Exhaust question

[m_eclipse_96]

Hey guys, maybe u can give me an answer on this one. I have a 2g eclipse GST and I wanted to do a little to me exhaust so I went out and got an Arospeed muffler and put it on. Now when I put it on it didn’t make the exhaust as loud as I thought it would and it almost seems like my car is slower then it was b4. Also my boost went down by about 2psi but I don’t know if its b/c of the muffler or the upper intercooler pipe.

So give a response if u think u know what’s going on, any response is appreciated

thanks, jason

anyone?

Why would you just put a muffler on instead of a whole cat-back? I can't see the stock muffler being that restrictive, thus not much HP gain. Get either a turboback or catback and put in a test pipe. Gobs of highway power will come to you.

i just put a muffler on untill i get the money for a catback, the question i wanted to know is y i am having problems with the muffler i put on, not why i didnt get a catback

The problem is that you went the cheap way of doing it...its strange that you boost 2 pounds less...you might just have leaks that occured the same time....just putting a muffler on like you see people do everywhere in the world doesn't do shizznit you need a nice 3 inch cat back exhaust..now if you are saying you are getting a catback exhaust if you use that muffler now you need to get the piping cutome made for that muffler cuz there is no point of buying a Exhaust now and hacking off that mauffler and using your **Ricey** Arospeed muffler..I would just save up and buy a nice whole new exhaust..new or even used they work the same and sell your muffler to someone else...

that's what i did. i slapped a SS mufflerless tip in place of the ugly beat up stocker on until i saved up enough for a turbo-back. do the usual. check your IC piping and all vaccum lines, and intake pipe to make sure everything is on tight, but you probably have already. does your boost gauge read pressure only or does it read vaccum as well? that would show a leak under the hood. any leak caused by the muffler shouldn't hurt the car at all being that it is after the turbo. do you have an MBC?

p.s. paint the center piece

thanks for the info.

i have a boost gauge that reads vac. and boost when im just idling it will read 20psi of vac. and then when i get on it, it will spike up to 17psi of boost then go back down to about 13psi of boost. and no i do not have a mbc, yet

I cant tell you whats wrong....I took my mbc off to spare my engine so I went from 15 psi and stock exhaust to 10-11psi and a pace setter cat back and now its faster than with more boost. for 200 shipped you could have had a 2.5 inch mandrel bent nice sounding exhaust not ricey at all. Its great for keeping your low end torque and rasing your top end hp. good luck.

PS: Dont knock pace setter till you try it!!! best exhaust Ive used, looks stock with a little chrome tip, nice low barley audible sound...until wot growl!! sorry to sound like a vendor.

 

[m_eclipse_96]

i have looked at the pacesetter already and i think that is what im going to get for sure, i work at jc whitney and i can pick it up from there for $165 easy

thanks for your info

 

[DSMeclipse4G63]

sure thing

I've got a 2G 3" pacesetter downpipe for your car. $50. two months old

 

[DSMeclipse4G63]

why so cheap?

 

[m_eclipse_96]

ok now heres another question, about how loud will the exhaust be with out a cat? i want to get rid of it to free up some exhaust flow but dont want it to be really loud or sound like s**t

 

[DSMNightmare]

It will get really loud. Depending on the muffler it will sound like crap too. Mines loud, and sounds like a cesna going down the highway.

 

[m_eclipse_96]

i have heard that by taking the cat off a turbo car that it would be quieter then if u took it off a nonturbo car, is this true?

 

[m_eclipse_96]

?

 

[DSMNightmare]

I don't know who told you that but my car is louder than any NA car I know.

 

[m_eclipse_96]

k thanks

just one thing, vac is measured in mm of mercury not psi.
