I currently have a CAT back CORSA exhuast. My question is if this section (Supersprint BMW E60 M5 Front Connecting Pipes Cat Delete (Section 1).....) will bolt directly on my current system? Also, if I dont replace my stock headers or the Xpipe is there any HP to gain with this MOD? Looking for feedback from anyone that may have tried this already......
We confirm that this Supersprint item (789212) will only bolt to the Supersprint Headers.
If you keep your stock headers & precats, you need a different Supersprint item, the part no.789312, which will be a direct, bolt-on application.
They actually look similar to the pipes shown in the photo, but they have an additional flange in their front section, which connects to the stock headers, directly.
This is a first-step performance modification, which is relatively inexpensive, but it will only provide for a small increase al low rpm, and offer a slightly bigger gain from 5000 rpm on up (+10 Hp at peak).
Nothing to compare to the increase that the full Supersprint headers will get you.
Using your stock, cat-back exhaust, or the Supersprint cat-back system, after the cat-delete pipes, will be irrelevant on the gain.
For the installation with the stock cat-back, you will simply need to purchase a pair of 65mm pipe sleeves, in order to connect the ends of these SS pipes to your cat-back section.
The sleeves are available at your BMW dealer, or from us, upon request. No sleeves are needeed, if you use the SS cat-back.
No welding required. The whole process is a 30 minute job.
