Help me pick a mid-pipe.

[bunny_power]

I'm trying out an FRPP M55 catback on my 04 and it should come in some time next week and I'm thinking that I'd like to put the mid-pipe in at the same time. Anybody have a guess what would sound best with this thing? Catted vs O/R, X vs H?

My GT had a catted X with packs on it and it wasn't quite agressive enough, looking for something with a bit more bite for the cobra.

Dr. Gas O/R X.

 

[bunny_power]

Yeah, I was thinking about an O/R X, but I think that the M55 is chambered (not sure though) and as far as I know X's do not sound good with chambered mufflers.

i heard an offroad X on a flowmaster catback..2 chambered..and OMG it sounded so incredible from the outside..i dont know how it would sound inside though

 

[travis0712]

o/r x-pipes need straight through mufflers, IMO... they are just too raspy with chambered mufflers.. with cats they are okay. I had flowmasters on my bassani x without cats and it was just too raspy (popping and gasping) more so at smooth casual takeoffs... at WOT - it was very aggressive and impressed a lot of people...

My magnaflows with the o/r x sounds nice - deep, low and quiet driving around town and the neighborhoods... but get on it and it is very powerful... excellent balance.

get a BBK o/r X-pipe. I'm going with bbk longtubes, bbk X-pipe, and flows. Myfriend has the same combo on his gt. I can only imagin how its gonna soung on my cobra.

 

[missouri_guy197]

My Long Tubes/off-road X/Flowmaster combo sounds like poo-poo...As soon as I get some fundage I'll be going with Bassani...

If the M55's are indeed chambered I'd go with an H-pipe...If you want cats MRT is the only one that makes one for the 03/04's I think...

Thanks guys, nobody seems to run this catback so there's no reference stuff on the net. Once it arrives I'm going to check the mufflers and see if it is chambered or a straight shot and then get either an O/R X or H.

...this thing is going to be f**king loud.

u sure that's legal up there? won't you scare mooses or something and then they won't be able to mate and then all the mooses in canadialand will die..all because of you!!!

The correct plural is moose.

On the topic of a mid-pipe. My setup is in my sig. I like it very much.

No ****. I was just attempting to interject some humor into this otherwise technical thread.

Nah, its not the meeses that you've got to worry aboot, those things are dumber than a bag of drunken beavers, its those damn yankee tourists who come up here for the skiing in august and think that you're destroying the wilderness with your loud car. Damn tree hugging pinko yankees.

 

[travis0712]

I thought it was funny - we all need some humor every now and then

I do think the FR500 is an amazing exhaust by design . I haven't heard it mind you, but I think it is chambered until enough back preasure hits it... and forces open a trap door.. then it is straight through... very cool design.. Granted, I have never seen a cutout view of the muffler but I have read a few topics. I just don't see why they wasted the R&D funds on it...

How can you get more HP/TQ than with a solid catback from magnaflow, bassani, or borla? The 2000 Cobra R has a Borla cat-back (why didn't they use that FR500 Cat-Back?)... It just doesn't make much sence, kinda like wiping before you poop... just doesn't make sence.

but if the damn yankees didn't spend their slightly higher valued american dollars up there, how would you buy beer and afford hockey tickets?


tree huggers = teh suck

The reason you don't see too many people running the FRPP exhaust components is because they are out-performed by almost all the aftermarket systems currently available. Plus they are costly. Nobody wants to spend more $$ for less performance.

Really? I remember reading a comparo on svtperformance of basically every exhaust available for the cobras and it put everything at about the same gains (+/- 5 HP) for most catbacks on 03/04s, and that's Borla, Bassani, Magnaflow, Flowmaster, FRPP, straight pipes, etc. Also the M55 was actually the least expensive 3" stainless setup I could find.

 

[bunny_power]

hmmm, another question. Seems that people are losing power running catless on the 03/04s, anybody have any thoughts of this?

 

[travis0712]

June, I will have my bassani system dyno'ed... 3 pulls with cats and 3 without... the bassani system includes o/r pipes that unbolt so you can bolt in the included cats...

I have been wondering this too and they dyno will show... I just can't see how one could loose power without cats..

Only when the car has not been tuned! A cat-less mid-pipe should not lose any torque or horsepower over a catted version once the car has been tuned properly! Just because a mod is a "Bolt-On" don't take that term too literally!
