OOPS! Screwed up and put this in the wrong part of the forum earlier. I was also typing and talking to a friend at the same time so I left some stuff out, Like perforfance stats:
Stock Exhaust - 143 FWHP
Borla Exhaust - 139 FWHP
SCA Exhaust - 144 FWHP
CarDoc - 148 FWHP
Left this out too, seems to be a really overrated topic here.
Crush Bends versus Mandrel Bends
I would love to have a $1000 mandrel bent custom system but unlike the rest of the planet, I have other bills to pay. I am stuck with what I can afford. You have to understand that 2.5 liter engine is ONLY 155 cubic inches, even with the necking down of a crush bend the flow area is still about 4.2", at the narrowest, this is enough flow area for 355 cubic inches or 5.7 liters. I know that my car sounds better, runs better, and is definitely quicker. Enough about that, on to my original post.
Just thought I would tell you guys about this incredible exhaust system I found last year. I had been searching for about two years for a decent system, from the SCA, Borla and the Bassini they were all way overpriced and the sound was still not right. I was very disappointed until I heard the CarDoc Exhaust System, it was fantastic! I have had the CarDoc Exhaust System installed on my car since September 2001, and to put it lightly, it ROCKS! It is the healthiest sounding exhaust system I have ever had on any car I have owned, and I have owned some killer cars, rat motor Camaros, 440cid Plymouth Fury, small block Corvette, all the way down to a 1.6L Isuzu Stylus XS (a hot little car). All of them had custom exhausts (among other things). This of all of them, sounds the best at idle, midrange, and at full song.
The problem with the factory exhaust along with every other exhaust system that copies the factory layout (Bassini, Borla, SCA) have the same tinny, raspy, ricy ringing sound. It is because of the Y split at the back of the car right before the mufflers. It seems that the exhaust pulses of the engine hammer against the split (the exhaust is forced to make a 90 degree bend) and make the whole exhaust system ring like a bell, or resonate. No matter how trick your mufflers are, or how expensive your mandrel bends are, you cannot get rid of the sound unless you get rid of the Y split. Cardoc's system does this, and does it very well, it really is a trick system. The bends are minimal, and high flowing, the muffler is very heavy duty it is a single in, dual out.
The sound, Ahhh, the sound, imagine a burbly deep idle, a rumbly mid-range, and an almost Ferrari V12 scream at full throttle. There is no raspy, Honda fart-can sounds to be found in this system, this is a take no prisoners, go for broke, hairy-chested, rock-crushing exhaust system. If you are the type of person that likes to remain discrete and undercover this is not the system for you!
There is also some unexpected perks to this exhaust, my SVT is now quieter! Yes it sounds strange but the car is now quieter from the front! It seems that the ringing sound the stock exhaust system (or any of its many copies) makes is gone forever, the back end now has a rich deep burbly idle, a beautiful sound! I have confirmed this about a dozen times now at three different get-togethers with fellow SVT owners. It seems that ringing is a big part of the noise at the front of the car, you can now hear the DOHC sound much clearer at full song. Take a look at it, it is low-cost $350, a great deal!
