huck731 Posted December 17, 2012 Share Posted December 17, 2012 ok, after tires, my truck will be getting a new exhaust system. I looked on youtube and imho the thrush turbo sounds like crap on the 2.5. I was thinking about either a magnaflow (which sounded really good on my 2.0l 99 vw) or a cherry bomb extreme. thoughts, comments, and opinions GO Link to comment Share on other sites More sharing options...
87Warrior Posted December 18, 2012 Share Posted December 18, 2012 Generic muffler house replacement. I have never heard a 2.5 make a nice tone with fancy mufflers. Link to comment Share on other sites More sharing options...
jeepsouth Posted December 18, 2012 Share Posted December 18, 2012 Of the two you mentioned get the magnaflow for sure. Link to comment Share on other sites More sharing options...
jimoshel Posted December 18, 2012 Share Posted December 18, 2012 Run over a protruding rock and tear a 6 inch gash in your stock 2.5 muffler. Produces a sound no after market can duplicate, although now I have to turn the stereo up a little more. Link to comment Share on other sites More sharing options...
Harley Posted December 18, 2012 Share Posted December 18, 2012 Hey Jim, a grinder woulda worked better. Easier to find too, I recon. Link to comment Share on other sites More sharing options...
Bounty Hunter Posted December 18, 2012 Share Posted December 18, 2012 I agree, get an OEM type replacement muffler. I've heard no aftermarket muffler that does the 2.5L justice. There's no performance benefit of installing a performance muffler on the 2.5L engine. Link to comment Share on other sites More sharing options...

TGTgoHARD Posted December 18, 2012 Share Posted December 18, 2012 My 2.5 came with a cherrybomb.... sounds bad. Not too loud til you get up to 3000 RPM then it sounds like a rice rocket.... go OEM style Link to comment Share on other sites More sharing options...
huck731 Posted December 18, 2012 Author Share Posted December 18, 2012 so basically I'm stuck with a $#!&ty sounding exhaust no matter what. Link to comment Share on other sites More sharing options...
AMCJeepMJ Posted December 18, 2012 Share Posted December 18, 2012 so basically I'm stuck with a $#!&ty sounding exhaust no matter what. If that's how you wish to look at it, sure. You're never going to get the deep sound a Corvette or angry bees sound of a stainless exhaust equipped Civic out of a 2.5. How I like to look at it is if you can't make your exhaust sound good, make your exhaust sound quiet. Your neighbors/parents/spouse will surely appreciate your efforts in sound suppression. As a bonus, you will be able to hear your stereo more clearly, and not have to yell for passengers to hear you while carrying on a conversation.

87Warrior Posted December 19, 2012 Share Posted December 19, 2012 so basically I'm stuck with a $#!&ty sounding exhaust no matter what. No, no, no. If it is quiet, you can't hear it. If you cannot hear it, it cannot sound '$h!#y'. Granted, you must realize we all are voicing our opinions. What you like is probably different. If I had $$$ to spend and I wanted to experiment, I would try a Hi Flow Cat and glasspack with 2.5" pipe past the glasspack with the 2.5. Heck, my 2.5 with the exhaust cut past the gutted cat wasn't unbearable, but I didn't like it. Link to comment Share on other sites More sharing options...
Eagle Posted December 19, 2012 Share Posted December 19, 2012 The reason NO aftermarket exhaust can sound good on a 2.5L is that you have a basic 4-cylinder engine with a mild factory cam and a single exhaust, and the compression ratio isn't especially high. The pulses are evenly spaced and the cam has moderately long duration and moderate overlap, so by the time the exhaust gets to the outlet of the tailpipe it's more or less a uniform flow, not a series of individual pulses. If you want it to sound more "macho," you'll have to invest in a more aggressive cam, something with higher lift and shoter duration that will generate more distinct power pulses.

(2.5") http://s867.beta.photobucket.com/user/huck731/media/bridgette/car001.mp4.html my stepdad and uncle who are into american muscle and v8 trucks admitted to liking the sound of my exhaust.

gogmorgo Posted December 19, 2012 Share Posted December 19, 2012 Wow... for someone who doesn't like quiet... is the car even running??? I've watched it a few times, and I'm still not sure that I'm not hearing a plane fly over head... Link to comment Share on other sites More sharing options...
Harley Posted December 19, 2012 Share Posted December 19, 2012 Swap out the motor for something with serious horsepower. Its a waste of money trying to get a 4cyl to sound like something its not. Stick with OEM until your ready to beef it up the right way and get the sound you want. Link to comment Share on other sites More sharing options...
dasbulliwagen Posted December 19, 2012 Share Posted December 19, 2012 I have a Flowmaster 50 series on mine with a gutted cat. Not loud or annoying, but has a nice growl under load, and is only slightly louder than stock with a smooth rumble at idle. I would do this setup again in a second if I ever get the chance.

I've watched it a few times, and I'm still not sure that I'm not hearing a plane fly over head... it was recorded with a canon powershot camera, it actually sounded awsome in person. had a loud drone at hwy speeds though, the ex-gf hated it and it did bother me sometimes (not to often though) Link to comment Share on other sites More sharing options...
