Pypes H pipe with Borla mufflers

I had many people tell me to go with Bassani. I started lokking at the Pypes on here and reading the feedback. I had a friend with a lift install them on my 2000 Saleen SC and it took about 30-45 minutes. ...

Would it work for a v6 with a gt cat back? Hi I already have a full borla dual cat back on my sixer. But when I bought it I just had an h-pipe goin off the cats then bolting to the cat back. I kinda wanna go catless so I was wondering if this would work on my car running from the stock manifold to the borla catback?

GreyShot

  • No this will not work. The flanges to bolt to your exhaust manifold are not the same as the 4.6 engines.

will this H-pype fit my v6? I would like to know if this pypes would fit my 01 mustang v6, with stock headers, and a stock gt dual exhaust catback that i got and im trying to put on into my v6. I think an X-pype would b too loud , and instead of just buying and an H-pype adapter, I was thinking that I could just buy the whole mid-pype., since I don't wanna cut or weld anything.

    Pypes H pipe with Borla mufflers

    I had many people tell me to go with Bassani. I started lokking at the Pypes on here and reading the feedback. I had a friend with a lift install them on my 2000 Saleen SC and it took about 30-45 minutes. I was anxious to hear how it was going to sound with the Borla mufflers because I've always been a Flowmaster person. The sound it great! Its not to loud but just right. It is a deep muscle car sound and I couldnt be happier. The install was a walk in the park and as stated above, the car sounds great. I would not hesitate to recommend this product to anyone. If you have a Saleen with the Borla mufflers than forget Bassani and go with the Pypes! Don't forget the mil sensors. I hope this helps!

    Imports will fear the thunder!

    I installed this bad boy in about an hour... Then started it up... I think the world may have stopped during that initial start, the. Heavens may have sang, and the ocean roared to match the note that emanated from the 4.6L ford engine. Zeus came down from his throne, just to shake my hand. What a great price for a great buy, thanks AM!

    Pypes Off-Road H Pipe

    So i replaced my stock exhaust with the Pypes O/R H Pipe with Violator Mufflers and i have never heard another mustang with this sound, it tops all my friends stangs with flowmaster 10 and 40 series and there x pipes. The throaty rumble this exhaust puts out has earned itself a perfect 5 star, although it does have a quiet idle once you step on the gas its no longer quiet i recommend this exhaust to everyone who likes the old muscle car rumble, thanks AM for an amazing investment

    Great sound, few snags in the install

    The finished product sounds amazing, nice deep rumble. The difference from the stock pipes to these is night and day. The reason it took me all day to install is because one of the O2 sensor holes on the pipes had not been threaded. It caused a massive headache for me and my friend, had to find a muffle shop that was open and able to fix the problem. Kind of shows badly on quality control for Pypes but still sounds amazing.

    That perfect exhaust note !

    This exhaust is exactly what you want. The x pipe is to raspy and annoying but this h pipe gives you the perfect note. Nice deep rumble with no raspy high end noise. I would recomend this exhasut to anyone looking to free up some extra HP ! I did feel a mid range gain with this mid pipe.
