Well I've searched all over and it's basically a split decision on the 1 3/4 vs 1 7/8 long tubes debate. Some say the 1 3/4 will be fine up till the higher HP applications BUT if you have the option to buy the 1 7/8 to get them since they dont hurt power and cost about the same.....here's my situation.....

Can pick up a set of Bassani 1 3/4" stainless LTs for about $450 slightly used. Is the cheap price worth jumping on the 1 3/4? I wasn't going to tune just yet but this could change that or if get them I may just wait till next spring to install. What you guys think?!?

 

Thats not a bad price i would get them.

 

i still have the headers for sale. If you don't want them let me know.

here's an old test not your engine but may be helpful

 

I have BBK 1-3/4 long tubes, x-pipe, Steeda CAI and tune. Went from 358hp/351tq stock to 420HP/398tq on a Dyno jet with the hood closed. I was told with a few more miles and better air the numbers would increase a little. Some shops run the Dyno with the hood open which is usually good for another 7-8HP/tq

I have used long tubes on several cars and enjoy the sound more than the power gains. I would bet half of the 62HP gain was from LTs/off road xpipe combo. High flow cats would only take out about 5hp.

One thing people forget about is the improve throttle response and smoothed power band you get from long tubes ( a CAI helps with these as well).

 

been busy lately. Any other opinions?

 

I'm also curious about it, or even what it's truly worth. I am about to purchase my '13 GT, and I'm curious if long tubes are a must have or if the stock exhaust flows well.

 

Danielle, the stock headers flow pretty good. People are in the 9s and 10s with them. But long tubes are good for a decent amount of power and the sound is awesome

 

Wow, that's sort of a relief, because it was pretty much mandatory with a 6 liter GTO.

 

i bought the smaller ones (1 3/4 KOOKS).... i was told from Dez racing that were advised for a N/A motor it would kill the low RPM torque with the larger runners,

i couldn't be happier

 

Mike told you that? Wow. He's dead wrong on that.

 

These headers are still for sale let me know if anyone wants the,
Bassani 1 3/4 headers. I offered the OP a killer deal but i dont think he wants them. So they are up for grabs. 425 plus shipping

 

Kooks told us that

 

Headers sold, thanks Mike.
