Greetings. I hope you all had a nice day. I had to work but it wasn't too bad. Anyway, lest cut to the chase. I own a 1995 SE. I replaced the old, rusty exhaust with a used SVT exhaust I bought from a very nice Gentleman from Milwaukee. Charged me $130.00 plus the hanger (You really should make or buy this hanger if you plan to do this). Anyway, my nephew helped me install it. Very slick and easy, bolts right up.

Now, I have searched this sight thouroughly about exhausts and the consensus I believe was that I should replace the stock resonator with either a glass back, straight pipe or magnaflow, specifally, the Magna Flow 10435. This is a straight through muffler that is 28 inches over-all.
I bought it off E-Bay for a total of roughly $60.00. It took two weeks to arive. I would have been better off searching the internet and going with a different retailer and spending about $5.00 more. Most likely it would have arrived sooner.

Anyway, the guy who installed this muffler was a little "miffed" that I chose this one. One, it is NOT offset and Two, it goes almost all the way from the Cat flange to the first bend. He said he would have prefered me using the 10445 which is 20 inches oe the 10425 which is 24 inches. In hind sight, I propably should have used one of the 4x9 Offset/Center Mufflers, 11225 which is 20 Inches or 11255 which is 24 Inches. The guy charged me $70.00 to weld it on. I'm not sure if I should have spent the money or not. I really can't tell if it "Sound's Better". At Low RPH , it "Runbles" per my wife and at higher RPH, I can't tell the difference. I wonder if I lost a little acceleration because of lower pressure. In the long run, I just hope to increase the highway gas mileage. I have a 42 mile comute each way and drive between 70 to 75 miles per hour.

Anyway, I hope someone will find this information useful.

Sincerely,

Johnny T. :cool:
 
MagnaFlow all the way..I run a 14415 4" round straight threw style muffler for where my stock resonator was as many CEGer's run this style as well. My car as a good low tone and sounds great over all when driving and accelerating. I spend I believe 54 somthing shipped from Ebay. My local exhaust shop charged me 30 bucks to put it in..I had to do get this in there since i had a straight pipe there that was welded in and i just had alot of rasp..No more rasp..
 
That's weird that the guy was complaining about it's length. Since my headers, y-pipe, and cat pipe all are 2.5", I went with the 2.5" Magnaflow (10436). I also had the shop replace the crush bent "s" bend in front of the resonator... welded up to a 2.5" trubendz flange. It fit perfectly, which is why I'm not sure why the guy complained.

After the install I did have really bad drone.. from around 2,000-3,500 rpm, usually off gas. I read somewhere here that the drone will go away, as well as the overall volume will reduce, after about 2 weeks. Sure enough that was true. I'd say the loudness now is about between OEM and the day I had the resonator installed.
 
I've got the 10435 on my car. It sounds good, nice deep tone at idle. Definitely quiet enough for the daily driver. But, IMO its a little too quiet...
 
backpressure isnt really an issue on a 4 stroke engine, like stated above.

what changes the power is the scavenging effect, in the first few feet of the exhaust. basically an exhaust pulse in motion downstream from the port actually acts like a vaccum to the exhaust coming out of the port or anywhere in between there and the downstream "pulse". the only way i have noticed really in my experiences with exhausts to actually make your car slower, is to gut the precats, or gut the cat. if you put a straight (test) pipe in place of the cat, you will usually see a small gain or stay the same (per the butt dyno) but i think headers vs. gutted precats is the only part of the exhaust that will make a noticible difference (and the Y pipe) unless we're talking about a heavily muffled exhaust or an overly large exhaust.

so the short version is......no the resonator wouldnt make it slower.
 
I have the Magnaflow 10435 on my SVT.
I'm having it removed on Friday. The car is too quiet for my taste.
Wanna buy it? :)
 
nope, I'm in the process of a 3L hybrid so everything else is secondary because of $, I was just curious. thanks
