Is there a big difference between the two in terms of sound? I'm trying to save money by going the weld-in route, will the exhaust tips give me trouble? (not lining up correctly and stuff like that) Anything else I should be aware of?

There is a small sound difference due to the aftermarket system's pipes being larger (2.5") and mandrel bent. They also flow better, giving better hp #'s.

But... it's not that big of a difference if you want to save some money.

BTW- what muffler's are you looking at?

I want to get some MAC Flowpaths and pair it up with the Prochamber. Thanks for the quick reply. Anyone else have some opinions?

i just went ahead with the full catback rather than weld ins because if I wanted the larger exhaust later I would have to buy em anyway. Might as well spend a little more and only have to do it once was my line of thought. But if youre sure youll be happy with the weld-ins I go for it, i just couldnt be sure.

if you can find a V6 that wants dual exhaust you can sell them your stock cat-back and not have to weld in to save money.

I went with weld in 40 series flowmasters. I think they sound good. i too had this debate before i got them. I am glad i went with the weldins. the extra 300 or 400 for 1/4 larger of a pipe and some tips was not really worth it. This is also what the exhaust guy told me. So i took that money and saved it so i can get some headers or a off road x pipe. Just my .02 all the sound clips in the world will not do you any good If you have the money and plan on future mods i woudl go with the cat back.

unless you don't care about performance, don't half-ass it. get the full cat-back. i got my Magnaflow cat-back for less than $320 shipped to my door.

If you plan to get a 2.5" midpipe, why would you want to stay with 2.25" tail pipes?
If you're just looking for a better sound, just weld em in.

The avg price for weld ins is $200, and the entire catback is like 379-399. So it is not 3-400 more.

I just had my Borlas welded in, A strait through muffler welded in will still out flow a chamberd style cat-back.

I still have the stock H-Pipe and have no problems stopping cars with aftermarket H/X and a cat-back.

People expect way to much from H/X pipes and cat-backs. Dual 2.25" is enough for a N/A 4.6.

I went the weld in route and I'm happy with my set up. I didn't like any of the exhaust tips on the cat backs. I installed MRT tips after I welded in the series 50 flows. I like it.

I have welded in Flow Paths and love them. The biggest restriction in our exhausts are the stock mufflers. The Mac Flow Paths are also SS!

My welds ins 40 series were 200 with labor and tax and everything. For a cat back on a cobra (IRS) with labor tax and parts it was 595. that is what i was quoted from a few places. Ford quoted me 150 dollars labor muffler shops quoted me between 75 and 150. I would go with the weld ins. Inless you want to upgrade another part of the exhaust later then cat back.

You gotta do what I did; get the 40 series for $40 a piece off e bay, and have a friend, who can weld, help ya.

Final cost, $106.

Well it would be nice if your friend can help me but you are on the other side of the country.

After reading some of these posts, I think I'm leaning towards the cat-back. I don't want to choke up the Prochamber that I'm getting in the future.

I went the weld in route wiht my Bullets at first...total cost of mufflers plus install was $150.00

Then I decided to go with Spintech Prostreets for a louder more muscular sound. Parts and Labor at the same awesome muffler shop was $170.00

You won't notice the difference in performance between weld-ins and catback...if you're on a budget, go with weldins as it gives you the option of swapping mufflers later on w/out crying over cutting off parts of a brand new catback.
