    If you ever plan on lowering your car, then no True Duals. They will scrape, and if you do decide on True Duals, then use an X-pipe and not an H-pipe. If you're not planning on lowering your car, then sure go with the TD's. Otherwise, SLP LM.

    Yes. Just ask Mrr23. He has a dyno sheet to prove it.

    Are you gonna have them fabricate an exhaust for you? I'd suggest just buying from Bassani or Texas Speed.

    If you are gonna go true duals go with a Texas speed or Bassani tru duals system because they flow really well with mandral bent tubing-In my opinion the SLP loudmouth sounds like a old dump truck with so much in the car drone your head will explode on the interstate or long trips. I bought a LM and quickly replaced the resonator with a Borla xr1-now it sounds awsome.

    LM is an over rated POS....that is all

    You can get a DynoMax 14" bullet & have your muffler man fab you the rest.

    I did one for $80 + the $30 cost of the Dynomax

    That type of true dual exhaust is illegal in any state that runs a smog program.

    A true dual system done right should be no lower than a Y-pipe system of the same diameter. Its all about running the pipes in parallel to each other in the stock location, and over the axle.
