i originaly was gonna get just mufflers but now im going to get a full catback even though my pocket is empt ... i got a 98 gt and im looking to get the slp loudmouth 1's. i just want some suggestions on this cat back... i want something LOUD and wondering is there any other exhausts that are louder then this. i checked a couple more mustang forums and seems like everyone agrees that they are the loudest. what do u guys have to say about this setup? and will my car be even louder if i was to get hi-flow cats?

Ya the SLP exhaust sounds really good on the 4.6's.

If you want to hear a clip of one to find out exactly how loud they are go to mustangexhaust.com

If you going to do the high flow cat route you would be better off getting a full H or X pipe with the high flow cats, It will give you better sound and more HP.

I hae a catted SLP X pipe and the SLp loud mouth 1's.It is loud and not sure I have heard any louder except with headers and open pipes. You will lose your mustang tone and start to sound like a chevy or Dodge truck. lol But when you get on it the truck sound goes away.
