[QUOTE="akurma, post: 15828616, member: 184627"] Got the Pypes pipe-bomb catback delivered earlier this week. The box it was shipped in was absolutely mangled, but surprisingly nothing was damaged or missing! so i tackled that yesterday. I couldn't manage to get the Flowmaster catback off without cutting it unfortunately as the connections where the tail pipes meat the mufflers were so corroded even with a torch and hammer they wouldn't budge. (If anyone wants to make an offer on the flowmaster system PM me) Once that was out of the way i went to work installing the Pypes system, super easy install but was a little odd that the mufflers weren't welded to the pipes going to the midpipe like most systems but it works. Best of all it actually fits unlike the flowmaster unit! I still have to align the exhaust tips but overall pretty impressed with the system for being one of the cheapest stainless steel ones on the market for these cars. I personally like the look and style of the exhaust tips on the flowmaster unit better but I digress.
