mewantsa87gnx Posted February 14, 2005 Report Share Posted February 14, 2005 I need some tips for my 95 Monte Carlo z34. And yes I did search the forums for an answer, however I did not find an answer that satisfies me. I have only had this car since June of 2004, and I have been looking for advice about the exhaust almost the whole time. My girlfriend owns a 97 Mustang V6 with an exhaust that makes it sound like a V8. Well I want that, plus some a performance increase. Does better sounding exhaust and performance go hand in hand, and can I gain either/both from just a new muffler? From searching the forums I gather that Borla is a favorite but when I visited their site I did not find a muffler for the Monte. Anyone know a model number? Also I know that the 60 series Flowmasters are popular, but I would like to hear a sound clip before I commit to anything. Anyways thanks for any responses ahead of time.

sonyman87 Posted February 14, 2005 Report Share Posted February 14, 2005 flow 40s sound like a v8 at idle.. they tend to be raspy if they are cold with a free flowing exaust no resignator at 2.5-3k rpms. flow50s sound really nice.. magnaflows are also pretty good. If you get some put on and are still not satisfied replace your resignator with a glasspack type muffler or put strait pipe in its place.

Lee Posted February 14, 2005 Report Share Posted February 14, 2005 If you do pick up a glasspack. I highly recomend the flow tech "purple hornies." Dumb name--great pack. If you find a store with them and other brands....compare steel thickness and insides. You'll see what I mean. Mine is now over 2 years old. It quiets the rasp big time. The exhaust is quieter in general for about 9 months. Then the deeper tones build and get better and better. You may want to paint it as it really is purple, sick purple.

Canada Posted February 14, 2005 Report Share Posted February 14, 2005 All the mufflers you guys mention really sick flow wise......which is bad for performance.......which is the entire idea behind exhaust in the first place. The best mufflers you can buy have a perforated core (a bunch of holes) and are straight though. For instance...a Dynomax Ultraflo.....which is what I have and recommend.

90TGP Posted February 14, 2005 Report Share Posted February 14, 2005 I have Dynomax Bullet mufflers. They are pretty much enlarged straight pipes with holes along the insides. $30 a peice from summit. It's nice and loud with a V8ish rumble. 8) Quote Link to comment Share on other sites More sharing options...
Cornerdealy Posted February 14, 2005 Report Share Posted February 14, 2005 just replacing the mufflers have practically no affect on performance, especially on these cars. Redo the whole exhaust from the headers down and yea then maybe the muffler would do something. But as it is, they are just for cosmetic reasons. If they make ur car sound nice then go for it.

Euro Posted February 14, 2005 Report Share Posted February 14, 2005 yeah as for performance/high flowing exhaust, Dynomax Ultraflow, Bullets, and Super Turbos are great. they're all straight through and sound awesome! Quote Link to comment Share on other sites More sharing options...
Lee Posted February 15, 2005 Report Share Posted February 15, 2005 Perhaps I should have mentioned earlier. I went duals with Dynomax super turbos and cat removal. It was extremely raspy, very embarrassing. So I had the Flow Tech Purple Hornies glasspack put in where the cat was. Problem solved. The Flow tech has scallop cuts inside like a high end motorcycle exhaust rather than the piddly little holes found in a thrusher and others. If you look at my www site you'll get an idea of the dual look. The first guy I went to wouldn't work with me. He was too dumb to see that the exhaust could be routed under the suspension rather than through it like stock. When I told him they are doing it on the net, he told me to have my net buddies do it then. If I ever get busted for no cat.....I'm telling the cops he welded it up for me and said the glasspack was a high flow cat. A$$hole. Oh yeah, I know the tips are too far out.

90TGP Posted February 15, 2005 Report Share Posted February 15, 2005 I have a high-flow cat, and 2.5" piping along with my Bullets. It sounds a little raspy when the exhaust is cold, but after it warms up, its like a V8. Quote Link to comment Share on other sites More sharing options...
Dirty Rockstar Posted February 15, 2005 Report Share Posted February 15, 2005 I need pointers on this as well, lmao Quote Link to comment Share on other sites More sharing options...
skalor Posted February 15, 2005 Report Share Posted February 15, 2005 Hey 90TGP, do you have any sound clips of your exhaust. I was thinking about running the same mufflers and I was wondering what they sounded like on a TGP. Quote Link to comment Share on other sites More sharing options...
GTPrix Posted February 15, 2005 Report Share Posted February 15, 2005 Canada, How much are those Dynomax Ultraflo mufflers? Drew Quote Link to comment Share on other sites More sharing options...
chadz34 Posted February 15, 2005 Report Share Posted February 15, 2005 The stock exhaust for 3.4's are sick. They sound really good especially in the lower rpm's when they rasp i have no plans on replacing the exhaust becuase there are no proven hp gains so why waste the money Quote Link to comment Share on other sites More sharing options...
90TGP Posted February 15, 2005 Report Share Posted February 15, 2005 skalor, I don't have a laptop or a mic to take a soundclip. Sorry. Quote Link to comment Share on other sites More sharing options...
JoroCorona Posted February 15, 2005 Report Share Posted February 15, 2005 The stock Exhaust is pritty good on the 3.4 DOHC. DO NOT go with the Flows. Flows sound good on pushrods, not DOHCs. Glasspacks are cheap and they work well on the 3.4, however alot of people complain about the raspiness of the car. The only way to truely get a boost in power is gonna be a straight exhaust, and that is gonna sounds nasty... and not in a good way. It will more then likely be whiney and high pitched when running hard. Quote Link to comment Share on other sites More sharing options...
Lee Posted February 16, 2005 Report Share Posted February 16, 2005 I believe, at least in our case, that piping diameters, and the amount of back pressure created by those various diameters is seen in torque more than horsepower. Smaller diameter, less freeflowig, more backpressure = better take off and low speed accelleration. Mid-range diameter, less backpressure is going to give you a better flow at highway speeds = better mileage, better passing. Huge diameter, no or low backpressure = a pile of manure that can't even get off the line and dogs out when given gas. That's the biggest problem with amatur demo derby guys. They like the pipes coming out of the hood, no back pressure, doggy acceleration. But then I could be completely wrong. I was going for Highway mileage and passing with my exhaust. 2.25 piping, non mandrel (no shop could do it around here) from the down pipe to 2.5 mufflers. (good price on left overs) Quote Link to comment Share on other sites More sharing options...
