i saw SLP makes a larger y-pipe that bolts into the stock ypipe location,
http://www.slponline.com/view_produc...RTNUMBER=31030

does that actually make any difrence or just bite the bullet and put on some headers?

i have a set of tes headers rdy to go (still need a y-pipe 100bucks from summit) but i am afraid of breaking the exause manifold bolts when i goto take them out. that would force me to pull the heads but its a daily driver and if i pull the heads no car for a while.

would it be a good alternative to sell the headers on e-bay and use that money for slp's stainless y-pipe?? anyone ever put this on before?

thanks

The stock Y-pipe is very bad on flow. Expect around 15hp with just the y-pipe upgrade.
