Which catback for Turbo 5.0?

I have a '90 notch 5.0 5-spd with a Quick Time 70mm turbo kit. Bernard fabbed up a y-pipe for me with V-band connections which will get me close with a aftermarket h-pipe. Is there a good 3" catback for a turbo car or will I have to piecemeal one together?

I had trouble finding one for my notch when I got my turbo car going I ended up going with a 2.5" maga flow cat-back. Good luck

Thanks for the advise. What did you use for the mid-pipe?

Thanks again in advance.

Is there a 3" catback available aside from the Flowmaster and MAC chambered muffler kits?

and others, but I haven't tried any of them.


Sorry, it just sank in that you asked about complete catback sytems... not just a bare cat.

i wonder if i should go with a 3'' single ? i think i would miss the dual look.
for now i am going to use my mac 2 1/2'' cat back with a y-pipe then eventually get a non-chambered setup which is better and less restrictive for a turbo setup. But i would like one that is not loud while cruising and idle just under WOT

I am running a 3" single hooker max flow. If I recall two 2.5" are equal to a single 3.5" and two 2.25s are equal to a single 3". If you want to keep duals and just want a catback setup I would get the magnaflow. If you want a single 3" then there is some information out there on them.

The results in HP order:

1.Flowtech Warlock (open) 374.2 hp/ 333.1 tq
2.Bassani Real Street 373.7 hp/ 333.8 tq
3.Hooker Maxflow 373.5 hp/ 333 tq
4.Borla XS 373.3 hp/ 332.6 tq
5.Magnaflow 372.8 / 332.5 tq
6.MAC 372.3 hp / 331.5 tq
7.Flowtech Afterburner 372.3 hp/ 330.1 tq
8.Hooker Aerochamber 372.1 hp/ 330.4 tq
9.Bassani 372 hp/ 333.5 tq
10.Spintech 371.6 hp/ 332.2 tq
11.Edelbrock Performer RPM 370.9 hp / 331.3 tq
12.Borla XR1 370 hp/ 334 tq
13.Flowtech Terminator 369.5 hp / 331.3 tq
14.Dynomax Ultra Flo 369.4 / 333.2 tq

You'd be fine at 2.5" with those parts. If you already have the MAC CB and like it, just weld in some straight through mufflers. BTW, I loved my Borla ProXS on my '04 Cobra.

Not my thread.... but I'm glad to hear you like the ProXS since I have a couple to install once I'm ready. The only bummer is I bought the 3" versions, and while they do have a 3" inlet/outlet, they still neck down internally to 2.5". Kind of a cheap trick.
