Borla Straight Pipe ?
So I just installed a set of borla straight pipes on my 98 A4 and it obviously sounds a little rough to say the least. I planned on welding in a set of dynomax race bullets into the H pipe to smooth out the idle and easy acceleration tone.
My question is if I saved up for a little longer and bought a borla x-pipe, will this give me a few extra hp and smooth it out a little so it doesn't sound like a farm truck or should I just go ahead and weld in the bullets?
BTW- I'm a big fan of a loud exhaust, thats why I wanted to go this route.

slow98cobra,
You definitely want to save up for the Borla x-pipe.
I initially put the Borla straight pipes (only) on my '98 and hated the raspy sound.
The Borla center section is a bit pricey, however the improvement in sound is just short of fantastic! The Borla center section is a resonator and x-pipe combined in one unit.
It fits well and I had mine installed by Meineke muffler in 20 minutes flat. It definitely does smooth out the sound. The loudness is only slightly decreased and the sound has a much more powerful tone to it. It also just about eliminates, the "burble & pop" on deceleration.

Borla X-pipe is the ONLY way to go the the Borla straight pipes.
No H-pipes, those really are not a good option for the better exhuast systems.
When you put the x-pipe on you will want a professional tune as well.
Good Luck on your project

You are talking about the resonator with dual inlets/outlets correct? Where could I find just the center section?
Also, does anyone have experience with borla's x-pipe without the resonator and straight pipes? Curious about your opinion on the sound.
Thx for the help

no.
Long tube headers, High flow cats ( if your county requires emissions) X-pipe and the straight out the back.
No resonator. How loud? Do you like VERY LOUD ROCK MUSIC. It will be very very LOUD under WOT. and just loud under cruze. Lots of drone.
I dont have bora but do have TPIS LTs, Random Tech High Flow cats, X-pipe and straight pipes, No mufflers. it is VERY LOUD.
DD? Not a chance it would drive me crazy. Resonance? absoulty at every RPM level.
There is a thread on here with pics of Borla or LG headers, X-pipe and straight pipes

I'm not a fan of the pop pop pop sound during acceleration/deceleration. I don't want the exhaust to be quiet just smoothed out if you know what i mean. Right now it just sounds like glasspacks

You will get lots of POP N Gurgle on decel. That is unburnt fuel going though the exhaust then igniting in the exhaust pipes
If you want just smoothed out exhaust then straight pipes may not be for you. They are not smooth. Almost can count which cylinder is firing
a simple Borla exhaust or Corsa exhaust muffler system may be what you are looking for
