Exhaust scraping. What to do?

[OrangCrush]

I installed Texas Speed headers and cj/magnaflow x pipe and it’s scraping with steeda progressives. Which springs do I go with minimum drop or pp springs?

I'd say Steeda minimum drop

BMR SP763. Will raise the front about 0.25" and rear 0.5". Enough to not scrape, still looks great and will ride extremely well.

Anyone tried the steeda spacers?

Anyone tried the steeda spacers?

I've got the 1/4" ones in the rear on my car, no issues at all. I know a few people run the front ones too, but can't remember who.

Nothing wrong with using spacers, but the problem when the springs are progressive is that you might need more spring rate at static ride height as well as more static ground clearance. The alternative would probably involve raising the ride height up more than you might prefer.


I've made my own spring spacers for various cars over the years, from about 1/2" to well over 1".

Depends on how much you are willing to spend. An expensive option is going with air. This way you can have a lower ride height when you want and still clear bumps when you need to. Less expensive option is different springs and struts.

Maybe a skid plate?

I guess my only choice would be to do the minimum drop springs. Would it be a good idea to change out dampeners?

The simple fact of the matter is that, at some point in time, you WILL scrape the pre-muffler merely cuz it's the lowest part of the car. Especially if it's an aftermarket unit. Look at it like 'Car Physics 101'. It will not make any difference what springs you have on your Mustang. Obviously, the higher the ride height, the less chance of the pre-muffler grinding, but it's gonna happen! You just have to take a 'rock crawler' attitude when going over certain speed bumps & in & out of certain driveways. And, even then, you just know yer gonna have to 'suck it up, buttercup' cuz you will still hear that terrible grinding sound.

How much had you lowered the car?

I would recommend running the spring spacers. They are actually on sale currently!

Get some jacking rails, they will scrap before your exhaust does.

They are dual purpose lol

What are you scraping on? I have SP763s and I have whacked my Borla resonator on a couple of particularly poorly installed lego-style speed bumps.
