theres been a LOT of threads on this topic, try the search. personally, i think 3" duals is overkill unless youre up to around 500hp or higher. just my opinion, good luck!

I personally run a 3 inch dual system but a 2.5 inch would be just fine. 2.5 inch is also way easier to get over the axel if you want to run it out the back.

2.5" all the way (out the back )......have it and love it.....would never do anything larger on a street/daily driver as there just isn't enough room under the car to tuck a 3" up tight (my 2.5" give much more ground clearance and I still hit really high speed bumps). Besides, 2.5" is easily enough pipe for a good 450-500 rwhp.....

3" unless you have some killer speedbumps around your neck of the woods...I only scraped this one particular one if I had someone else in the car with me..
