Glasspack of Turbo
 

Hey. i finally got some money and first thing i want to upgrade is the muffler. My plans are to remove the cat and replace the muffler. The only muffler resources i have are glasspack or turbo.

Im leaning towards the turbo muffler

Neither cherrybomb sounds like crap on teh ecotec. my buddy got one on his 'balt its embarrassing

Do a chambered muffler on a four cylinder, turbo or glasspack either one will sound like rice.

I've heard Flowmasters on a 2.4 Cavy once. Loud as hell, and sounded like shit.

ANY "I" motor will sound like a lawnmower with a glasspak. I've heard the 4.2 I-6 with a full exhaust (Trailblazer) and it sounded like ass

and don't delete the cat, the 3hp gain isn't worth destroying the air around you. plus i'm sure you'll need it for inspection. just get a high flow cat

3hp gain from deleting a cat? :haha:

I gotta ask where you heard that. Maybe a 3hp gain on a 400HP car, maybe

I don't know exact numbers but i know its low lol

i would end up getting a camaro style muffler just so i can run my duals :yahoo:

if i can get my hands on my friends welder, would it be hard to run duals and what would the advantage be?

I'm gonna do duals just cause i want to be unique around here there are a million aleros around town here so im gonna be the one with the modded car not just a run of the mill stocker :yahoo: but still look stock in a way

Are u going to do dual muffler or a single muffler with a dual outlet.

im gonna do a camaro style which is a transverse muffler so its single in dual out

oh nice i bet it will sound great.

im hoping so cause i have a cannon on mine now and its just too damn loud i can't drive down the interstate and still hear my radio so i really need to do something about that so i am gonna change it up!!

when you make a dual exhaust how do you fix the bumber because it only has a grove on one side. wouldnt it look bad?

I will figure it out when time comes

Update. Just put in the turbo muffler. Sounds pretty good.

Next I'm going to remove the res just behind the cat

^^ I wouldn't

i have a custom made exhaust on my ecotec and i have a glasspack
i have a video if your interested to hear it

Why? Its not like its illegal to not have a res.

Sure. What size pipe and what kind of muf and cat?

Its not illegal, correct. But it will be really loud and extremely annoying. Not to mention sound real rice

But I want loud. What if I replaced with glasspack?

i did 2.5 inch catback with no rez outta dynomax. driving up hills blows now... low end torque is gone. u can throw in a glasspack as a resonator if u want something a little more free flowing and it will compliment the dynomax muffler with a nice deep tone and no rasp. but once u take off the res it gets real raspy

Where's the o2 sensors located?

rk sport header factory cat, 2 1/2 pipe, glasspack muffler and it dumps right behind the drivers side rocker molding just turn up the volume for the video

gets really raspy up there in the high RPM's but its a 4-banger so what else can you say :p

i dont think any type of muffler will help a 4 banger, mine is real loud and real raspy

You should send me a pm with a vid, im interested to hear it personally

I don't think its the muffler that makes it raspy cause I replaced mine and it sounds low and no rasp. Its low pitched -4500 but then gets quite when in 4500+rpms. Now if I take off my res, I'm sure it will get raspy. So its not the muffler that causes the rasp

That's what the resonator is there for, is eliminate the drone of a v6 or v8, and the rasping of a 4 cyl
