if i can't find a flowmaster catback wit the original 40 series, would the car still sound good if i put on the mac offroad h pipe that's 2.5" and just have the original 40's mufflers welded onto the stock catback that's 2.25"?? would performance be affected cause of the decrease size after the h pipe or would there be no big difference? and if not the flows, what is another great sounding chambered catback??[/align]

Several have done it, you'll probably have a very, very similar sound as if you were to get the full catback. Performance probably won't be any different.

Do it, a full catback is ideal and upgrades your tips, but you won't be hurting with weld ins.

weld in flows are popular here. It's what i have done. Sound is practically identical to a full cat-back. Most of your sound comes from your mid-pipe anyways.

Yeah dude I have a Mac o/r H and Flowmaster 40s welded in. Sounds great. Best sounding Mustang exhuast set up IMO.

Oh and soon to have the Mac LTs laying in my garage installed.

i had that and it was to quiet. I got magnapacks like the flows better just to quiet.

eh, I love my flows and catted x... nice rumble at idle, but once I hit the gas, it gets loud..

so what would you guys recommend for a good h pipe for the flow's original 40's, a mac offroad h pipe or mac offroad prochamber?
