Ok, I did the muffler delete a couple of weeks ago and I love the sound. I have a magnaflow xpipe layin around and was wondering if I put this on inplace of the resonator, will the goat be **** loud. I've heard varied reports from people locally...some say it will be loud as hell...some say it will be just a hair louder...but lots deeper. I'd figure I'd ask all yall, cause yall know best.

Had the magnaflow xpipe installed this morning inplace of the the resonator. The sound is awesome. Car doesn't have that "cherry bomb muscle car" sound to it anymore though......but it's more mellow at idle now...but when you romp on it.....it sounds hella mean. Has that flowmaster hollow kind of sound. Interior noise went down also. Highway noise was reduced to cruise also. It reduced the raspiness of the exhaust also.

I am very pleased with the outcome.

I know you PM'ed me about this so sorry for being late. Busy round here. Anyway, in the interest in maintaining some amount of backpressure, I'd leave it be. I was tempted to do this as well, but I'm leaving mine alone.

I've heard of x-pipe resonators and just plain old x-pipes, like in that picture. I'm assuming that the plain x-pipe would be louder on the interior.....

Isn't our resonator pretty much a muffler "before" the mufflers? Thinking about cutting out the resonator and just splicing an x-pipe in (magnaflow) before my flowmasters....just the x-pipe itsself its a whoppin 207. :willy:

Is the "X" pipe the same size and shape, basically a direct fit so to speak? Is this price from the shop that did your mufflers?

BTW, my K&N is on it's way. Wasn't sure if you were aware of that.

Later!

The X-Pipe was purchased from Summit Racing for 79 bucks. MPE-10791 http://store.summitracing.com/defau...eywordSearch&DDS=1&N=115&target=egnsearch.asp
2 1/2 in and 2 1/2 out. All my friend did was cut the resonator 2 inches from the flange connecting it to the end of the exhaust manifolds. The xpipe is almost as long as the resonator...friend had to weld on just a short piece of pipe to make it connect.

So basically..I'm running full straight pipe fromt he cats back. I would think the interior noise would have gotten louder (my nissans did that) but this time it didn't. The droning actually gotten lower.

I will try to get some sound clips of it. Just need to get the production camera from work.

Look forward to it as well! So you did the muffler delete also? I'm thinking of that route and not sure about the sound.

x pipes will normally lower noise , lower resonance and make exhaust note slightly higher pitched. I have a stcok exhaust except for removed resonators and an x pipe.. In normal driving its actually quieter than stock (thats what i wanted) but when you go full throttle it sounds mean, to me at least ,sounds very "Ferrari-esque"
This is in part due to the fact the 04 has both pipes exiting close together.
On 05s the effect on sound isnt as noticeable but it is is there..
Youll also gain a few (3-5hp) over an hpipe or straight pipes. By combining the two sides in an x it uses pulses from one side to scavenge exhuast for the other side and vice versa.
There are many clips online of aftermarket systems with xpipes on GTOs that can help you decide.

Paid $65 bucks for muffler delete and paid 50 to have xpipe installed. On the xpipe my friend just said to pay him whatever I thought was a good price....so how much an actual muffler shop charges..I don't know.

Sorry for the delay! I shot a bit from my work parking lot. I got it loaded in the media100 and I just need to get it in a format to put on here. Just like most have said..it doesn't sound as good on tape as it does in person. Just a bit longer and I'll post it...I have to share the editor with a co-worker and we have been slammed with editing work.
