Will this bolt up to MAC LTs and MAC catback on 96-04? Specifically, 98?

Answer This Question I need this answered (0) (0)

Do I need a tune with a new exhaust. Im replacing the stock exhaust on my 2002 Mustang GT with BBK 1-5/8in long tube headers, BBK Catted H-Pipe, and Flowmaster Force 2 exhaust. I already have an Airaid CAI and Flash tuner with 3 custom tunes. When I install this exhaust, do I need a new tune setup?

KDP1362 Year: 2002 Model: GT

  • Yes - any time you install Long Tubes with the Shorty Mid-pipe, you should update your tune files to get the maximum performance gains from the new set up. Hope this helps!

Will these bolt up with v6 long tubes and GT catbacks? I want to use longtubes but i need a catted shorty H pipe for my v6 and can't find one. Will this work or do i need to get one made?

Ziko Year: 2001 Model: V6

  • Unfortunately, this mid-pipe will not bolt up to a V6 properly. This Shorty H-pipe should only be paired with BBK Long Tube Headers for V8 Mustangs.

    great pipe

    This is an awsome h pipe for any aplication. I put this on my 04 v6 with a set of long tubes and everything sealed up great. The sound is deep just like I expected from a good H pipe.

    Very impressed with the fitment and finish. This was used for my long tube project on my 03 V6. These fit with a slight bending outward on the catted end. Will not work without LTs though so dont buy these thinking that. The cats seem to do their jobs as well. Cannot say for sure without an emmisions test though.

    Great mid pipe!

    Ordered this pipe to replace the hollowed converters that were on the car when purchased, and I must say, I'm very pleased. I have the nice nasty deep tone back! The MAC setup I have loves this pipe!

    Quality part, classic sound

    Bought one of these to complement my BBK long tubes and replace the catless BBK X pipe that had been on there before. Bolted up quick and easy and came with enough hardware to install, I bought some more washers and such for a better fit but I love the sound that the H pipe gives me. My only real issue is that everytime I go over a speedbump it hits and knocks the pipe loose causing an exhaust leak but it happened with the old X pipe too so no big deal.

    BBK Catted Shorty H-Pipe

    Pipe was in excellent shape, weld were very clean. Cats are decent size and take away the overly loud yell that off-road pipe have. I'm in Germany and the noise is a huge concern for inspections so they work great! Keep my check engine light off without the MIL blockers. Hightly recommend these for any long tubes that bolt up!

    Works W/ my MAC LTs

    I didn't think this pipe would work with my MAC LT headers so I was surprised when the shop said they did get it to fit. The fit is tight but that's mainly due to the automatic transmission. I would have purchased a MAC short catted H-pipe but they no longer make it. Overall a nice sounding H-pipe, of course an O/R H-pipe would sound even sweeter but I have to pass emissions where I live BOOOOOOOOO!

    Goes along with the BBK Long Tube Headers

    Got this item to go along with a set of BBK long tube headers. My mechanic commented that it was of good quality and matched perfectly with the headers once he had them bolted on the car. The story here is all in the magnificent BBK Long Tube Headers. This catted H-Pipe is just a side show.

    I had the shop install these when i purchased the bbk longtube ceramic headers. the 480$ for install was with the headers included and it was done at a trusted shop that has worked on my car before. This H pipe is very loud. i also have my mufflers cut off. when i drive through parking lots and rev my engine i can set off car alarms every where!!! I <3 these.
