Limited Slip Differential Vs Headers
 

Now that my car is paid off at the 113K mark, I'm looking to do some improvements.

Obviously LSD Vs Headers are two very different things.

1. Headers
MBH Motorsports has headers for 1,895 with about 30 Horsepower gain. That's better pricing than I've seen for others. Still pricey. Then there is labor for install Any guess on cost?

2. LSD
Quaife is selling a limited slip for $1,200ish including shipping based on currency conversion . There's no USA distributor but it does come with a lifetime warranty.

Summary
Although the headers pricing isn't bad compared to what's out there, It's still pricey.

Not sure how much Quaife would improve things but it does seem more attractive. i.e. better traction, power, and I imagine steering.
Thoughts?

30 mph gains? you mean HP right?

HP, yes. A little early for me when I wrote this. LOL.

Better to ask in C63 subforum.

LSD is a must to put the power down. No point in having more horsepower if you can't use it.
