first performance mod.. wahoo!
 

My girl's getting her first official "performance" upgrade tomorrow:yahoo: ! I'm having the local exhaust shop install a cat back system with a Magnaflow muffler and a 2.5" pipe (debated for awhile on the size, read many posts, finally decided). I'm excited :). I don't expect much gain yet, but I'm getting a CAI in the next week or two, and some headers pretty soon as well, so I'm sure I'll be happy in the end :). And the whole cat back system is costing me less than 200, which is very nice. After all these things I can finally get my girl tuned.. then I will be very happy. Just thought I'd share that with you all... I'm done now...


Wait that's a lie, not done. I think the price includes them taking out the resonator.. I know little about exhausts, but I know the resonator makes it quieter. If I have the option, should I keep the resonator or just replace it with the 2.5" pipe? The guy said the Magnaflow will have a deep pitch on my 3400. I'm looking for it to sound nice when I get on it a little, so I'm not sure if I should keep the resonator or not... hmmmm..




Now I'm done.

oh, too late now are gonna be addicted.......once the speed bug hits you there are no known cures.......

I have a magna flow .. put on yesterday with 2.5 pipe.. I dont have a high-flow cat, because im going to cut mine off soon. but i love how it sounds. the 3400 shouldnt be too loud without your resonator. IMO you would like it, i love mine

edit:: I have the 3400 as well.

sweet... the guy at the shop said high flow cats are a long time myth, so he said I shouldn't worry about that. I would say he's lying to cheat me out of money, but by saying it he's actually losing money.... haha, I don't know.



do you happen to have a sound clip or video of your system?


ha, i keep editing... did you notice any more pull by just getting the catback done? I'm not expecting one, but it would be nice if maybe there was a little;)

i added you on facebook, i have 2 pics of the magna there, and ill send my video. give me a sec
.
edit:: i didnt save the right one so ill have to get a in car and drive by later or tomorrow. and to be honest, i was so stoked about getting mine done that i cant answer. It seems like there might be.. it feels like it added slight torque which you will probably notice.. maybe im just r-tarded and was so amped i imagined it, but i swore there was. not alot, but something.

haha yeah that's how I'm gonna be. "whoa dude, I totally gained like 2357 HP and 42784534 ft lbs torque."


haha no but really, that's what I like to think at first.. I gotta keep myself in check sometimes.

Just for reference, this is a 3400 V6 with headers, 2.5" exhaust with a Magnaflow resonator and muffler.

Yeah I like it without the res on, and I'm still standing by what I feel. I do think it adds some torque.

resonator is useless. ditch it. lol

this is true :scpimp:

wow that sounds niiiiiiiiiiiice. i hope mine sounds half that good.

I don't know....maybe I'm just a wuss.
Scot (Oldsman) has my old cat-back, which is 2.5" pipes with a Magnaflow muffler and no resonator. I just thought it was too loud.....sounds great on his 2.4L Twin Cam though.

+1 for no res for me!

....

no... cats are useless.. res are worse... in Indiana we dont have emissions tests therefore it is ok to cut off your cat, you just need an o2 sensor fooler thing.

well, I live in a Nazi state. I need the cat. lol

thanks for ruining our planet.

you know, one 747 pollutes more in one take off than a daily driven car would in a whole year. cry to somebody else about pollution.

haha I want my cat there... I don't want it too loud. I'm just saying the guy at the shop said it's best to just leave my stock cat on unless I need a new one. Yay I can't wait to go get it done :)

PLEASE PLEASE PLEASE keep your catalytic converter installed.
If it was me, I'd keep the resonator in for now.
Drive around for a while and see how you like it. Anything we tell you about sound is just our opinion after all, and yours will probably differ from ours. :)
If you want it louder, then take out the resonator. It's a lot easier have it removed later than to decide you need it and have it welded back in.
