exhaust Mods

Has anyone done EX modifications to their Aurora? I was thinking about swapping the stock mufflers for dynomax or magnaflows. are these worth the cost? will it effect the fuel economy?
thanks

i'm gonna try taking my cat off tomorrow and see what happens

I have magnaflow mufflers on mine -- well worth the cost. The sound isn't too loud, and fuel economy wasn't affected at all as far as I can tell.

what about the tone? is it a deep rumble or sound like a ricer?

It's a deep tone --- like what a v8 should normally sound. I'd never let my car sound like a mini go-kart!!!

it would actually be a very large go-kart :P

I want to get magnaflows for my aurora what model did u get and how much were they?

to be honest -- can't remember what model, as my paper work is lost somewhere in all the other paperwork for my car in my girlfriend's stash. I'll try to find it later this weekend. I had my front breakpads put on with the mufflers, and that total cost was around 400.

anyone know of a good exhaust shop in the DFW(north texas) area?

I know it sounds lame but you wouldn't believe your ears if you heard it yourself. I put 12" glasspacks on mine. I saw a guy have it done on his '02 LS and I was totally amazed at how clean and throaty it sounded so I figured a 4.0 Aurora could only sound better. I was right. Close your eyes,think about a new Z28, open your eyes and see a front wheel drive car. If the radio's on, you can barely tell a difference. Mileage hasn't changed, if anything it's gone up about 1/2 a point. You will, however, have lots of girls in boys clothes driving Civics staring you down. Feel free to laugh. Total cost from the 'Y' pipe with hangers, $78. I'm still in the design stage on the tips.

Your SES light will come on! 95 and up cars are OBDII and have o2 sensors in front and behind the cat. I know of o2 simsulators for F-bodies not sure if they'll work on the northstars?

YES! BE WARNED!.....u need them for it to run right.if you wanna mod it, get a performance cat, but ur in for a world of trouble if you scrap em!!!!

FYI- '96 and up OBDII. '95s have the same connecter but not OBDII.

Well guys, i stopped at my favorite muffler shop today & asked the owner if he thought i should scrap the resonator ,to get a little tone, or if he suggestede mufflers. I told him i didn`t wanna break the bank.
He suggested an economy turbo muffler (Imco) i think it was, (like an economy version of a dynomax), and i told him i didnt want it really loud or annoying. He said lets start with a pair of those, then if i wanted it louder he would take the resonator off after. He did the mufflers only for $100 total, & it has a nice "rumble" at the tailpipes:-) but isnt loud by any means. I may have the resonator taken off later, but for now this is a welcome change.
These cars are too awesome to have totally quiet exhaust.
I had him lower the factory tips & bring them out the back just maybe an inch more than stock & they look SO much better!

****BTW !::: The factory mufflers are A JOKE!!!!!!!!!! I looked inside the inlet end, and the pipe reduced down to almost ONE INCH DIAMETER!!!!!!!! I was apalled!!! They must`ve been TRYING to hold the car back from the factory!!!! I don`t see how the airbox mod can do any good with stock mufflers. But, rest assured that if you want better flow, it`s WELL worth your money to lose the stock mufflers!

Yo whats up guy just wanted to let you that this does deserve to be pampered as a solid V-8, thats why i hooked my Aurora up with a set of Dynomax turbo 2s and then I put a set of 92 chrome vette tips on it the tips took some modifications but they sit right at the edge of the bumpers and really make the ass end look even that much more vicious esspecially with those fat 255-35-ZR20's sizing it up. Well the kit is being put on as we speak. What a christmas present my woman takes care of me. if you want to check it out the car is posted on sounddomain nc Aurora is the name any further questions holla at me on My yahoo for a quick response [email protected]

I've been saying this forever, an exhaust mod on the Aurora is highly recommended. The car chokes on its own exhaust...literally. The system is so restrictive, anyone with a performance exhaust swears by them.

Anything is better than stock. By better I mean better for the car not just the V8 junkie like me.

i REPLCED THE STOCK MUFFLERS WITH DYNAFLOW 2 1/4 IN AND 2 1/4 OUT MUFFLERS. aT THE SAME TIME I ELIMINATED THE RESONATOR AND RAN 2 1/2 PIPE ALL THE WAY BACK TO THE Y. SOUNDS OK, NOT SPECTACULAR BUT IT RUNS LIKE AN ESCAPED CONVICT. BOUGHT THE MUFF'S FROM SUMMIT AND THE LABOR AND PIPE WORK COST ME $135 LOCALLY.
