Hey all,
I've got nearly 13k on my 2013 Si, and I find it's not quite as nice sounding as I want it to be, and the local muffler shop is willing to do a catback for ~150, either magnaflow or flowmaster, but they're saying 3" is too big for an N/A motor.
I've read through a couple of the threads on here (all 11 pages of the magnaflow, and 3 pages for the 2.7 or 3.0) and it seems people either already have supporting mods, or are inconclusive about the sizes.
If I've read all the info right, the stock exhaust is 60mm, or ~2.3", which means a 2.5 would be at least a minor improvement. But, will a 3.0 give any improvement, or is the exhaust shop right and it'll actually rob me of power?
I'm mostly looking for just sound, but I do eventually want (read as: 2 years or so from now) to get a dp, replace the cat converter, a sri, and a tune, but for now I can only get the exhaust (wife's orders, plus I am in the process of restoring a camaro, so most of the funds are going there.)
TL-DR - 2.5 or 3.0? Is 3.0 too big?
Thanks all!
