Should I buy 4 inch or 5 inch exhaust... And what size is the stock exhaust on a 99 24 valve..

5" will sound deeper but no performance gain

Stock is 3" turbo back. To 4" I believe but I could be wrong. No real performance difference 4" versus 5". But like lukesdiesel said, just sound (and price)

4" with 6" tip is what my dad's 01 has and it sounds great, deeper than my 04 with 4" and 5" tip.

On my first truck I had 5" to a 6" tip and loved the deep tone! Never rode in one with a 4" so I have no real comparison to the sound difference inside the cab.

Mine is 4inch with a 6 inch too sounds great a buddy has 6 inch exhaughst and no tip and it is not much different than mine I don't think

I gota 5" with a 8 inch tip dumped over the axel. Echos off the ground and can hear from from a mile way.

You dont really need 5 inch unless your making over 500 hp. A 4 inch is a good upgrade from the 3 inch. Your EGT's will decrease with a 4 inch and you will likely gain a bit of mileage, and quicker spool-up. But it all a matter of choice. Do you need a 5 inch or just want a 5 inch? How thick is your wallet? A 4 inch is more than plenty.
Ive got an Afe 4 inch turbo-back, to an MBRPmuffler. I later found a 5 inch tail-section on ebay for $60 bucks, shipped. I bought it and had it welded to the back of the muffler and replaced the stainless tip with a 7 inch. It looks awsome and looks like a real 5 inch. No-one's the wiser. :rocking:

I mean money is nothing I ain't worried about price just wanna get some opinions I just wanna be heard from a mile away lol I was thinking 5inch to a 8 inch cat stack is there a kit I could buy that I wouldn't have to buy the whole exhaust then cut if off and waste money? Like a stack kit?

I have a 4" down pipe and 5" to the back. I love the sound of it. Mine and my dads truck both have Diamond Eye exhaust. I think its a great quality system for the best price. My 5" was around $350 without a muffler from thoroughbred diesel. Its an easy install also.

I have a diamond eye 5'' system.. and love it.. as tbird said easy install quality product reasonable price... all my buddies know its me coming before they see me.. so you cant tell me there ain't a difference in sound!!!

Keep in mind tho, whatever you get, get a muffler cuz without one, its gonna be a loud M/F if you do any towing. :c:

That's the idea lol
