3" or 2.5" TD's? Numbers in sig, i'm wanting to go with 2.5" TDs for clearance and noise with magnaflow 4x9s. My quesiton is will 2.5" rob very much, if any power over 3" on my setup?

2.5" is enough for 500 hp it seems.......I am gonna change out my stupid 3" Y-Pipe for maybe even 2"......into 3" over axle........I don't go racin' everyone in sight with this car. So sick of hitting every damn bump and crack.[lowered 1-1/2"]

I have had both of them, and had a similar setup on the last motor and found that the 2.5 made more torque and about the same horse and the 3 inch did, don't kill your ground clearance for nothing...

You're probably on the higher end of what 2.5" duals will support, but I too think that it will be enough. By the looks of your sig, you're lowered enough that 3" would be a major clearance issue with 4x9 magnaflows.
I am so sick and tired of my LM and catted Y. I really want to go with some 2.5 true duals out the back. If I supplied my own mufflers, x pipe, tips, and possibly cats, how much do you think it would cost to have something fabbed up out the back with some wingnuts on a flange at the axle?
if youre sub 500 i would do 2.5's. However a competant exhaust fabricator should be able to make a 3 inch system tuck. I fabbed a system that was 3inch on a friends h/c car. He was lowered with a pro kit and never scrapped his exhaust ever.

sorry. I understand now, lol. Yeah, i had 2.5s on a H/C big block pontiac. Just fine. What kind of price do you think i should look for?
