I'm just looking for additional input in my situation. I am in the process of buying paNX2K&SE-R's turbo classic and I was wondering what I should do with the exhaust. He has a VRS group buy 3" Mandrel bent exhaust with Magnalfow resonator and SS muffler and also a new test pipe. I really don't want droning or anything when I'm cruising (I do a lot of highway driving) but I don't mind a little music in my ears when I go WOT. Matt mentioned a silencer but I couldn't find any for a 5inch tip. The only other thing I could think of is adding a second resonator or highflow cat instead of the test pipe. I tried searching all of the archives but I couldn't find anything conclusive. Any suggestions to reduce the noise would be appreciated or else I might be forced to go stock exhaust
:p . Thanks for your help ahead of time guys (and gals I guess).

dude just buy the car! if the exhaust bothers you put the stock exhaust back on

With the turbo and the mentioned exhaust it should'nt be all that loud or drone. If I were you, I would buy a high-flow cat.

yeah, a cat will tone it down somewhat.

Stuff the longest Dynomax resonator you can underneath the car.

Put the stock exhaust back on? That will choke and eventually kill the turbo.

Don't do that. :)

It already has the long 3" Dynomax resonator :)

SERprise In WV: I have heard a lot of stuff going back and forth about killing a turbo with a stock exhaust. I know it does cause backpressure but I have also heard that it will not hurt the turbo... the performance will just suffer. So, let's come to a conclusion on killing the turbo.

bl200sx and sr20ser: I was really thinking about scrapping the test pipe and getting a high flow cat but do you know if this would really change the noise?

egg: Don't worry man I am definately sold on the car, I'm just wondering what to do about the exhaust. There is no way I am passing on my chance for a turbo classic:cool:

Guys I have a similar exhaust. 3in dynomax resonator and magnaflow muffler with a 3in test pipe. It was loud as shit. I then ended up putting the 3in cat in for emmissions, but it still "drones" on the highway. I was thinking about using two small resonators instead of the big one...similar to the Greddy system for the WRX.

hummmmm........well you might want to go with 2 resonators. What I run, is a 3in cat, 3in exhaust to a Magnaflow w/3 1/2in tip, but I like it kinda loud, and this is not my daily driver.

I run down pipe into two 16" dynomax bullets., no exhaust Doesn't sound to bad to me. With piping and muffler, it would be pretty quiet

Matt basically summed it up by telling me that you can't get a quiet 3" exhaust. My question for you guys is what is the power difference between 3" and stock. Obviously it is significant but like how many hp? I enjoy power but I am wondering if it is worth the noise. Like I said before I do a lot of highway driving. Is there any other options like a 2.5" exhaust or would that present the same problem of damaging the turbo? Speaking of which, does anyone have any conclusive opinion or information on damaging the turbo with a stock exhaust?! I am torn between keeping the exhaust and adding a silencer (does anyone know where to get a silencer for a 5inch tip? or the best place for silencers), a high flow cat or some other configuration. So what would you do in my situation? Also, would a silencer present the same problems that a stock exhaust would (if it does indeed cause probs)? Thanks again for the input.

On my 300zx, i was running just an open exhuast with only the stock cats on it, and it was LOUD! Since its dual exhuast back from the headers I put a 24" glasspack on each side, along with just a cheap OBX muffler, and it went from the one extreme of LOUD to almost dead quiet inside the car with the windows up. Outside the car you still hear a little roar if you get on the throttle, but not anything like those fart-cans on hondas.

I was thinking about a glasspack, its just that a lot of people are saying resonator so do you know if the glasspack is better than a resonator? The quiet inside is exactly what I'm hoping for but I'm getting more and more discouraged. What size exhaust were you running (2.25-3")?

Here's the only info you need to know:

T28 turbo setup, stock 1 and 7/8"-2.0" exhaust: 14.57 @ 95mph
T28 turbo setup, 3" exhaust from dp back: 13.70 @ 99mph

Almost one full second.

Think that small exhaust isn't hurting the car? ;)

Wow...well umm that looks pretty conclusive:eek: ! I didn't know that it would affect it that much. Is that your car? The mph seems a little low for the 3" setup for the time but what do I know. What I am thinking of doing is not purchasing the 3" exhaust that is on the car right now, getting the car for cheaper because of this and going with asspipes (w/resonator of course). Does anyone have any other ideas (I searched and I did see some alternatives) or do you know which 3" setup is the quietest? Thanks for the help once again guys.

What about 2.5"? I'm thinking that this might be a good compromise between sound and power but I was wondering if you could provide more of that informative help SERprise:D
