Was trying to figure out whether to post this or not but indecision is killing me.
Got the injectors in, emanage, wideband wiring, front feed y, all I need to do is my oil drain tap but I need to get my exhaust replaced from mostly stock. I'm not tracking the car or anything, it is a dd. Not looking for huge numbers either, car will be in boost every once in awhile. I'm planning on running 2.5 from the catback but I can't decide on a muffler. Some people said magnaflow will be too loud but the 2.5" Dynamax super turbo muffler looks too small physically to me since I have a stillen kit. Should I:
1. Get the 2.5" Dynamax with a tip anyway
2. Get the 3" Dynamax no tip
3. Tsudo muffler
4. Magnaflow 14829

One reason for indecision is it rains here in WA often so the dynamax might have to be replaced every so often and didn't really want to go through the hassle, but let me know what you think?

 

I have the dynomax turbo muffler and love how it sounds, its not loud but has a great sound. 3" is what I have.

 

is your car going to be turbocharged or supercharged?

 

Turbo Neal. If I put more thought into it initially I would have went s/c. Yeah, i'm not into loud, i've been trying to listen to clips and all to get an idea. I like the way the dynomax sounds.

 

Dont go with 2.5 dynomax, i did and got pressure drop and sacrificed spool up in my rear mount turbo setup. I suggest getting the 3" one, cuz these dynomax mufflers sound sexy.

 

I'm really leaning toward the 3". Your car sounds awesome btw Streetz. Someone was asking in another thread about rear mount, you should consider making a kit.

 

Thanx, well i have received alot of messages even from non maxima.org members about me making a kit for them. But i have no space or anything to store parts specially piping. And iv gone through alot of troubleshooting to perfect my setup, if I made a kit for someone and they ran into a problem they wouldnt be able to pin point exactly whats wrong, without asking me.

I suggest going with the 3" no matter what muffler you get. I used 2.5" it caused pressure drop so i put a cutout between the turbo and the muffler, thats how i solved my pressure drop lol.

 

3''> 2.5'' for forced induction

 

I would go with a 3 inch. The 3 inch will definitely be better performance wise. I can't comment on either muffler since i haven't heard them however. <shameless plug> You should just sign up for the cattman exhaust deal<shameless plug>

 

my dynomax ultra flow ss welded 3" and dynomax 3" bullet resonator is pretty quiet.

 

What was you running before the 2.5 muffler.

 

He was running a straight pipe off the turbo to the back of the car.

 

Well yeah it dont get no better than that. ANy muffler compared to open down pipe will suffer some
