I'm glad to hear you figured out what system you want to run, I think that'll sound great!Okay, so i have a 2000 Mustang V6. The previous owner put true dual catbacks on the car and thought a pair of SLP Loudmouth Resonators would sound real good seeing as they do sound pretty sick on a Mustang GT. However they dont on the V6. Now ... he got the piping done properly by american muscle, so i'm not going to have that changed, what i'm looking to do it cut the SLP Resonators and have a pair of oval magnaflows put on instead using the same piping. The pipe on there now is a 2.5". The two things i'm wondering is:
1. is 2.5 inches too big for a V6 with duals anyways?
2. I found a unused pair of new magnaflow oval mufflers from a guy who wants 120$ for the pair. Problem is that theyre 3". Is that going to make a difference on the sound of the mufflers? They would be welded on in front of the rear axle so theres still like 4 feet or so of 2.5 inch before the end of the tailpipes.
1. 2.5" exhaust is absolutely fine on a V6!
2. The only problem you're going to run into is running a 2.5" exhaust and trying to run a 3" muffler. If you're going to weld them in, I'm sure they could use a reducer which should allow you to run that size piping! If the exhaust shop can get it done, I don't see a problem with it.
I hope this helps! Please let me know if you have any questions or need some assistance in the near future.
