After doing some research i first wanted the gmpp Exhaust, now that i have seen some vids, pictures, i dont really like the canister, i am looking for a more aggresive canister. I want to go with the Magnaflow muffler, with the Magnaflow cat, with mandrel bent piping, Question is what size piping should i use for best possible gains?

 

Anybody?

 

2.5 seems to be the generally accepted size, 3 inch if you are going to push a lot more power than stock in the future.

 

Thanks for the reply, i have researched some more on the subject, i have a few other questions, Where should i start the piping, just make it a cat-back for best results? Do you know anygood shops in Maryland that can do mandrel bent piping?

 

I got my exhaust done at Altered Atmospeheres. They will make you an exhaust for 599 plus install. They are in Gathersburgs near the airport.

I am sure they would do 2.5 inch as well.

The 3 inch system works great as long as you get the silencer to go along with it.

They don't list it on their website, you have to call them or stop by.

 

Thanks alot!

the cat-back from magnaflow is awesome, but its up to you if you if you want to go bigger!

 

Hey jmc i want to do what you did, so you just ordered one u-bent mandrel piping?

 

Of course you need also the steel clamp and the muffler. Just read the following post before cause it will give you a better idea of the job.
