Mid pipe scraping

[NORTON98]

Right now I have a SLP o/r X midpipe and slp loudmouth 2 catback. I recently lowered my car and my exhaust scrapes lke crazy now. Before it had always bottomed out on speed bumps but now it is really bad.

I figured out that the reason why it scrapes was because the fitment of the midpipe it just hangs to low. So I thought because I still have my stock midpipe I could cut the cats out of it and replace the them with pipes and basically make it a off road H pipe. The reason why this makes sense is because it fits very nicely underneath the car.

But after looking at the stock midpipe it seems that it would be easier to just buy a offroad BBK H pipe rather than modify the stock Midpipe.


Basically my question is which after market off road H pipe would fit well on my 98 GT with out hanging low?

O and I have the stock exhaust manifolds/headers

Thanks,
Mike

I had the same problem... I loosened the midpipe to catvack bolts, then put a floor jack under the mid pipe...I jacked it up till it touched the floorboards, then tightened the bolts back up. ( with the jack still in place) When the jack is lowered the midpipe will sit higher.

I am having the same problem and as soon as the temps get above freezing I am trying this method. The only thing I'm worried about are leaks because it will change the angles at each connection.

I do, but they have the same ball and socket connection.

That's how I fixed mine too.

I did that while it was on the lift with a tranny jack and it works better but that damn chamber sits a lot lower...

I gotta do this too, my SLP X hangs low too.

Thanks for the responses!

Do any of you know how well the BBK o/r H pipe fits on our cars because my slp midpipe actually doesnt fit my car well at all. I cant even do the jack trick that thunder dave mentioned.

About as well, that's the one I had, and I still had to do the jack, and it still wore away at the U bolt in the center.

O ok well then I might modify the stock H pipe to make it an off road H. My buddy at the muffler shop says that he can put high flow cats on my o/r X pipe to make it pass smog does anybody know if those work. He says its guaranteed by the company.

SRT handz I have H&R supersports and I wish it was lower in the front.....What do you have?

My highflow cats have on my Pypes X have passed emissions for 2 years in a row. I have H&R Supersports as well and wasn't satisfied with the height of the front at the time I had ALL isolators in. I took the front ones out and it sits LOW. It actually dropped it 1/2" from just isolators and now has a real slight rake to it instead of the squat like it had before.

In California you can only have aftermarket cats on a OBDI Car (5.0).... Any OBDII car has to have all 6 cats and have to be OEM 100% stock cats to pass. In cali you are not aloud to modify the Mid-Pipe in anyway what so ever or you get sent to the state Ref. (HELL ON EARTH)

Mangaflow doesnt make OBDII cats that pass in california

ding, ding ding. What i always suggest for people having that sagging problem. It helps big time and make sure your hangers are in good shape. IF there sagging than no matter what you do.. it going to scrape like a bitch.
