I see that they make a 304 SS for an 06 model...would that be cat back only?
Is there any other reputable companies that make a 4in SS exhaust for our trucks?
Thanks,
Jim

That is correct.

I believe the cast flange is a 3.5". Add to the confusion but some of the very early built trucks came with the 4" elbow. August/September 2002 time frame.

There are other companies out there, like Magnaflow that makes SS systems, but personally MBRP is one of the better ones.

I think Silverline makes one too, but I've put my faith in the MBRP Stacks!!! They rock!!! Full exhaust with the 4" down included.

silverline, volant and corsa make a 304 exhaust. the corsa will be the most money and will cost you $1000.00 or more, the silverline around $600-650 if you search. call extreme they sell the silverline. there is also dpp they also sell a 304 for your truck.

but the exhaust is the same on a HO or standard output for 03/04 model years

when the 325 came out in 2004.5, they got rid of the HO moniker cause they were all 325's

The dealer print out states I have a 305 HO motor...the valve cover states 305...but after reading some other posts on here and trying to order a MBRP exhaust; I've been told that a 325 is the HO not the 305. So I guess the question is do I have a HO motor or not and what are the differences that make it so different for the firment of an exhaust?

Thanks in advance,
Jim

This is why I was stating he didn't have the SO or the 600, but had a HO. Yes the exhaust is the same on the SO and 03-04 HOs.

I need my bed complete so stacks are not an option...but thanks for the input

I will look into the other exhaust mentioned above...I also contacted MBRP to see if they have any old stock or know of anyone with a T304 full system for my truck...just waiting on a reply
