Headers installed and new exhaust pics
exhaust looks greet but , why are all the joints welded ? Shouldn't you have clamped some or had a flange on some point so if you have to take some of it off or down .
It's very deep and sounds badass
It's 3" up to the bend. The rear section is the GXP magnaflow kit
I should of had a collector ring welded in. DT recommends welding the collector to the stock cat, so I'm not to worried

Loss of torque down low while cruising around, at WOT after 4500 it pulls very hard. With a full tank of gas and 2 other people in my car I ripped off two 4.95 0-60mph runs last night shifting at 6500. (dashhawk) Car weighs 3860 with me in it so I was pushing 4200 last night.
My trans is on its way out. Shifting like **** and not wanting to go into 4th gear. The torque converter is getting sloppy and it slips going into 2nd while driving round.

Verdad Gallardo I will be having 3.69's with a 3000 stall converter installed real soon. This should bump the RPM up so the engine will be closer to it's sweet spot.
headers kick *** just take some getting used to. My car is not as snappy down low, but is much more responsive above 4000 RPM. Keep in mind that when our trans shifts, the engine never falls below 4000 rpm. Headers with 3" exhaust really pulls hard.
I just can't stand the flex couplers making noise when I accerlerate. The new headers are supposed to have had this issue fixed. I bought an older set new in the box. So this is why I'm having problems. Plus.. I had the exhaust shop add a flex tube before the cat. Sounds like a leak, depending on throttle positions.
Update: 5/29/2011
The throttle response is back better then ever now... Just had to get re-tuned and give the chump..uter a chance to re-learn. The freaking coupler rasp is still there and it's annoying. I'm going to have the exhaust shop lower the crossover pipe and replace the coupler. Gotta make room for the 90mm intake/TB combo.

The headers are much better at WOT. My part throttle loss of power can be blamed on the loss of back pressure at low RPM.

This is good to know, cause I wanted to go to a 3" setup and go to a 3" cutout from my 2.5".
Have you been re-tuned yet? Do you think that has anything to do with the low end loss?
Yes.. I've been tuned. I even tried to go to the track today but there doing a bike only deal.
Scary fast now.... after 80mph Tons of torque steer.
My camshaft was spec'd for headers and was worth every penny!
With a stock engine. I'd just use the Hogan catted downpipe with a Magnaflow exhaust kit. You won't pick up much buy going to 3" all the way back. More like lose a bunch

So your saying 3" from headers back to y then 2.5 out thru muffs,is the way to go?Sorry David just trying to figure out how i want my exhaust re-done.I thought goin 3" from collector into 3" highflow cat thru 3"res into one 3"muff to the back,any thought on this setup???
I was in the group buy but got tired of waiting for DT to give me a call (wich I still have not recieved) So I bought some new in the box headers from another memeber.
With headers, 3" from the collector into dual 2.5" would be the best set up for street/strip use. Gotta run a cat to be street legal. 3" all the way back would be overkill.. Plus ground clearance and fitment would be a real problem. Not to mention expensive.
I'm 3" into 2.5" single, and then dual 2.5"
This is a little restrictive up top so I'm having a cutout installed before the cat on Monday.
The exhaust shop told me that the single 2.5" isn't that bad since I'm using a long section of 3" (Over 50" of pipe LOL)
By time the exhaust reaches the 2.5" single, the gas will have had a chance to slow down.

I asked my exhaust shop about 3" from the headers back (with dt headers) into duel 2.5" and they said that dual 2.5 would be a restriction....
Cause you know 2 2.5 in pipes wont outflow a single 3 inch pipe
And yknow i can outflow a 3 inch pipe right now.
