Just wondering if anyone has ran open downpipe at the track for more power or weight savings? I'm heading out the track this sunday for the last race of the year, and i want to go all out. I have a trailer and tow vehicle ready, so its ***** to the wall racing. I was thinking about removing the midpipe and catback section of my cs exhaust for weight savings and just more flow. Wategate is 40mm and doesnt creep at all with the exhaust. Do you figure i might experience creep? I have enough fuel mods and an rtek1.7 chip for as much boost as the stock turbo can put out, so I shoudl be fine there.

Another conern I had was if I shot flames or something. Thats probably not good to have fire under the car lol. Can anyone attest to this happening? The car is in a good state of tune, as my last set of plugs were a gorgeous golden brown color.

Also the car is gutted to hell now, 1 seat, and just the dash, and I'l be running nitto 555r's. Hoping for under 13.5@over 100mph

thanks

Ryan

 

Thought about it, but with open 3 inch all the way to the RB cat back, it doesnt seem like the reward would be worth the hassle.

 

i wouldnt do it either wont give you much advantage if you have 3'' all the way back it will flow good enough

 

but the 15lbs....lol. Its not really a hassle, I'l just throw it up on a hoist at work and remove it. The car isnt licenced now, so its going to be trailered up to the track and thrashed. Since I can't sell it I might aswell have some fun with it.

 

I think the whole exhaust from the downpipe and back is more than 15lbs, try like 50. I just took mine out its pretty heavy as one whole piece.

 

u know
it would be pretty lame to have a VERY LOUD car run mid 13s...

when a car alot quieter do 12s next to you

u know????

 

blackplague he has a cs exhaust so 15 pounds sounds right. i thought the exhaust system of turbo cars was based on pressure differntial before and after the turbine of the turbocharger? therefore less pressure after is more powerful, but i'd stick with the 3", btw i thought the cs exhaust was 3 1/8"? good luck

 

just make a side pipe that sticks out from underneath the passenger's side. oh, and i hope you don't like your paint job because it'll get cooked in a hurry .

 

iv ran my car a few times with just a 3 inch dp realy ****** loud and it sounds like total **** and i didnt notice any power advantages. if fact it seemed slower but i equate that to loud = fast
weaght saving will be the only +
