Punkin, I went down to my local muffler shop and had the resonator removed and a Y pipe welded in. I think it sounds great! cost $100.00! Some of the guys don't like the sound, but as far as I'm concerned, anything else just shows you have too much money. It's a little louder at idle, comes on strong during acceleration, and the dreaded 'cabin drone' is a very tolerable hum. The best thing is you get to keep the stock tips and the stock muffler. It's all reversible if you just hate it, but I think you'll love it!

 

Pics please. Id like to see what $100 gets.

 

240M3SRT,

You'll have to wait until my car is up on a lift or I get a digital camera that will take a fisheye lense. It looks good. The muffler guy spent some time to get it right. He probably under bid the job, but not by a whole lot.
If you just have to have a perfect tig bead this probably wouldn't be for you but it does look pretty clean and sounds great. You sure are putting a lot of horsepower down on the pavement. I imagine the Corvettes in your area try to avoid you lol.

 

Count me in..........3 inch pipes......prefer stainless w/Magnaflow

In FL now, but originally from your neck of woods........rock island

 

OP, Ive been patiently watching this thread. How have you fared on making this afforable exhaust of which you speak.

A few other questions:

Will it include factory flanges that bolt up directly to the stock center section with no modification? Will it sound good but not be too loud? Are you still planning to obtain before and after dyno results? 100% stainless? Price?

 

New Update Coming Soon.


We Are Working Very Hard On This Project.

The Fuel Pump Is A Big Problem. We Don't Want You All To Have To Relocate The Pump, So The Likely Solution Will Be Single 3" Piping For A 'catback,' And 2.5" Front-pipes(rather Than The 2.25" Stock Ones) Leading Into The 3". We ARE Working On Replacing The Front Cats With Hiflows Into 2.5" Pipes.....
Looks Like JUST The 3" Catback Will Be Very Affordable;
- But The Cost From The Hi-flow Front-pipe Cats All The Way Back Will Be More Than Anticipated. (but Beautiful)

Also, 'totally Bolt-on' Is Not Likely. some Welding Will Likely Be Required (unless You Order Just The Catback)

Feedback Please.

 

I know its not the cost effective way but, would it be really hard to make some sort of heat shield for the pump so you could avoid having to move it?

 

good call on a heat shield. i think we will try to make a 'slimmer' heat-resistant shield if you are willing to pay extra for it.....

thanks for the feedback

 

I posted my 100% stainless catback for $599 shipped with a 23lb weight savings and dyno sheets backing up my 15 whp 20 wtq gains. Only thing it lacked was tips which myself or anyone else could have added for cheap.

Pics on post #49 and #183 of this thread:https://www.crossfireforum.org/forum...t=22326&page=3

Not one person bought it, i ended up parting it out.

It will be a fun project for you no doubt. Have fun building the y-pipe....or burns stainless sells them for around $200. If you use twin canisters youll need two.

 

I personally feel 3" is way too big, considering out displacement or lack thereof. 3" seems like you would start losing backpressure and power.... I know in my 2005 Mustang GT, it was a big no-no to get exhaust too large because of the huge decrease in torque. Long headers were nice though... Just not wide.

I would definately stick with 2.5" in the crossfire but thats just me.

 

Isn't that a little backwards from an engineering perspective? Since the temperature drops as you move away from the manifolds and the gasses condense, You need the big diameter pipes up by the engine, by the time you get to cat back you really don't need them. Might sound a little cooler. I'm sure you already know this but I think you're headed in the wrong direction. Why would I lay out, what's going to turn out to be big bucks if I don't get the bang?

 

good point. but those running 185 pullies, will most likely benefit from ANY larger size exhaust due to the much higher boost.

perhaps 2.5" from front all the way back is a better way to go for those running simpler setups.......

NOTHING with modified cars is ever EXACTLY 'by the book' from car-to-car, sometimes big gains and beautiful torque-DYNOsheets come from the strangest configurations. we will be DYNOing many possibilities.
