFE

What do ya mean? I'ma have pipes extend to the back to look stock just give me some slight rumble

JohnAndic

I mean its not rusty/got holes in it. If you want to remove them go for it. Still, lots of work for a louder car.

Sin1UZFE

No rust that I've seen. Shop charges $100 to cut them off and weld pipe to the back.

If the videos I've seen are to be believed removing those gives it a growl when punching it not necessarily when putting around town

i've just done the rear 2 mufflers, i just wanted a little bit of subtle rumble that wouldn't be overly obnoxious... one day when my car was at the shop for something i asked my mechanic to just unbolt the rear 2 mufflers for me just to see what it was like, and i liked it so i had him weld some pipes in place of the mufflers so i wasn't getting exhaust being let out right under the car

my friend described it as sounding like vin diesel's muscle car lol so i'm happy to stop there

JohnAndic

Sounds like a damn truck to me.

Sin1UZFE

Love it, gonna do mine!

I have been wanting to get an electronic exhaust cut-out for just before the Y into the 4 mufflers, and then add 2 mufflers back in. So I can have the obnoxious drony loudness, hit a switch, and get subdued cruising quietness. These variable cut-out mufflers from Quick Time Performance look real nice: https://quicktimeperformance.com/p-3...c-muffler.html

Stroock639

the mic doesn't quite do it the full justice but there's definitely some truth to that lol... at 2000 rpm under load there's definitely a bit of that going on but when you're cruising along it's just a quiet dignified burble

Sin1UZFE

I like it, quiet at idle and cruising then scream when laying into it
