Got XSracemax cams, got an 02 housing, 3'' Buschur DP 3'' test pipe, 3" Catback from Buschur. Got 680cc's SAFC 2, FMIC, 255lph fuel pump, Buschur Upper IC pipe.

Also have, but not installed : Magnus Intake Manifold, 65mm ported TB, TME turbo w/ Single Flapper 10.5, and a Forge WGA.

 

Well, the 3.5'' exhaust that are on the market are TOTALLY OVER PRICED.

HPF = $1000.00 +
AVO = Well over $1000.00

I know you get what you pay for, but imo, I can build one for well under $500.00 INCUDING tig welding every piece from the flange back, and a Magnaflow 4" muffler


I could build a 3.5" exhaust for a little cheaper... say probably around $50.00 cheaper.

 

damn where are you gettin your parts from? i calculated my 3.5" to be about $500 in parts alone....

 

the ams evo has a 4 inch exhaust and so does that black evo from florda i think, call up ams and see if you can get one of theirs.

 

so you want to go from a 3" bushur piece, to a 4" custom and you're still on the stock turbo?

 

ATP Turbo, northern CA For the
piping/bends/transition, flange,gasket, and O2 bung, comes out to around $280.00 shipped

For the 4" Magnaflow Muffler $110.00 for the muffler, free shipping.


diablo2184, my fault, I apologize, there was a typo, It should read, well under $500.00 including full tig welding. I shall edit the post.

haha oh ok! i thought i was getting ripped off.....lol......are you gonna use the magnaflow diesel muffler that has the 4" inlet/outlet?

 

Initally yes. Do I plan on staying on a "stock type turbo" No.

I drive a lot in my car, and especially on the freeway, where some freeway action does accure.

this is not going to be a 4" back from the O2 housing

This is only going to be a 4" back from the Down Pipe.
just a more free flowing exhaust.

 

Yea, the 4" Diesel Muffler 18" body I do believe.

I'm gonna paint the muffler a high temp coated black
Paint the piping high temp black, for that super stealth look.

 

you're going to see little if any improvement. if you still have a restriction in place, (O2 and downpipe) having a straight atmospheric dump after the downpipe wouldn't help much either. You are going to be most limited by the stock turbo efficiency if you try to run significantly more than stock boost.

on the other hand if you're just looking for a science project and something to do; go for it.

 

i felt that muffler and it just seems so heavy

 

exhaust gas is hot. And we'd like to keep it hot throughout the exhaust system. Why? The answer is simple. Cold air is dense air, and dense air is heavy air. We don't want our engine to be pushing a heavy mass of exhaust gas out of the tailpipe. An extremely large exhaust pipe will cause a slow exhaust flow, which will in turn give the gas plenty of time to cool off en route. Overlarge piping will also allow our exhaust pulses to achieve a higher level of entropy, which will take all of our header tuning and throw it out the window, as pulses will not have the same tendency to line up as they would in a smaller pipe. Coating the entire exhaust system with an insulative material, such as header wrap or a ceramic thermal barrier coating reduces this effect somewhat, but unless you have lots of cash burning a hole in your pocket, is probably not worth the expense on a street driven car.

or maybe this one, don't know what the difference would be when it came to noise, but imo, I think the diesel one would be a little more quiet.

 

be wary of the diesel muffler too. it's designed to dampen certain frequencies (low frequency long amplitude sound) c/t a deisel engine not the higher frequency (buzzy) sound of a high revving 4 cylinder. you may find that the end result is really annoying.

 

there both 11 and 12 lbs shipped, so I'm thinking around the same weight if not a little less by themselves.
