what would you do?

What size piping would you go with 2'' , 2.25'' , 2.5'' for a lincoln ls 2000 v6 I personally want to go with 2.25 '' but what do you think would be best?

If your looking for gains in the HP department, I would look elsewhere. The exhaust system is one of the worst bangs for the bust, especially with a V6. For what you would spend, you could add a nitrous system to satisfy your need for speed on occasion.

Whats stock size? Then add .25". Thats how I would do it. (Stock 2", so I would go 2.25")

There is another LS post asking the same question .... Having done some 4 and 6 cyl race motors , here are my thoughts ,for what they are worth ... Magnaflow sells a 2.5" ,cat back ,system for your LS . "X" pipe crossover ,2 resonators and 2 mufflers. They have posted dyno results 21 HP gain 20 FT Lbs torque increase..My thought is that 2.25" pipe would not change the results much , if any..most muffler shops can only bend up to 2.25" pipe so the big companies boast 2.5 and 3" systems , so there is no round the corner price comparison and compitition....

We do th v6 in 2.25 and the v8 in 2.50.

Heres the v8 system we have.

Thats the same x-pipe on my M7. Very clean looking under there, by the way! Magnaflow made mine I believe. . .
