Celica Forums General Discussion Exterior Greddy Evo II Exhaust mod!

For those of you who have purchased a Greddy Evo II cat-back and are not happy with the sound, REMOVE the mid-muffler/canister. I recently went to a custom exhaust shop and had a piece of aluminized pipe bent to fill the void. No one in my area had the capabilities to bend stainless. Don't worry about it being to loud or ricey. The sound is deep and is tastefully loud. I have driven past serval cops and not one have bat an eyelash. So for those of you who like the Performance figures and look of the Greddy Evo II, but are not happy with the sound, this mod is a must. If anyone has any questions feel free to contact me.

Removing the whole Muffler?

How much did that run you?

I have an Evo II myself.. would liek to find something to make it louder, but still wanna keep it Passable.. but I could always put the Muffler back in when I go for SMOG/Inspection

Cali is a lot more strict

yea, i have the evo 2 also...and i want the sound to be more louder. can you take some pics of the part you bented?

also if you can make a sound clip that would be helpful

Cat-Back? Im so confused Thought they don't make cat-backs! Only axle?

I live in Pittsburgh, PA and the exhaust set-up I have is passiable because the canister that leads into the tip is considered a muffler and exists out the rear of the car. The cat is still there and from knowledge that is where all your emissions/smog etc...goes through and is eliminated. It ran about $80. I will get pics up this week. I am not sure if i can figure out the technology for a sound clip. But I assure, you won't be disappointed. I first the EVO exhaust because I was worried about it being to loud. Once I put it on it was no louder than stock, it just sounded better. After I did the mod, it is a perfect blend of sound and tone. It does not sound cheap. The sound will draw attention, but not negative attention.

I did that mod on my Greddy Evo a few months ago and it ran me $40. If you look underneath your car you can see that there is more than just the canister you see with the Greddy emblem on it. You can't miss it, it's right in front of your suspension. The sound is awesome, I would say just perfect.

Was jsut talkign to my friend about this he is goign to take my mufler section into his shop and bend me up a new pipe. Ill get some video / sound whenever I acualy get it from him

Blonde question:

The greddy evo exhaust came in 2 parts, right? the 4" tip part and then the squarish oval part which is the muffler...right?

so taking the muffler out and running a pipe straight to the tailpipe doesnt effect the cars Performance or emissions test

Yes the exhaust came in two parts. The piece that sits in front of the rear suspension is the piece I removed. I did not notice any change in Performance. Just sound. As far as emissions you should still be cool because you don't mess with the cat and the rear canister that forms into the tip is a muffler too. The place I had the work done is a Pennsylvania State Inspection Center/Certified and they performed the work.

Hey please post a pic of your work... i got the evo 2 and im not very pleased with the sound...but i dont want it to sound ricy either...how loud is it?. i got the gts and i go into lift alot... here is a pic of my exhaust before it was installed. so you are saying i should replace this piece?

Ax the piece closest to the shoes...
My main concern when I bought the exhaust was how loud it was going to be. When I installed it, the exhaust was to quite. After I did the mod, I am extremely happy with the sound. It wasn't that much money to do. Worst case you spent $80 or so...

pic of your mod?

bump

so you remove the second canister?

any sound clips?

nomatter what exhaust you go with you can always have the resenator removed and a piece of pipe welded in. i wouldnt worry about the cat since its already as free flowing as you can get. i had a custom exhaust on my car for a while that had no muffler, it just had the canister and it was pretty loud however i didnt mind it, i eventualy had it removed and bought the evo because i had a backpreasure problem

I have pics on my profile.

does the sound, sounds like the EVO exhaust but louder

I had the same thing done to my tanabe super racing med.

good luck getting passed your next smog if you live in cali

Im thinkin about gettin this mod done to my evoII. But im not sure what really to ask for when i go into a shop. Can any of you, who have had this done, explain what i should ask for when i go into a shop. also what should i bring. i really dont want to go in there and look like im talking to myself. i also dont want to get ripped off either. i wanna know what they'd be doing. oh yeah another thing...how long does it take for them to bend me a pipe.? i know its a lot of questions but hope someone could help out. thx

damn, that greddy muffler looks huge...

shambhala can you sell me that pipe that they bent for you?

Guys Monday im going in to have the pipe made. Ill make a video so you can hear it will also snag some pics of it while its on hte lift.

Im in cali Im getting a pipe w/ flanges made so I can put the muffler back in for smog and shit jsut incase

Ok jsut had the new pipe installed and I cant stop smiling, I LOVE the sound! Will shoot some vid tomarrow after work.

^^^how long did it take them to do it?

Took my friend about 2 hours to make it, he is relativly inexpierenced with the mandril bender, and we had to custom fab a 3" flange, so if they had a flange on hand and he had more exp would have been shorter.

But got it done for a 12pack of Bud Light.. so pipe set me back <20$

sound clips yet?

My Dad has the Video camera somewhere waiting for him to get home from work.

The place im going to doesnt have mandrel bending. would that be a big differnce to the regular bending?

not really I dont think its a small section, and they will be using 2.25 or 2.5 Piping anyways

Ok saving movie right now. Will be posting shortly

bah cant delete post. reuploading it got messed up...

Forgot my camera so I couldnt get pics. But got audio

Shitty vid quality but sound is all that matters eh? I tryed to get the full spectrum of sounds. Had my Windows down and Sunroof open for these.

guys I just got this mod done today and when i fired her up...a huge smile hit my face. sound is awesome. loud. deep full sound like that eclipse in the first fast and the furious. the mod took about 1.5 hours, cost 31.95, the only thing is that my tip sits a lil lower now. about 1 inch lower which doesnt bother me. the sound is sweet. all you evo owners , this is a must.

i really want to do this mod...can someone please post a pic of the part they tooked off?

they took off that top part. the Big can..

ook so they welded a pipe to replace that? what size is the pipe?

2 and a half im pretty sure... but if you take it to a shop they'd figure out just by lookin at it

Its accualt a 2.25 Flange at the Tip end, and a 3" flange at the Cat end. but they can figure that out

Hey guys, i did love this mod the first day i got it done, but now it turns out that its buggin the fuck outta me because its loud. im not saying that its really loud as it kazuma loud , what im saying is that im not the type( as i just found out) of person that likes the loud exhaust. so what i did was put the evo resonator back on. so heres the bottom line, if you like loud, get it done, if you like quiet, keep it the way it is.
