I had a magnaflow exhaust with some custom tips put in... it sounds amazing..
The only questions I have are...

1. I have the option to cut out the secondary muffler and just straight pipe it through.. which will make it a little louder...

or

2. Chop the whole thing and have an X-pipe fabricated instead of the Y pipe that goes over the axles right now....

or I can leave it as is...

Anyone have any suggestions?

 

Not that I'm an expert at car mods , as far as I know if you apply #1 option you might decrease your lower rpm torque thus you need to reprogram your PCM against this lose

 

I'd say chop it all out including the cats then go with 2 straight pipes all the
way back to the two mufflers! Then sell the O2 sensors on Ebay!

OK, I know that won't work guess I'm still living 1987 technology that
would let you get away with that!

Option one would be fine and I doubt cutting out the resonator would
cause a need to reprogram the computer.

Do you have a current sound clip I can listen too? Also what is the stock exhaust setup and pipe size? Also what setup did you go with and what size pipes?

 

I dont have a sound clip...
I dont know how to put it on the computer...
lol..

It was a custom setup.. magnaflows and custom porsche tips..

I think I might go with the x pipe..

 

Rosemont, if you are looking for the most power from out of the exhaust system, then the X-pipe arrangement will be the best. I would not recommend going over about dual 1.75" pipes though. Like was mentioned, making too free flowing of an exhaust system will hurt your low end torque. If I remember right, the factory piping is a single 2" pipe (possibly a 2.25" pipe). Going with the dual 1.75" pipes, you will get a freer flowing exhaust (which will help with the higher RPM power) without having a negative effect on the low end torque.

If you have more questions, let me know. I would need to know the series muffler (70, 50, 44, 40, etc) that you are running and the size pipe that you are considering. Then I will look at my car and see what the factory piping size is and go from there. Keep in mind that going with a muffler with a lower series number in it will also minimize the backpressure of the exhaust system, therefore the low end torque.

I do have to admit, the 3.0L engine in my car needs a bit of help above about 5,500 RPM. It seems to fall a little flat and doesn't have the pull like it does below 5,500 RPM. An upgrade in the exhaust system would help with that.

What model magnaflows did you go with? I would too opt for the X-pipe configuration. In most V-config engines this will help increase torque and is a smoother flow than a H-pipe. I am not sure what the mad obsession car makers have with 3 and 4 mufflers. If the optimal mufflers were chosen to begin with the added cost and weight of yet another muffler would not need to occur. I for one want to hear my car before being forced into a hybrid.

 

its actually a Y-pipe...

I dont know the model of the magnaflows.. but I'll ask him today..
I'm going back with a friend to get his bmw done.

I'll try to get a sound/video clip up of the exhaust before I put the X-pipe

 

pics and sound clip please

 

Well heres a pic of the exhaust....
I'm trying to get th sound clip uploaded...
but it doesnt sound very good on a phone...

That looks pretty cool..Nice job.

 

Thanks man..
I have the sound video on my computer now...
It sounds better on the computer than the phone.. so its decent..
youtube is down right now so I cant upload it yet..

Is there any other way to upload videos?

dun dun dunnnnn...
lol..
Theres the clip/
Let me know what you guys think!

 

sounds good,you should make a driveby vid too

 

Thats too hard..
lol..

Ill post another vid of the x-pipe setup in about 2 weeks..
Should be sounding like a ferrari..
lol

 

Hey rosemont, Lamborghini sounds better lol
