Ok I have read every post on exaust there is and I'm still cofused. what I want to know is there a best 4 inch cat back exaust ? by best I mean flowes the best,lowest egt,most hp and highest tourque ,best fit ,and sounds the best .big polished tips don't mean squat to me.so if anyone has the lowdown let me know.what would be realy nice is a 4 inch no muffler system in stainless mandrel bent at a good price ,I :rant: don't want to pay for a muffler i wont use anyway .and haveing to pay for a muffler delite pipe is not going to get it .are there no manufactures who make a muffler less system in mandrel bent stainless?

I was in the same position you were last week, after searching all the posts, I had a little better idea. I narowed it down to 2 and then focused on those 2. I am getting the MBRP 4" 309 stainless exh. for my 06'. Everybody says that it fits like a glove and the quality is perfect.

Don't know if this will help, but i went with the Silverline catback and I am very happy with results.

MBRP and Silverline are both excellent systems. They are very similar except that Silverline comes with a Dual wall tip for the same price as the MBRP without a tip. We keep them both in stock, if you have any questions, let me know.

IRA51,

Most systems are packaged with a muffler at X cost, so it you remove the muffler the cost is still the same etc so it's kind of hard to eat the difference by removing it from the box.

That said the MBRP has a little different muffler than some with a spiral louver system. Helps flow ever so slightly as compared to the muffler that have straight rows of louvers etc. Wish I could help you more by pulling out a muffler and droping in a muffler delete but it just isn't possible etc. Call us if you have any questions etc.
