I'm a proud owner of a 03 screw 4.6 and have just installed a K&N FIPK and want to upgrade my exhaust system. Does anyone have any suggestions on the type of system?

THANX!!

 

Talk to BigDeal........he has the stuff!! Magnaflow sounds great and does great performance....but I got screwed on my screw......BigDeal did it right.

Flowmasters are good also...just really loud...all the time. Magnaflows are just nice sounding. At idle you can barely hear them. They are deep and throaty when you accelerate. Neighbor up the street has a supercab with the 4.6 and did the magnaflow on his truck. Sounds fantastic. And he loves it. He tried the flowmasters and took them back. Noticed more performance with the magnaflows. Hope this helps you.

 

Call Mike Troyer (i.e. Troyer Performance) and he'll set you up. I've bought just about all my mod stuff through Mike, and he's absolutely terrific to work with. His knowledge on our trucks, as well as his customer service, is even worth paying a slight premium for. Here's where you can get the Magnaflow #15609 catback system (which is what I have and what you're looking for): http://www.troyerperformance.com/cg...catalogno=15609

Tell Mike I sent ya!! Take care.

I have a 2001 Screw. I put a Borla, single exhaust, cat-back on last weekend. Installation wasn't too bad. The Borla sounds very good. Not too loud but loud enough. I'd stick to Borla or Magnaflow. JMO.

 

I guess it depends on what you want out of the system.

Do you only want to change the sound and remove some of the backpressure ?

If so you can look at a lower cost mod of replacing the factory muffler alone. Look at which muffler you want, say a MagnaFlow, and find which noise level you want ( i.e. size ) and order up on that fits in the stock location ( might need some additional SS pipe to make up the difference ).

The other route is if you want to change the sound and reduce back pressure, and want to change where the dumps are at. Then you are looking at a cat back system, with different tail pipes. Want an out of the box forward DO dumps, then it is a Bassasni, Gibson, or Borla. Looking at these you need to decide which type of tip you want, the Gibson ST has square tips, Borla that intercooled tip ( not my style, but maybe yours ) and the Bassani is a slash cut.

Next question, do you plan on a True duals, maybe including long tube headers and high flow cats later on ( or maybe now ?? ) Then just use a muffler only swap and save the cash for the true duals. I put a Gibson ST system on 1st, and then took it off 14 months later for opting in a True Dual Bassani system. Dumped 300+ down the drain on that one....

I guess if you can use some of this as a guide line and let us in on what you are looking for today, and maybe in the future if you have plans would be helpful.

 

I got the Gibson super truck exhaust for 300$ about 1 week ago, low and behold I find f150guy.com and they are selling stock lightning exhausts in the classifieds for 50 bucks, dude grab one up, good sound, nice exit location (in front of rear tire) and it's cheap as anything.

 

I don't think the stock lightning exhaust system is flow engineered to work with our stock n/a engines. Correct me if I'm wrong.

 

I don't know if the stock L xhst is flow tested per say, but I know that the Bassani kit for the L on a N/A engine works, with HP increases ( only have the G-Tech numbers at the moment, need to find true Dyno time yet ).

I would say yes you can get the stock L system, but why go to the work of making true duals to put a DI/DO muffler on it, without a X pipe ?

If it is a standard cab, short bed, then you might have problems fitting in the stock L muffler and a X pipe if you try to retro fit it.
A SCab and SCrew this could be done, but why. X pipe before what is akin to a H pipe in the muffler.

So for 50.00 that is a good price, but having to go to the work of cutting out the stock Y pipe, and fab up the pipes to the stock L muffler, spend a little more to get a good SS X pipe and SS SI/SO mufflers, and bend up the pipe to match your truck and dump placement.

Sorry to whom ever has the system in the classified section if I just nuked any sales chance you have. Maybe they won't listen to me. That is always an option...

 

Is there any place to order an H or X Pipe for a true dual exhaust? I have a take off Harley Exhaust System that I was going to put on my SuperCrew but I have to fashion an H or X Pipe because I can find no one that makes one.

 

Call Mike Troyer, he has the SS X pipes, I thought they were made by MagnaFlow..maybe I'm wrong about the MFGR. Mine is a Bassani brand ( probablly both at made at the same place and just get stamped with a different name .

I guess you can try the other sites that people post ( don't recall any right off hand maybe bigexhaust.com ?? that almost sounds right ).

Don't bother with the H pipe. If it is a stock system, then the muffler has a H pipe of sorts built in. H pipe is an equalizer only, doesn't do squat for xhst gas velocity.

 

hiiiiiiiidehooo, I might be a little bit ignorant, but I am pretty sure the lightning exhaust is si/do so you would only have to cut your stock muff off and put the lightning one in, (basically). as far as flow tuned or anything, my gibson s/t is a straight through pipe with fiberglass around it for sound absorption it doesnt have any mazes or junk in it so i would'nt call that flow tuned, Id be willin to bet the lightnings is the same way, one of the svt guys could clear this up, thanks

The new looking pipe is a Bassani Cat back for a S/C engine

Thanks for the enlightenment sscully PRIMO job on that system that is definately one of the sickest set ups ive ever seen!!


my child hood was rather normal, summers in rangoon, luge lesson's. when i was insolent i was placed in a burlap sack and beaten with reeds, your basic stuff.

 

No problem. That is why I was waxing poetic about cutting the factory Y pipe, and going to all that trouble to put on a DI/DO muffler.

I had an unfair advantage on this specific section of the thread, I already did all the research on the Bassani for for the HD SCrew and for the L, and what the differences were between the xhst system on the L and HD vs the N/A 5.4L engines.

 

I have a FLOWMASTER cat back system on my screw 5.4L. I LOVE it!!!! But that is my opinion.
