Default x-pipe muffler

someone recently posted pics of a Magnaflow 2 inlet - 2 outlet muffler and said it is basically an muffled x-pipe. and said that it might be a good option to quiet down the exhaust. another person said they run two mufflers after the x-pipe and two at the back.

when i discussed this w/ a friend he said it is not wise b/c u would be changing the back pressure from the back of the car to the front. when i asked the person who originally posted the Magnaflow 2in/2out muffler, he said that it shouldnt make a difference.

i figured i would ask opinions in the hybrid section, since u guys think outside the box and maybe have tried this. i want my car to be quiet at idle and at low rpm highway commutes. i dont mind robbing the car of a few hp w/ a more restrictive exhaust, but if it is going to restrict alot of hp and some tq then forget it.

wut do u think about a "muffled x-pipe" w/ bullet mufflers at the rear?

Its actually a Dynomax Ultraflo X Performance muffler. If you have the room to utilize this thing and some straight thru muffs at the back, it wont build up back pressure. It will be the quietest way to go tho.

his muffler was indeed a MagnaFlow. if the site wasn't down i would post pics.

i looked up the above mentioned muffler and it would be a better route. thank u for the reply.

i need to check my ground clearance before i purchase either muffler. on my old car my down pipe was so low and got caught on everything i dont want the same problem w/ this car.

not the MagnaFlow site. it was on another forum. it wasn't actually called an x-pipe. someone jus bought their dual in/out muffler and took pictures saying that its essentially an x-pipe. i will see if i can find the post and i'll pm u the link (i dont know this forums rules regarding links).

i think the DynoMax one is a better option though. i feel more comfortable knowing that the company refers to it as an x-pipe.

Ahh... just got your PM.

Its actually a perforated core and not actually the same thing or principal as an X-pipe. Both the Magnaflow and the Dynomax products are of the same idea and internal construction. I feel that this would make an excellent resonator but it lacks in the operational principals of what you are trying to gain from running an X-pipe.

The flomaster resonator that in used in their ZR-1 kit would actually fit your application the best. It was designed narrow to fit down the center of the shaft tunnel and would do the same basic thing as an X-pipe... but in a single pressure vessal package. I just dont know if Ray will sell them outside of the full kit.

If I could use one on my system and actually make it fit.... I wouldnt even think twice. It sounds totally badass.

Hi,
Just saw this and I think this is the one your talking about

http://store.summitracing.com/partde...5&autoview=sku

This is what I'm looking at for the Monza as there isn't a lot of room under the car.
