Hello, Trying to beef up the sound of my 2005 3.7 regcab AT, and heard the Gibsons are pretty good, both sound and performance wise. Does anybody know where to buy them, and what size fits my truck?

thanks, Tommy

P.S. Buying a V8 is not an option

 

i been thinking and looking into the same thing. i got my other parts first but ehxuast is coming in about a month. if u find something that sounds pretty good let me know. right now all i can hear is my intake in the truck. i put a K&N intake system on the truck helped out a lot and changed the factory ehxaust note a little bit. like they alwayz say more air in more air out. intake might have the ehxuast sound a little better

 

I got a flow master 50 series dual in dual out. It sounds awesome. If you have two cats allready I would suggest to get either a dual in and dual out exhaust or get two mufflers. If you get one in and two out you wont get the performance in HP that you want. Im getting cool air intake next.

I doubt all of the claims that you get any noticable performance gain out of a exhaust system.

All of the information you need is on the Gibson site. Dealers and also what fits your rig.

 

Yeeaahhh, I went to their website and only found complete exhaust systems for my truck, did not figure our how to determine what muffler I need... will try again. Thx, Tommy

 

If you go with the standard one in two out exhuast you will not get any more performance out of your truck. If you go with true duals that is two independent system like two mufflers or a muffler with 2 in and 2 out you will get about 10-12 more horse power out of your truck.

 

that dont make much since especialy since they say they both make the same power. the duals might make it higher in the power band being more free flowing but the single outlet should be more low range since its a lil more back pressure but still more then stock
