I'm only $500 invested in LT's with my install included. 1 3/4 would be perfectly fine on these cars. As far as it "being worth it"...that's all relative. Boss IM's do nothing for these cars. They shift the power and up higher n the RPMs and force you to spin the motor upwards of 7800 RPMs to see max gains out of it. I saw 13 HP and lost 22 ft lbs of Tq. I know I gained HP and Tq with my LT's, so IMO LT's were a great investment. These two mods are the most highly debated mods and people are always going to differ in opinions. All it takes is money...

I picked up more tq and hp when I switched from bbk 1 5/8 to American racing 1 7/8.

Was that because the front sensors were reading off of only one primary tube? My jbas are the same and im wondering if I need to relocate them to the collector.

IMO putting the oxygen sensor in a primary tube is the dumbest idea i have seen. Not only does it restrict flow on that cylinder, it does not give an accurate reading back to the computer.

Im considering throwing extensions on and moving them. I guess I'd need a custom tune though. Im like you, idk why they did that either because it doesnt get a reading from the other cylinders so if they have issues it wouldn't throw a MIL.
