i just had 2 flowmaster super 40's welded on. I want to have a X-pipe put on also but retain my catalytic converters. I got 2.25inch flowmasters. What is a good x pipe?

I got my SLP catted x pipe from LMperformance.com. Got a pretty good price.

I have an O/R X-pipe from UPR. The installation went well. The most difficult problem I had was, removing the passenger side 02 sensor near the exhaust manifold. My wrench had a hard time fitting between the starter and exhaust to get a good bite on the sensor to loosen it. As far as having cats, I'm not sure how good UPR's cats are. Haven'r really read anything on them. I also have 40 series flows on my 'Stang. I like the sound of them with the new X-pipe. And for the price... the UPR X is a good buy. I'm happy with mine. And just a side not. I've noticed an increas in fuel milage as well as increased power and RPM... Which are all good things....

I have the Bassani and when it was first installed I had 40 series flows and it sounded horrible. Like I was pulling a line of tincans behind me. I would suggest a good H pipe if you wanna keep the flows. If not, upgrade to Magnaflows. LOL

I had a on road slp catted x-pipe with flos and it sounded terrible. It sounded like tincans. If you are going to go with an X than an SLP on road is a good one but you are definitely going to want different mufflers.
