Which is better for a TC, Magnaflow or TRD?
Need help deciding on Exhaust for my TC..
TRD I can get for 400 Shipped from McGeorgeParts.com
or the Magnaflow Catback from Precision Muffler for 300
Which is better?? I had a Magnaflow and I loved it on my Eclipse. Basically Im looking for most Horsepower, I figured its about the same..But I've been hearing the Magnaflow is Deeper..Any input?!
Sorry if this is a repost..

You need to get a full answer from Stylis. He is the one who has the Magnaflow system. If you are looking for a Axel back go with the TRD. If you got some extra cash go for the Magnaflow cat back, that will give you the most power right now.

Im not sure if my logic is right here but lets seet.
TRD = Muffler + A little pipe.
Magnaflow = New Pipe from cat back.
Just looking at that I would think the Magnaflow would free up more HP because you remove more of the restrictions of the stock exhaust. The main thing that creates a lot of restriction though is the 2 cats on the car.

ne sound clips? i would love to run magnaflow... but it all depends on the sound quality. If it's something like the catback system for the xB... i might buy it. I love the quiet low tone...and it's rumble as u press the accelerator. Nothing too loud...but enough to be heard.

on a side note.
a cop let me look at his book of driving laws or whatever it is called. and it states something to this effect.
1. An automobile cannot have a excessively loud and/or distracting muffler/exhaust on any vehicle that might pose a distraction for other motorists.
i forgot how the whole thing went. it was awhile back.

I PMed SOILWORK_tC and asked for some more info about the MagnaFlow Cat. I still need some more input on which Exhaust you guys think is better?
TRD Axle-Back
MagnaFlow Axle-Back
MagnaFlow Cat-Back
Im ordering soon. I basically think they sounds similar, but I want most power..but if I go w/ the Cat back I want it 2 pass emissions and 2 be legal. I'll see what SOILWORK_tC says..Post up your preference!!!

shouldn't all catback pass emissions? because it doesn't affect the factory cat. and shouldn't affect emissions, correct?

The company i work for has tested both the TRD and Magniflow systems for the tc on a chassis dyno. i found that neither system gives much of an inclrease over the stock stuff, but the TRD system gained about 3 hp and lost about 2 ft lbs, the magniflow system lost 5-10 hp before 4000 RPM and gained about 1-3 hp from 4500 to 5800. also the magniflow lost 3-18 ft lbs across the hole power band. The TRD system is desighned to work with the TRD supercharger. The sound was louder with the magniflow system but i didn't really like either of them, they got a little tinny at high RPM. most people think that a bigger pipe will make more power but it doesn't always, the cats do not hurt performance on the TC in fact they help build a little back pressure to build more low end TQ the same goes with the stock pipe. thats why the magniflow system lost all the TQ it is too large for the car. i have tested mnay aftermarket parts for these cars and mite be able to answer other questions

So Stylis what is the estimated HP gain for the MagnaFlow Cat? and the Axle? From what I've been hearing the Axle back is around the same for the TRD.
Most likely I'll be buying the catback from you. Any other pics of TCs w/ MagnaFlow? Please POST!!

The Precision muffler looks very nice. any chance you might be able to sell ones with different style tips like UUC Motorwerks does for their exhaust for the 330Ci?
Also, everyone has to remember that rx191 is right... catbacks do NOT always make more power. If you plan on going forced induction at some point, then it might make ssense to get a fat pipe throughout... over than that wait until dyno numbers come out to make sure of the power gains/losses.
Case in point, the HKS Dragger and Dragger2 axleback exhausts made more power than ANY catback that was made for the IS300 for NA purposes. Only situation where people really saw gains for catback was when they turboed their cars.

Just a note , not to put a damper on cat-back systems but with the new LEV spec's you have to be careful if they are not cert. to fed spec.
Section 203 (a)(3)(A) of the Clean Air Act prohibits removing or disabling or altering any emission control device or element of design installed in a motor vehicle designed to meet federal emissions standards. Removal or altering violates section 203 (a)(3)(A) is subject to a civil penalty of not more than $2,750 with respect to each motor vehicle.
Some of the fines for manufacture go up to $25000. per incident
I know in our state this applies to any auto that is licensed to operate on the street whether inspected or not
This usually gets noticed and inforced after you have been pulled for loud exhaust not during a state emissions inspection
