Help me decide on MBRP 4 or 5 inch exhaust

[Longhauler]

Im wanting a performance exhaust to help lower EGT's while towing my 5th wheel, but I'm not wanting it crazy loud, or should I say the wife doesn't want it loud. Didnt know what advice you guys could give me between the 4 or 5 inch exhaust by MBRP.

Thanks

I like the 5" just because it filled my cutouts better on my 4th gen bumper. It paired good with my 18" magnaflow and actually made it sound a little louder/deeper!

thinking his CTD in his 03 is a tad different.



Get the big one, and get your wife some earplugs.

For the most part unless you plan to add a decent amount of power (over 500whp) the 4" exhaust will be sufficient and you wont see any benefit going with a 5" over the 4".

go big or go home....my 5" sounds awesome( to me anyway)....sounds like a pete on crack!

Check out sound clips, I'm personally not a big fan of 5" sound but a lot of people are

I'm guessing its not worth about the $150 dollars more for the 5 inch. over the 4 inch. The only other performance mods I have is an Edge tuner and I'm getting a cold air intake and that will probably be as far as I go. I spoke to the customer service guy from XDP and he said my EGT's would be 100 degrees lower with the 5inch over the 4 inch. Thanks for your info everyone

Thanks again for the info guys, I decided to go with the 4 inch and I also got the Airaid Jr Kit for now.

150 more? i got a full 5" with a tip for 250 bucks??

It's mostly a matter of sound preference, like others have said. The drop in EGT from a new exhaust are mostly a result of removing restrictive factory components such as the cat, muffler, resonator, DPF in 6.7 trucks, etc. Pipe diameter between 4 and 5" should be mostly negligible with regard to effect on EGT.

Even the farmboy diesel budget 5" is around $330
Most stainless exhaust are $600 and up

Keep in mind that all 3rd gens are 4" from the factory,except the early trucks which were equipped with the 305/555 motors.They were only 4 inch from the muffler back.

Thanks for letting me know about this website I just got done looking at it. The MBRP 5 inch with a tip through Auto Anything was 497.00 after their 15% off code compared to FBD at $420 and Auto Anythings MBRP 4 inch with tip was $322.00 after 15% off code. I didn't see a 4 inch kit through FBD besides a daul kit. FBD does have a lot better price on the 5 inch, now I'm thinking I might cancel my Auto Anything order and go with FBD.

Did you check out XDP? They usually have good prices and will do a 5% or more discount for forum members/new customers

I did look at XDP and Auto Anything was still cheaper

If you find it cheaper AutoAnything price matches as well.
