Im picking up a 05GT with a Bassani axel back with a stock H pipe, Here is the problem I want to go with an OR H pipe because I don’t really like the sound of an X pipe BUT I’ve heard that you should match a straight through design with an X and a chambered with an H. Is this true?
I had a Bassani axle back I loved until I went with a Bassani Xpipe with Hi flow cats.
Sounded like a Honda on Duals.
Tried two other axlebacks (chambered and Straight Glasspack including stock) and still sucked.
I'm sold my Bassani axlebacks already, and will by selling the Xpipe with offroad legs as soon as my headers arrive.
Going to go back to an H-pipe.
To answer the construction question, the Bassani is a Parallel offset perforated tube design with packing. Not quite like a turbo muffler.
The Bassani axle-back is a great system, other than sticking out too far past the bumper IMO. As far as the X or H pipe debate, generally the H will sound lower in tone (not volume, just tone or pitch). However, I've heard several different X pipes on different vehicles and although they are the same basic design, they can sound radically different even on the same vehicle (assuming that you're talking about a catted design, not off-road).
Case in point, atleast with the with Mach 1 platform (I had an '04 Mach previously), a catted Bassani or SLP X pipe with a Borla catback sounded high-pitched and tinny. But, the same Borla catback with a Magnaflow X sounded noticeably lower, and really good in my opinion. That's the other thing to remember: exhaust sounds are totally subjective. What you may dig, I may hate. Gotta take things with a grain of salt.
I have no doubt that I want to go with an H, I just wanted to make sure that they go good together. I had heard you dont go with an H with a straight through muffler nor an X with a chambered.
