I have had shorties on my 6er they worked great for that engine. Now i swapped it over the a 4.6 and I need a new exhaust system because what i have is just a mess of pipes. I was thinking of putting some LTs on there but I need cats. Also I not very well versed in LTs and have read it might cause some valve issues because of lack of backpressure.

I plan on down the road proably a few years of putting a supercharger on it. So would shorties work well with the supercharger.


I just looking for imput on either try and find a complete LT system with Cats or just go with the stock H and cats, throw some shorties on there and put a new aftercat system on there

 

if you can afford it, then the lt's and the catted mid pipe is a no brainer. great complementary mod to a supercharger

 

Longtubes over shorties everyday. Same amount of work to install. If your planning on going FI in the future make sure you buy metal HF cats not the ceramic ones. They will melt with FI. With FI a flow through exhaust works and sounds much better than the chambered ones. I have FI, cams, longtubes, no cats with two sets of flow thru glass packs ie resonators and a flow through rear muffler. Plenty of back pressure.

 

Long tubes. Power gain and no real gain with shorties. Will also help u gain more power in future mods.

Shorties are really only beneficial to these stangs for sound.
Get the most outta your mods when modding and do it right the first go round.

 

Longtubes or save your money. Remember you will need a tune. You won't get valve issues! Ignore all you read on that when it comes to longtubes on these engines. A huge amount of us here, myself included, run catless with longtubes and straight through mufflers. Only way you can flow better is open headers and NONE of us have valve issues or backpressure issues.

 

Longtubes

 

wat

Backpressure is a MYTH. Most of the time when people talk about exhaust system not having enough "backpressure" and losing power, it's actually because they don't have enough exhaust VELOCITY. Usually because they have a crappy muffler or the pipes are too big or something along those lines. You don't want backpressure, backpressure = less flow.

 

Buy mine!

LT's all the way
